1 CH Signal Trigger Time Delay Relay Board Digital LED Display PLC Cycle Timer Control Switch Timing Relay Module DC 12VDescription:1. New upgrades to simplify,to meet customer needs.2. Increase the supply anti-reversefunction.3. The use of opto isolated input and output,enhanced anti-jamming capabilitconsumption.4. Set parameter after power for ever memories.5. Signal terminal voltage signal can be maintained for a longtime.6. To ensure stability, industrial grade board, class PLC. Parameter:1. Size: 64.2mm*34.8mm*18.5mm.2. Relay Specifications: AC 220V 10A or DC 30V 10A.3. Quiescent Current: 20mA, Operating Current: 50mA.4. Working voltage: 10~16V (if other ranges can be customized).5. Signal voltage: 4V~20V (if other ranges can be customized).6. Life: about 100,000 times7. Working temperature: -40~85 Celsius. Working mode selection:After power on,long press K12 seconds later into the select function mode,P1-1~P1-4forchoose.P1-1 operating modes:a signal to trigger relay, time is up,the relay disconnect users,You can set relay time T,click K2 the hundred digital tube starts flashing,then press K3, the hundred digital change; click K2 ten digital tube starts flashing,then press K3,ten digit changes;click K2 bit digital tube starts flashing, then press K3, single-digit change;then click K2,; digital pipe does not blink,then press the K3, shifting the decimal point,the decimal point in a bit indicates 0-999 minutes in ten represents 0 to 99.9 seconds without a decimal point represents 0-999 seconds;good choice,bringing the time setting is completed.Short press K1, enter function offline-tuning settings,trigger the default delay period is invalid, press K1, during the delay trigger active(re-timing), click on the K1, during the delay reset (timer turned off,the relay reset) press again to repeat the default settings for the first time.P1-2 operating modes: A signal trigger ,digital countdown begins,X seconds after,there lay open Y seconds,then close.Users can set the relay time X,Y;P1-1 different time settings similar to the blue lights that set the relay time,blue light indicates setting relay off time. Short press K1, enter function offline-tuning the set,the default trigger is invalid during the delay,press K1,during the delay trigger active(re-timing),then click the first repeat default settings.P1-3 operating modes:Open X seconds,disconnect Y seconds, infinite loop.Users can set the relay time X,Y;time setting similar to P1-2.Short press K1,enter function offline-tuning set,The default function is:set up an electric circuit the relay first open, press the K1,there lay first close.Press again to repeat the default functionality.P1-4 operating modes:a signal to trigger the relay open but do not start the timer,when the trigger signal disappears,digital count down begins,X time after,the relay close; During the delay,again to the signal,digital count down canceled, stays energized, the signal disappears, restart count down; (equivalent to release the button to start timing, commonly used in power-off delay).Users can set the relay time X; time setting similar to P1-1. Package Included:1 * Digital LED Display Time Delay Relay Module
