3.3V 5V 12V 24V 1 Channel Relay Module High and low Level Trigger Dual Optocoupler Isolation Relay Module

Reference:

In stock

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. The module operating voltage is 5V;

4. Each channel of the module can be triggered by jumper high or low level;

5. Fault-tolerant design, even if the control line is broken, the relay will not move;

6. Power indicator (green), 1 relay status indicators (red)

7. 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. 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 trigger.
