Three Technologies — One Actuator

Exlar’s Tritex™ Series actuators combine three technologies to deliver for the first time a truly simple and low cost electric alternative for fluid power actuators. Tritex actuators with built-in mechanical converters also replace electric drive systems employing ball screw or gear reducer mechanisms for a complete actuation solution.

Tritex actuators represent an all-electric actuator solution for moving and/or positioning mechanical devices in a large variety of industrial or military grade applications. Tritex actuators eliminate the need for pneumatic and hydraulic cylinders while improving position performance, reducing cycle times and eliminating the maintenance associated with fluid power devices. Ball screw mechanisms, and separately mounted gear reducers are also a thing of the past because rotary to linear converters or mechanical reducers are designed in.

Less is more

The Tritex Series of electric actuators combine a brushless servo motor, servo amplifier and position controller in a single industrial grade enclosure. This eliminates both the external servo amplifier and the expensive and failure prone cables associated with a typical servo system. Component selection, design and installation are completely eliminated. Troubleshooting and debugging of individual components; gear reducers, rotary-to-linear converter mechanisms and the complex wiring layout typical of such a system are gone. The panel space for a separately mounted amplifier and installation of that amplifier are no longer necessary.

Linear Applications

Tritex linear actuators employ Exlar’s patented, inverted roller screw mechanism for converting the rotational motion generated within the Tritex actuator to the highly robust and long-life linear motion required to solve applications that previously required pneumatic or hydraulic cylinders. No additional mechanisms (such as ball screws) are required to convert the actuator’s rotary power to linear motion.

The Tritex linear actuator contains the same control capability of the Tritex rotary actuator. In addition, the Tritex software allows you to create a sequence which causes the actuator, when commanded, to move forward while pressing an object into position. You can establish a pre-programmed force which triggers an event (such as stopping or retracting to another position) or it can maintain that force level until commanded otherwise. The sequence is ideal for assembly, test, and pressing applications.

As with the rotary Tritex, the linear Tritex can be programmed to follow an analog command signal, making it ideal for controlling valves and dampers in process control applications.

Remote Amplifier Option

Normally the Tritex electronics are mounted directly within the actuator’s housing. Exlar also offers the convenience of the Tritex electronics in a remote enclosure, the TRA500 for applications where physical size or temperature constraints don’t allow the electronics to be mounted on the actuator. The remote Tritex electronics work with Exlar’s TSM and RSM Series actuators.

Tritex Linear Series Options

USB port to 2 or 4 wire isolated RS-485/422 converter

Supporting 2-wire RS-485 or a 4-wire RS-422/485 communications, this device is well suited for any application that requires long range or multi-drop capabilities. The TTUSB485 model uses pluggable terminal blocks on the RS-422/485 side and has a pair of LEDs that indicate data being transmitted or received. Model TTUSB485 includes special circuitry that adds 2000 volts isolation protection against ground loops and voltage spikes; and it draws power from the USB port so no power supplies is required.

Simply plug the converter into an available USB port on your computer or USB hub and the device will show up as an additional COM port in the Windows Device Manager. Configured as an additional COM port, the converter is now compatible with your Windows applications.

Universal Serial Bus (USB) has become the connectivity workhorse of today’s PCs, replacing the familiar serial ports. But many commercial and industrial devices still use RS-422/485 interfaces. To connect these devices to modern PCs you need robust and reliable conversion solutions. At the same time, USB ports are becoming more common on commercial and industrial equipment such as point-of-sale peripherals, medical devices, scientific instrumentation, laboratory equipment and other devices. Sometimes these are used in environments where surges, spikes and ground loops are likely to occur.

Features
  • 2000 V RMS optical isolation
  • 15kV EDS surge protection
  • Adds a COM port to your PC
  • Protects against surges, spikes and round loops
  • LEDs for transmit and receive lines
  • USB 1.0, 1.1 and 2.0 compatible (12 Mbps)
  • Automatic configuration on Windows 98, ME, 2000 XP, Vista
  • No power supply required (powered from USB bus)
  • Includes 1 meter USB cable
RS-485 Control

No special software is required to control the RS-485 receiver or transmit line driver. The driver is automatically enabled during each byte transmitted in RS-485 mode. The transmitter is always enabled in RS-422 mode. The receiver is tri-stated during each byte transmitted in the echo-off mode. The receiver is always enabled in the echo-on mode. There are 4.7k Ohm pull-down resistors on the RDA and RDB lines. A termination resistor may be added to R16 if needed.

Dip Switch Set-up

Dip switches allow the module to be configured for two-wire or four-wire, RS-422 or RS-485 modes. In two-wire mode the TDA (-) and RDA (-) are tied together and so are TDB (+) and RDB (+), making multi-dropping this converter into an existing network easy.

Converter Model TT232485

9-Pin RS-232 to RS-422/485 Converter

The Model TT232485 is a feature packed RS232 to RS-422/485 9-pin converter. It converts unbalanced, full or half duplex RS-232 signals to balanced, full or half-duplex RS422 or RS-485 signals at baud rates up to 115.2 kbps. In addition, the unit optically isolates and surge suppresses the RS-422/485 lines. The driver uses automatic SD (send data) or TS (handshake) control, or can be configured as always enabled for use in RS-422 systems.

