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.
