PW 1D-1D

Level Converter

PW 1D-1D

  • Directional decoder functionality
  • Potential separation
  • High frequency range
TTL / RS422

Level converter for separation and conversion of digital signals.

The PW 1D-1D universal level converter, directional decoder, and potential isolation amplifier accepts both single-track and dual-track incremental encoder signals on its input, which can be designed either as RS422 / TTL or as HTL level (10 to 30 V). If the signal is related to the direction of rotation, the direction can be specified either by a 90° phase shift of channels A and B or by a static direction signal
The module is quickly and easily mounted in the control cabinet on a standard DIN rail.

  • High frequency range up to 500 kHz.
  • Potential isolation amplifier.
  • Level converter and direction decoder for incremental
    encoder signals.
  • Signal inputs (A, /A, B, /B, 0, /0) can be set to HTL, TTL or
    RS422 levels.
  • Processes signals with direction, synchronous, asynchronous,
    as well as single-track signals.
  • Signal outputs (A, /A, B, /B, 0, /0), can be set to HTL, TTL or
    RS422 levels.
  • Conversion of an A/B direction information (90°) into a static
    direction signal and vice-versa.
  • Encoder connection either with Sub-D connector or plug-in
    screw terminals.

  • Potential separation between sensor and control.
  • Level adaptation for old controls with direction signal input.
  • Conversion from TTL into HTL and vice versa.
  • Voltage level adaptation to the application.
