16 Way Relay Module 5V 12V Control Board with Optocoupler Protection and LM2596 Power RelayItem NO.: 16WAY5V12V

16 Way Relay Module 5V 12V Control Board

Application:

1. 12V relay contact capacity 10A 250V, with optocoupler protection. The onboard power module does not require an external power supply. I/O port drive low level effective.

2. Can be used as a microcontroller development board module, can be controlled by a writer's computer, or can be used as a PLC expansion output.

Module features:

1. Control signal voltage range: trigger signal is low-level 0-2V; The high-level voltage cannot exceed 5V.

2. Adopting isolation optocoupler, with strong anti-interference ability and stable performance; The triggering current only needs 3mA.

3. 1-16 channels can be turned on/off at will, or any channel.

4. Output form: Directly connected to AC 220V 10A or DC30V 10A load.

5. Each relay's common COM is independent, making it convenient for users to access different signals. Each relay has normally closed and normally open ports.

6. Each relay is equipped with an action indicator light, which turns on when it is engaged and off when it is disconnected.

7. The interface design is user-friendly, and all interfaces can be directly connected and led out through wiring terminals, which is very convenient.

8. Equipped with 4 fixed bolt holes for easy installation.

Electrical parameters:

Power supply voltage: 5V 12V (DC)

Power supply current: greater than 200mA

Each relay can load: 250V 10A (AC) or 30V 10A (DC)

Product Instructions:

1. The power supply should meet the usage range, with a DC of 12V;

2. The power supply should comply with the wiring diagram requirements and should not be connected in reverse;

3. The product uses the LM2596S step-down chip to generate slight heat, which is a normal phenomenon. The relay also has normal heat when working for a long time, which is a normal phenomenon;

4. The load power should leave a certain margin for the relay load, and avoid environments with high power (around 2000W) and long-term operation, which will have a certain impact on the product life.
