4 Channel 5V Red Board Optocoupler Isolation Relay Module

It is a 4 Channel Isolated 5V 10A Relay Module Opto-coupler, A wide range of microcontrollers such as Arduino, AVR, PIC, ARM and so on can control it. It is also able to control various appliances and other types of equipment with a large current.

Module interface:
1. DC +: the positive supply (voltage relay according to the requirements)
2. DC-: negative one
3. IN: can be high or low level relay control
Relay output:
1. NO: normally open relay interfaces, floating suction before closing the relay, after the short circuit is absorbed and COM
2. COM: Common Interface Relays
3. NC: normally closed relay interfaces, COM and close the front relay short circuit, the pull vacant
High and low end trigger selection:
1. LOW when the shorting jumper is level-triggered;
2. to trigger high and high jumper shorted.
