Function module – 1 x counter 5 V (RS422), 4 MHz, 32 Bit

Counters are used to detect pulses that are faster than a controller’s cycles, i.e., signals that the controller will be unable to detect properly and that therefore need to be pre-processed.

The counter module detects the edges of 24 V signals as pulses. The impulses can be counted or converted into a frequency, rotational speed, or period. The counter module features an additional 24 V input and a 24 V output for a direct response to start pulses and to quick system state changes.
