What is the Wago 750-404/000-003?

This counter is used for frequency measurement. The counter measures the 24 V signal pulse period at the CLOCK input and converts it 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.
