1 x Counter 24 V, 500 kHz, 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 preprocessed. This counter module detects the edges of 24-V signals as pulses, which can be counted or converted in the form of a frequency, rotational speed, or period duration. This 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.
