2-Channel 5V Relay Module
Module Description: 1£¬ the module uses genuine quality relay£¬ normally open interfaces Maximum load: AC 250V/10A£¬ DC 30V/10A; 2£¬ using SMD optocoupler isolation£¬ driving ability£¬ stable performance; trigger current 5mA; 3£¬ the module voltage is 5V; 4£¬ the module can be set to high or low triggered by jumper; 5£¬ fault-tolerant design£¬ even if the control line is broken£¬ the relay will not operate; 6£¬ the power indicator (green)£¬ relay status indicator (red) 7£¬ interface design humane£¬ all interfaces can be connected directly via terminal wiring leads£¬ very convenient 8£¬ module size: 50mm * 41mm * 18.5mm (L * W * H) 9£¬ has four mounting bolts holes£¬ hole 3.1mm£¬ 44.5mm * 35.5mm pitch Module Interface: 1£¬ DC +: positive power supply (voltage required by the relay£¬ there 5V.9V.12V and 24V choice) 2£¬ DC-: negative power connection 3£¬ IN1: 1 channel signal to trigger the end£¬ you can set a high or low level control relay 3£¬ IN2: 2-channel signal to trigger the end£¬ you can set a high or low level control relay Relay outputs: 1£¬ NO1: After a relay normally open interfaces£¬ relay before floating£¬ shorted pull with COM1 2£¬ COM1: 1 relay common interface 3£¬ NC1: 1 relay normally closed port£¬ COM1 relay shorted before and after the pull-vacant 4£¬ NO2: 2-way normally open relay interface£¬ the relay before floating£¬ pull back and COM2 short 5£¬ COM2: 2 Common Interface relay 6£¬ NC2: 2-way normally closed relay interface relay short front and COM2£¬ pull vacant post High and low trigger selection ends: 1. S1 is a relay of high and low trigger selection; 2. S2 high and low for the two-way relay trigger selection; 3. When com and low are short circuit£¬ triggering the corresponding relay is low£¬ while the high end of the short com high trigger
