Product Description

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 3.3V;

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), 6 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 (Pressure relay 3.3V)

2. DC-: Connect to the negative pole of the power supply

3. IN1-IN8: According to the setting of each channel, the corresponding relay can be controlled by high or low level.

Relay output:

1. NO1-NO8: Normal open interface of the relay. Before the relay is closed, it is left unconnected. After picking up, it is shorted to COM.

2. COM1-COM8: Relay Common Interface

3. NC1-NC8: Normally closed relay interface. Before the relay is closed, it is short-circuited with COM.

High and low level trigger selection:

1. S1-S8 is the high and low level trigger selection for Relay 1-8 channel;

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.
