Parameters: Operating Voltage: 6--30V(Support Micro USB 5V Power Supply)Trigger Source: High Trigger (3V-24V)Output Capability: DC 30V or AC 220vQuiescent Current: 20mAOperating Current: 50mAWith Optocoupler Isolation, Enhanced Anti-Jamming Capability NOTE: The Relay Outputs are Passive Contact, Uncharged Output to Control a Line-Off Role Timer Relay Module Features: One-Key Emergency Stop Function (STOP Key), With Reverse Connection Protection, Reverse Connection Will Not BurnTimer Relay Module Added Sleep Mode. After Enabling, If There is No Operation within 5 Minutes, the Display Will Be Turned Off Automatically; Module Can Be Wake Up By Any KeyDifferent OP, CP, LOP Parameters Can Be Set, These Parameters Are Independent of Each Other and Saved SeparatelyAll Setup Parameters are Saved Automatically Power Down Sleep Mode: C-P Sleep Mode: 5 Minutes Without Any Operation, the Digital Display Automatically Turns Off, the Normal Operation of the Program O-D Normal Mode: Digital Display Always Open Press STOP Button for 2 Seconds after the Release, to Switch C-P and O-D State, in Which the Current State of Flashes and Then Return to the Main Screen Operation Modes: P1: Upon Signal is Triggered, the Relay Conducts OP Time,Then Turn Off. Operate Within the OP Period As Followsa: P1.1: Signal Being Re-Triggered is Ignoredb: P1.2: Signal Being Re-Triggered to Reclockc: P1.3: Signal Being Re-Triggered to Reset, the Relay Contact Disconnected, Stop TimingP2: Feed Trigger Signal, the Relay Closed CL Time, Then Conducts OP Time. After Timing, Turn Off the RelayP3.1: Feed Trigger Signal, the Relay Conducted OP Time, the Relay Closed CL time, then repeat above actions, re-trigger signal within the timing cycle, the relay contact disconnected, stop timing. The circuit times(LOP) can be set.P3.2: No need to trigger signal when power on, the relay conducts OP time, the relay closed CL time, then repeat above actions.The circuit times(LOP) can be set.P4: The function of remaining signal: the timing will be reset upon signal is triggered, relay contacts stay connected. when no signal, turn off the relay after timing OP.
