【E-WOITD】 3.3V 5V 12V 24V 1 Channel Relay Module High and low Level Trigger Relay Board

E WOITD. Module description: 1. The module adopts genuine quality relay, the maximum load of the normally open interface: AC 250V10A, DC 30V10A, 2. Using double optocoupler isolation, strong drive capability, stable performance, trigger current 5mA, 3. Each channel of the module can be triggered by jumper high or low level, 4. Fault-tolerant design, even if the control line is broken, the relay will not move, 5. Power indicator green), 1 relay status indicators red). 6. User-friendly interface design, all interfaces can be directly connected through the wiring terminals, very convenient. Module interface: 1. DC+: Connect to the positive pole of the power supply voltage is relay 5V). 2. DC-Connect to the negative pole of the power supply. 3. IN: The relay can be controlled by high or low level. Relay output: 1. NO: Relay normally open interface, before the relay is vacant, it will be shorted to COM after picking up. 2. COM: Relay Common Interface. 3. NC: Normally closed relay interface.
