Description12V 2 Channel Red Color Relay Module1. Maximum load:AC 250V/10A, DC30V/10A 2. SMD optocoupler isolation, strong driving ability, stable performance; trigger current 5mA 3. the module voltage 12V 4. each channel 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. power indicator (green), 2 relay state indicator (red) 7. interface design user-friendly, all interfaces are available through the wiring terminal direct connection leads, very convenientModule Port :1. DC : DC power supply positive 2. DC-: DC power supply negative 3. IN1: Channel 1 signal trigger terminal 4. IN2: Channel 2 signal trigger terminalRelay Output :1. NC1: Channel 1 relay normally closed pin. 2. COM1: Channel 1 relay common pin. 3. NO1: Channel 1 relay normally opened pin. 4. NC2: Channel 2 relay normally closed pin. 5. COM2: Channel 2 relay common pin. 6. NO2: Channel 2 relay normally opened pin.High And Low Level Trigger Option :1. S1: It is option switch for channel 1 relay. 2. S2: It is option switch for channel 2 relay.
