Feature:1. Trigger start count down, the relay is immediately turned on, and the relay is turned off after the countdown ends. The middle trigger stops immediately.2. 2-digit red digital tube, the remaining time is displayed during the count down, otherwise the set time is displayed.3. Time adjustment by 500K potentiometer, dynamically displayed on the digital tube during adjustment.4. Passive output mode, dry contact, dead, switching value, equivalent to switch.5. Accuracy is 1 second or 1 minute, depending on the jumper setting.Specification:Item Type: Delay Relay ModuleVoltage: 220V AC (160V-250V can work)Power Consumption: 1.0WTime Range: 1-99 seconds or 1-99 minutesDisplay Mode: 2-digit red digital tube (the remaining time is displayed during the countdown, otherwise the set time is displayed)Time Adjustment: Potentiometer (500K), dynamically displayed on the digital tube during adjustmentAccuracy: 1 (seconds or minutes, set according to jumpers)Error: 2%Trigger Mode: Shorted for more than 0.02 secondsOutput Contact: A set of normally open + normally closedOutput Capacity: 10A (voltage range 0-250V AC, or 0-30V DC)Output Mode: Passive (dry contact, dead, switching value, equivalent to switch)Interface Description: L 220V input live wireN 220V input null lineNO Normally open terminal of relayCOM Common terminal of relayNC Normally closed terminal of relayNote: ON in the function description means that the relay is connected between common and normally open.Package List:1 x Delay Relay Module
