Wiring Port Overview
- AC: Alternating current input power supply
- IN: Signal input terminal (negative-pole triggered)
- NO: Normally open interface — suspended before engagement, short-circuited to COM after engagement
- COM: Common relay interface
- NC: Normally closed interface — short-circuited with COM before engagement, open after engagement
Operating Modes (P-11 through P-35)
This module offers 18 programmable operating modes to suit virtually any automation scenario:
- P-11: Point operation — relay engages with signal, stops when signal disappears
- P-12: Self-locking — one signal to engage, another to stop
- P-13: Timed engage — relay auto-stops after set duration; re-trigger during delay is ignored
- P-14: Timed engage with re-trigger — re-trigger during delay resets the timer
- P-15: Timed engage with stacked timing — re-trigger adds time to the running delay
- P-16: Timed engage with reset — re-trigger during delay resets output
- P-17: Signal-on timing — relay engages on signal; times out after set duration; re-signal during delay maintains output
- P-18: Power-on immediate engage — relay engages on power-up, de-energizes after set delay
- P-21: Signal-off delay engage — relay engages after set delay once signal disconnects
- P-22: Delayed engage — relay engages after set delay; stops when signal disappears
- P-23: Signal-absence engage — relay engages after signal absent for set duration; stops on signal return
- P-24: Dual-threshold — relay engages when signal present longer than set time; stops when absent longer than set time
- P-25: Extended signal engage/stop — both engage and stop triggered by signal exceeding set duration
- P-26: Alternating timed output — relay runs for set time on signal, then on signal disappearance
- P-27: Pulse-detect mode — relay engages while pulse detected; stops after set delay when pulse absent
- P-28: Power-on delayed engage — relay engages after set delay on power-up; runs until power-off
- P-31: Infinite cycle — relay runs ON for A seconds, OFF for B seconds, repeating; stops on power-off
- P-32: Signal-controlled P-31 cycle — loop starts on signal, stops when signal disappears
- P-33: Toggle-controlled P-31 cycle — one signal starts the loop, another stops it
- P-34: Delayed cycle — relay engages after A-second delay, then stops after B seconds
- P-35: Signal-triggered delay cycle — signal starts an A-second delay, then relay runs for B seconds
