16 Channel 5V / 12V / 24V Relay Module LM2596 With Optocoupler Protection Low Level Trigger Arduino IOT

1. Relay contact capacity 10A 250V with optocoupler protection. The onboard power supply module does not require an external power supply. The I/O port drive is active low.

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

 

Features:

1. Control signal voltage range: The trigger signal is low level 0-2V.

2. Adopting high 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: 180 x 90 x 20mm (L x W x H)

 

Electrical parameters:

Supply voltage: 5V / 12V / 24V (DC)

Supply current: Greater than 200mA
