RB12

Single-channel RS422 Buffer

The RB12 contains a differential RS422 receiver input with selectable termination, and two differential RS422 line driver outputs. Each output is capable of driving one RS422 input with 100 ohm termination or two RS422 inputs with input termination of 200 ohms each.

Use two RB12s to buffer the RS422 signals from a quadrature encoder (one RB12 for A and one for B) to allow a gearing encoder to be used with multiple motion controllers. Simply snap off the side panel of the RB12's DIN rail mount enclosure to access the termination jumper.

Features

  • Connect multiple motion controllers to one encoder for gearing applications
  • RS422 differential transceivers for high noise immunity
  • Selectable termination on RS422 input-high impedance or 220 ohm
  • Compact DIN-rail mount
  • Single +5VDC ±5% power supply
  • Low current draw, 30mA typical (varies with termination impedance of RS422 load(s) on the RB12 outputs)

RPS10

RS-422 Interface & PWM to Start/Stop Converter

The RPS10 converts RS422 signals from magnetostrictive linear displacement transducers (MDTs) into single-ended TTL/CMOS compatible signals.

The RPS/10 can also be configured to convert a pulse-width-modulated (PWM) signal into start and stop pulses for use with motion controllers such as the MC, VMC, MMC and TMC families and other products that accept only single-ended, start-stop signals.

Features

  • Get high MDT position resolution by using multiple recirculations within the transducer
  • RS422 differential transceiver for high noise immunity (220 Ohm input Z)
  • Converts PWM transducer outputs to start/stop signals for motion controllers
  • Compact DIN rail mount package
  • Single +5VDC ±5% power supply
  • Low current draw: 30mA typical

AMP/10

TTL/CMOS to RS422 Converter

The AMP10 converts RS422 differential signals from magnetostrictive linear displacement transducers (MDTs) into single-ended TTL/CMOS compatible signals.

Features

  • Permits magnetostrictive displacement transducers to be placed up to 1000 feet from controller
  • RS422 signals for high noise immunity
  • Requires +15V power supply
  • Small size - 1.5" x 3.0" fits standard 3" rails