A dipswitch selects communication features on the TT232485. Two LEDs show data traffic in either direction. Only one power supply is necessary, located on the RS-232 side. The isolated power and ground on the RS-422/485 side are generated internally.

Connections are made through a DB9 female connector on the RS-232 side and terminal blocks on the RS-422/485 side. All terminal blocks, dipswitches, and jumpers are located inside the hood and are reachable through the access panel, which slides closed to protect the connections.

The RS-232 port has a DB9 female connector with pins 3 (TD), 2 (RD), and 5 (Signal Ground) supported, pins 7 (RTS) and 8 (CTS) are tied together, and pins 6 (DSR), 1 (CD), and 4 (DTR), are also tied together. The 485OT9L has two LEDs: a Transmit Data LED showing when data goes from the RS-232 side to the RS-485 side, and a Receive Data LED showing data going from the RS-485 side to the RS-232 side. These are very useful for determining if data is getting through the converter. The RS-485 terminal blocks support Transmit Data (A) and (B), Receive Data (A) and (B), and Signal Ground. A single supply voltage of 10 to 30 VDC on the RS-232 side powers the unit. An 8-position dipswitch allows the selection of baud rate, 2-wire or 4-wire mode, echo on or off, and termination in or out.

RS-422/485 Driver Control

The TT232485 uses either RTS Control or Send Data Control to enable the RS-485 driver. This option is user selectable by setting push-on jumpers located next to the terminal blocks. RTS controls the driver using toggling Request to Send (pin 7) of the RS-232 side. Raising RTS enables the driver and lowering RTS disables it. Automatic Send Data Control recognizes the first bit of data from the RS-232 side, enables the transmitter and disables the receiver. After the last bit of data is sent from the RS-232 side, the TT232485 waits one character length then disables the transmitter and enables the receiver. The timeout can be selected with dipswitches or by changing the value of R21 (see Table, Baud Rate Selection). The timeout is preset at the factory for 9600 baud. Removing both sets of jumpers completely will constantly enable the RS-485 driver. This makes the TT232485 behave like an RS-422 converter. For settings, see Table, Standard Communications Settings.

Termination and Echo Options

Termination resistance can be selected with Switch 8 for high baud rates and long cable distances. The 4-wire/2-wire switches (6 and 7) are turned off for 4-wire mode and on for 2-wire mode. When they are set on, they connect TD(A) to RD(A) and TD(B) to RD(B) internally. Switch 5 controls Echo on and off. When switch 5 is in the off position the receiver is constantly enabled. Placing the switch in the on position allows the driver or the receiver to be enabled at any time. In 2-wire mode it is recommended that switch 5 be turned on to prevent data being set out from “echoing” back through the receiver. Up to 32 receivers can be driven by any one RS-485 driver, allowing you to put together large systems with many drop points.

TTSR1 Shunt Regulator Option

Transient over voltage problems are quickly solved using shunt regulators that clamp regeneration voltage to safe levels. These simple devices can increase system reliability by stabilizing voltage fluctuations and eliminate over-voltage shutdowns.

The purpose of a shunt regulator is to ‘burn off’ excess regeneration energy that is produced when a drive brings a large load to a stop. Mechanical braking systems use friction to stop a load and convert kinetic energy into heat. Servo drives on the other hand are very efficient power converters – typically over 98%! They convert electrical energy from the motor to the power supply just as efficiently as when they convert energy from the power supply to the motor. During a rapid deceleration or the deceleration of a large load, enough excess energy can be transferred to shut down the drive or damage the power supply.

A shunt regulator ‘clamps’ the power supply voltage to a set level and prevents unexpected shutdown or damage. It monitors the power supply voltage and if the voltage exceeds the set limit, the shunt regulator ‘bleeds off’ the extra voltage through a power resistor. The shunt regulator is only active when the voltage exceeds the set level; otherwise, no current passes through the power resistor. The shunt regulator automatically turns the power resistor on and off as necessary to regulate the voltage, sometimes up to several hundred Hertz.

 

Description

The TTSR1 shunt regulator is designed to work with four quadrant regenerative servo amplifiers. During braking most of the stored mechanical energy is fed back into the power supply, which charges the output capacitor to a higher voltage. If the charge reaches the amplifier’s over-voltage shutdown point, motor control and braking will cease. To ensure smooth braking of large inertial loads with use of a shunt regulator is recommended. Verify the need for a shunt regulator by operating the servo under the worst case braking condition. If the amplifier shuts off due to over-voltage (blinking red LED) a shunt regulator is necessary (typically during downward move or deceleration).

 

Operation

When the DC bus reaches the shunt voltage of the shunt-regulator assembly, the voltage comparator unit turns on the electronic switch, which connects the R1 power resistor across the DC bus. This power resistor dissipates the energy from the DC bus. After the bus voltage is reduced to less than the shunt voltage setting the resistor is disconnected from the bus. A small hysteresis loop allows time between switching. The TTSR1 assembly is available with standard shunt voltages of 50, 70, 80, 90, 135, 175, 185, 380 and 400 Volts.
