Wago 750-638 WAGO I/O-SYSTEM 750 Function and technology modules
2-Channel Up/Down Counter, Counter depth: 16 Bit, Input filter: 0,2 ms, Signal characteristic: Differential, Switching frequency max.: 500 Hz, minimum pulse width (0/1): 1 ms
The I/O module has two counters that count 24V DC binary pulses independently of one another.
The data is then transmitted to the control via the fieldbus.
The counters can be set or reset with the control bytes. A counter lock-out is also possible.
The control bytes also determine the direction of counting.
