Delay time with CL-AC1 and CL-AC2 basic units

The input delay with AC voltage signals depends on the
frequency. The appropriate values for 60 Hz are given in
brackets.
• On-delay
– 80 ms at 50 Hz,
– 66 ms at 60 Hz
• Off-delay for
– I1 to I6 and I9 to I12: 80 ms (66 ms)
– I7 and I8: 160 ms (150 ms) with CL-AC1
– I7 and I8: 80 ms (66 ms) with CL-AC2

If the debounce delay is switched on, the logic relay checks
at 40 ms (33 ms) intervals whether there is a half-wave
present at an input terminal (1st and 2nd pulses in A). If the
logic relay detects two pulses in succession, the device
switches on the corresponding input internally.
If this is not the case, the input is switched off again as soon
as the logic relay does not detect two successive half-waves
(1st and 2nd pulses in B).
