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 high and low level trigger 2. When the COM is shorted connected to the Low, the relay was triggered by low level. When the COM is shorted connected to the High, the relay was triggered by high level.
