Description
24 VDC encoder inputsSSI, ABR, AB or event counters for inputsPulse width modulation for outputs24 VDC and GND for encoder supply
This module is a multifunctional counter module. It can be connected to one SSI encoder, one ABR encoder, two AB encoders or four event counters. Two outputs are available for pulse width modulation. The functions can also be mixed.
