Features MULTIPLE FUNCTIONS: Time delay relay module add power prevent reverse function, output optocoupler isolation, enhance interference resistant power consumption. Industrial grade circuit board, set parameters after power memory forever, ensure stability. I ROTATABLE MODE: After turning on, press and hold K1 for 2 seconds to enter the selection function mode, which can be selected from P1‑1 to P1‑4 P1‑2 OPERATING MODE: When the relay pulls in Y to disconnect, the signal triggers the start time of X time. The user can set the time when the relay pulls in X and Y, similar to P1‑1. The blue light on indicates the time when the relay is off, and the bl P1‑3 WORKING MODE: Open for X seconds, disconnect for Y seconds, infinite cycle. The user can set the time X and Y of the relay. The time setting is similar to P1‑2. Press K1 to enter the fine tuning settings of this function, start X, turn off Y seconds P1‑4 WORKING MODE: The signal trigger relay draws but does not start timing, the trigger signal disappears and starts timing T. When the time is up, the relay closes; During the delay, the signal is given again, the delay is cancelled, the suction is mai Specification: Item Type: Time Delay Relay Module Working Voltage: DC 12V Static Current: 20mA Working Current: 50mA Signal Source: Positive trigger, PNP, high level effective Output Capacity: Can control DC30V 10A or AC250V 10A or less equipment Service Life: > 100,000 Times Package List:1 x Time Delay Relay Module Package List 1 x Time Delay Relay Module
