2PCS DC 12V 8 Channel Relay Module with Optocoupler Isolated Support High and Low Level Trigger 8 Ways Relay Switch Module (12V)

Features:1. The module normally open interfaces Maximum load : AC 250V/10A, DC 30V/10A.2. Using SMD optocoupler isolation , driving ability , stable performance ; trigger current 5mA.3. Each way module can be set high or low triggered by jumper.4. Fault-tolerant design , even if the control line is broken , the relay will not operate.5. The power indicator ( green ) , 8 relay status indicator ( red )6. Equipped with fixing screw hole, easy to install. Has four mounting bolts holes , hole 3.1mm, pitch 136mm * 44.5mm.7. Input terminals can be arbitrarily set high and low level, the control mode is more flexible.8. The input and output are 5.08mm wiring terminals, wiring is more convenient, suitable for PLC control.Module Interface :1. DC +: 12V positive power supply2. DC-: negative power connection3. IN1-IN8: each way based on the settings , can be high or low to control the corresponding relayRelay outputs : 24 line interface, the interface can be directly connected to all leads , user-friendly1. NO1 - NO8: normally open relay interfaces , relay before the vacant after the pull shorted with COM2. COM1 - COM8: Relay Common Interface3. NC1 - NC8: normally closed relay interface relay shorted with COM ago , after the pull- vacantHigh and low trigger selection :1.S1-S8 in order to relay a road -8 way high and low trigger selection ;2.Com with low short circuit , triggering the corresponding relay is low , while the high end of the short com high triggerPackage Included:2*12V 8 Channel Relay Module With Optocoupler
