Power supply with delayed turn-off relay output for three-condu-
cutor DC initiators (NPN or PNP).
The transformer supplies the initiator with 24 V DC. The initiator
signal activates the relay, at which time the adjustable turn-off
delay becomes effective. This module is particularly suitable for
monitoring cyclic movements, e.g, down-times monitoring of
conveyor drives, ventilators and pumps or stroke monitoring of
valves, die cutters and drilling heads.
A contact element actuates the initiator at regular intervals. If
these pulses cease, i.e. the proximity switch is continuously
actuated (t4-t6) or deactivated (t1-t3), the relay transmits a signal
after the set time has elapsed. During normal operation, the
time function bridges the gaps between regular pulses (t0-t2)
