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 Module Voltage: 220V AC (160V-250V can work) Power Consumption: 1.0W Time Range: 1-99 seconds or 1-99 minutes Display 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 adjustment Accuracy: 1 (seconds or minutes, set according to jumpers) Error: 2% Trigger Mode: Shorted for more than 0.02 seconds Output Contact: A set of normally open + normally closed Output 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 wire N 220V input null line NO Normally open terminal of relay COM Common terminal of relay NC Normally closed terminal of relay Note: “ON” in the function description means that the relay is connected between “common” and “normally open”.
