Descirption: brand new and high quality Features: New upgrades to simplify,to meet customer needs. Increase the supply anti-reversefunction. The use of opto isolated input and output,enhanced anti-jamming capabilit consumption. Set parameter after power for ever memories. Signal terminal voltage signal can be maintained for a longtime. to ensure stability,industrial grade board,class PLC. Product parameters: Size:64.2mm*34.8mm*18.5mm. Relay Specifications:AC 220V 10A or for DC 30V 10A. Quiescent Current:20mA,Operating Current:50mA. Working voltage:10~16V (if other ranges can be customized). Signal voltage:4V~20V (if other ranges can be customized). life:about100,000times,Working temperature:-40~85'C. Quantity: 1Pc 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, for time is up,the relay disconnect users,You can set relay for time for 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 decimalpointin abitindicates 0-999minutesin ten represents 0 to 99.9 seconds withou tadecimalpointrepresents 0-999 seconds;goodchoice,bringing the for time setting is completed.Short press K1,enterfunction offine-tuning settings,triggerthedefaultdelayperiod 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 for 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 for time X,Y;P1-1different for time settings similar to the blue lights that set the relay for time,blue light indicates setting relay off for time. Short press K1, enter function offine-tuning the set,the default trigger is invalid during the 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 for timeX,Y;for 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 for time after,the relayclose; 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 usedin power-offdelay).Users canset the relay for time X; for time setting similar to P1-1. Package includes: 1 x DC12V Delay Timer Control Switch Module
