5V/12V 4 Channel Relay Module/Expansion Board for Arduino(Red Board)

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 Operating voltage 12V;
4. the module can be high or low by a jumper setting trigger;
5. fault-tolerant design, even if the control line is broken, the relay will not operate;
6. the power indicator (green), the relay status indicator (red)
7. the interface design of human nature, all interfaces are available through a direct connection terminal leads, very convenient
8. module size: 73mm*50mm*17mm (L*W*H)

Module interface:
1. DC+: positive power supply (VCC)
2. DC-: negative power supply (GND)
3. IN1,IN2,IN3,IN4: can be high or low level control relay

S1,S2,S3,S4, HIGHT OR LOW LEVER

Relay outputs:
1. NO1,2,3,4: normally open relay interface
2. COM1,2,3,4: Common Interface Relays
3. NC1,2,3,4: normally closed relay interface
