TB20 Counter Economy 24 V, 1 kHz, 32 bit

TB20 Counter Economy 24 V, 1 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 pre-processed.

The counter module detects the edges of 24 V signals as pulses. The pulses are counted and the count is always available up to date for the PLC.
The count function can be enabled through PLC control commands.
The count can be preallocated or reset through the PLC.
