TDD2 Manual

February 23, 2017

Product Specification and User Manual for Transducer Display Model TDD2

The TDD2 displays position information derived from a magnetostrictive transducer with Synchronous Serial 
Interface (SSI), Start/Stop, Pulse Width Modulated (PWM), or CANbus output. Setup of units, offsets, and other 
items can be accomplished via the front-panel keypad menu or a RS-232/485 interface.
 

Features

Multiple magnets supported when using Start/Stop or CANbus sensors

Resolution to 5 micron for Start/Stop transducers

Capable of auto-detecting PWM, free-running PWM, and Start/Stop sensors

Capable of supporting MTS G-Series sensors

Programmable decimal point, units, scale, and resolution

Optional 5-channel programmable limit switch, solid-state or mechanical

Optional 16-bit analog output with programmable range

Two digital inputs allow actions such as remote zero and front panel disable

RS-232 and RS-485 serial interface for host setup and position inquiries

Removable 3.5mm Weidmuller type screw terminals for connections

Setup values stored in non-volatile EEPROM memory

Specifications

Six 0.57 inch red LED digits 

Capable of displaying -199999 to 999999 with a decimal point to the right of any character

Integral units: inches, feet, millimeters, centimeters, or meters

SSI Interface: Clock frequency 227 kHz; External Clock 500 kHz maximum

Update rate: 200 Hz; External update rate 4 kHz maximum

9600 or 19200-baud RS-232 and RS-485 serial interface

Optional five-channel programmable limit switch with programmable on/off points for each channel

Solid State limit switch channels each capable of sinking 500 ma at 50V

Analog retransmission output based on position, velocity, or a forced level

Output ranges: 0-5V, 0-10V, -5-5V, -10-10V, -2.5-2.5V, -2.5-7V

Chip-select output for 3 wire SSI sensors such as rotary encoders

Input Power: 9 to 26.4 VDC (transducer power supply) Except RA option which requires 20 to 26.4 VDC

Housed in 1/8 DIN metal enclosure: 3.78in wide, 1.89in high, 4.68in deep, panel cutout: 3.6in x 1.75in
