【2-3 days delivery】 3.3V 5V 12V 24V 1 Channel Relay Module High and low Level Trigger Relay Board

Module description:1. The module adopts genuine quality relay, the maximum load of the normally open interface: AC 250V 10A, DC 30V 10A;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 convenientModule 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 supply3 .IN: The relay can be controlled by high or low levelRelay output:1. NO: Relay normally open interface, before the relay is vacant, it will be shorted to COM after picking up2. COM: Relay Common Interface3. NC: Normally closed relay interface. Before the relay is closed, it is short-circuited with COM.High and low level trigger selection:1. S1 is the high and low level trigger selection of relay 1;2. When com is shorted to low, the corresponding relay is a low level trigger. When com is shorted to high, it is a high level triggerNote:1.Due to the different monitor and light effect, the actual color of the item might be slightly different from the color which is showed on the pictures.2.Please forgive 1 cm 0.39 -3 cm 1.18 measuring deviation due to manual measurement.
