Wago 750-404/000-003 WAGO I/O-SYSTEM 750 Function and technology modules
1-Channel Frequency Counter, Counter depth: 32 Bit, No. of digital Outputs: 2, No. of Counters: 1, Signal: DC 24 V, Input current typ.: 5 mA, Output current per channel: 0.5 A, Output current: short-circuit-protected, Switching frequency max.: 100 kHz
The counter is used for frequency measurement here, with the pulse period of the 24V signal being measured at the CLOCK input and then converted to a frequency value.
Measurement is enabled and inhibited via the GATE input.
Digital outputs DO 1 and DO 2 can be set using the control byte.
