Description: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 capabilit consumption.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.Product parameters:1. Size: 64.2mm*34.8mm*18.5mm2. Relay Specifications: AC 220V 10A or DC 30V 10A3. Quiescent Current: 20mA, Operating Current: 50mA4. 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 times, Working temperature: -40~85°CWorking 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 hundreddigital 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 decimalpoint, the decimal point in a bit indicates 0-999minutesin ten represents 0 to 99.9 seconds without a decimal point represents 0-999 seconds; goodchoice, bringing the time setting is completed. Short press K1, enter function offine-tuning settings, trigger the default delay period is invalid, press K1, during the delay trigger active(re-timing), clickon 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: Asignal trigger, digital countdown begins, X seconds after, there lay open Y seconds, then close. Users can set the relay time X, Y; P1-1different time settings similar to the blue lights that set the relay time, blue light indicates setting relay off time. Short press K1, enter function offine-tuning the set, the default trigger is invalid duringthe delay, pressK1, during the delay trigger active(re-timing), then click the first repeat default settings.P1-3 operating modes: Open X seconds, disconnect Yseconds, infinite loop. Users can set the relay time X, Y; time setting similar to P1-2. Short press K1, enter function offine-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; (equivalentto release the button to start timing, commonly used in power-offdelay). Users canset the relay time X; time setting similar to P1-1. Package Included: 1 x 12V/24V LED Automation Delay Timer Control Switch Relay Module PCB Board With White Case
