6.4 OFF-delay
3RP2535 time relay - OFF-delay with control signal
The time relay contains 1 CO contact.
A continuous supply voltage (A1/A2) is present on the time relay. If a control signal is applied
to B1, the output relay switches over. The set operating time starts when the control signal is
switched off. A minimum ON duration of ≥ 35 ms must be observed. If the control signal is
applied again after the time has started, the time is reset. If the control signal is withdrawn,
the time starts again (retriggerable).
7 time ranges can be set with the time range selector switch:
● 0.05 s - 1 s
● 0.5 s - 10 s
● 5 s - 100 s
● 0.5 min - 10 min
● 0.05 h - 1 h
● 0.5 h - 10 h
● 5 h - 100 h
Note
The desired operating time is set precisely with the operating time adjustment switch.
