What is the B&R X20cSD1207?

1 safe digital counter input with up to 7 kHz counter frequency

For encoder inputs A-A, A-B, A-A/-B-B/

Sink circuit

Input filter configurable

This module is equipped with 1 safe digital input for determining the velocity. Velocity information can be acquired from AB signals up to a maximum frequency of 7 kHz.

The safe counter module is suitable for safely acquiring velocities for safety-related applications up to PL e or SIL 3.

This module is designed for X20 12-pin terminal blocks.
