3V 5V 12V 24V 8 Channel Relay Module High and Low Level Trigger with Optocoupler Output Way for(12v)

relayModule description:1. The module adopts genuine high quality relay, the maximum load of normally open interface: AC 250V/10A, DC 30V/10A;2. Using patch optocoupler isolation, strong driving ability, stable performance; trigger current 5mA;3. Module working voltage is 3V/5V12V24V4. Product size: 142*50*17 mm5. The module can be triggered by a jumper to set a high level or a low level;6. Fault-tolerant design, even if the control line is broken, the relay will not move;7. Power indicator (green), relay status indicator (red)8. The interface design is user-friendly, all interfaces can be directly connected through the terminal block, which is very convenient.9. With 4 fixing bolt holes, hole 3.1mmModule interface:DC+: Connect to the positive pole of the power supply (voltage is required by relay)DC-: connected to the negative pole of the power supplyIN: can control the relay to pull in high or low levelRelay output:NO: The relay normally open interface, the relay is suspended before the suction, and the short is connected with COM after the suction.COM: Relay common interfaceNC: The relay normally closes the interface, and the relay is shorted to COM before the suction is closed.
