5V 8 Channel Relay Module With OPTO-Isolated Support High and Low Level Trigger 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, 9,12 V, 24V are available ; 4. Each way module can be set 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 ) , 8 relay status indicator ( red ) 7. Interface design humane, all interfaces can be connected directly via terminal wiring leads , very convenient 8. Module size : 141.5mm * 50mm * 18.5mm ( L * W * H ) 9. Has four mounting bolts holes , hole 3.1mm, pitch 136mm * 44.5mm Interface: 1. DC+: Connect to the Positive of the power supply 2. DC-: Connect the Negative of the power supply 3. IN1-IN8: According to each channel, the relay suction can be controlled by high or low level Relay output: 24 wire interfaces, all interfaces are able to be leaded directly with wire. Easy to use. 1. NO1--NO8: Relay module normally open interfaces, relays dangling before the snap, after snap, it's connected to COM. 2. COM1--COM8: Relay common interfaces. 3. NC1--NC8: Relay normally closed interfaces. Relay will be short connected to the COM before snap, it's open after suction. High and low level trigger select port: 1. S1-S8 are 1-8 channels in turns, Choice of
