16-channel 12V Relay Module Interface Control Board with Optocoupler Protection

1、Control signal voltage range: The trigger signal is low level 0-2V; the high level voltage cannot exceed 12V.

2、Adopting the industry's top quality isolated optocoupler, it has strong anti-interference ability and stable performance; the trigger current only needs 3mA.

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

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

5、Each relay common terminal COM is independent, which is convenient for users to access different signals. Each relay has a normally closed and normally open port.

Features:

1. Control signal voltage range: The trigger signal is low level 0-2V; the high level voltage cannot exceed 12V.

2. Adopting the industry's top quality isolated optocoupler, it has strong anti-interference ability and stable performance; the trigger current only needs 3mA.

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

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

5. Each relay common terminal COM is independent, which is convenient for users to access different signals. Each relay has a normally closed and normally open port.

6. Each relay has an action indicator, which is illuminated and turned off.

7. The interface design is user-friendly, and all interfaces can be directly connected through the terminal block, which is very convenient.

8. There are 4 fixing bolt holes for easy installation.

9. PCB board size: 180MM (L) * 90MM (W) * 20MM (H)

11. Can be used as a microcontroller development board module, can be used as home appliance control, can also be used as PLC expansion output.

Specification:

Condition: 100% Brand New

Item Type: Relay Module

Supply Voltage: DC 12V

Package List:

1 * Relay Module

Product Instructions:

1. The power supply should meet the scope of use, DC 12V;

2. The power supply is required according to the wiring diagram and cannot be reversed;

3. The product uses LM2596S step-down chip with slight heat, which is a normal phenomenon. The relay has normal heating phenomenon for a long time, which is a normal phenomenon;

4. The load power should have a certain margin for the relay load. Avoid high power (about 2000W) and work for a long time, which will have a certain impact on product life.
