16 way 12V relay module relay control board with optocoupler protection strip LM2576

Product 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 driver low level is valid.

2. Can be used as a microcontroller development board module, can be controlled by writer electronics, and can also be used as a PLC extension output.

Product Features

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

2. Adopting industry standards Quality isolation optocoupler with strong anti-interference ability and stable performance; The triggering current only requires 3mA.

3. Route 1-16 is optional Open/close, or any path.

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

5. Each relay's common terminal COM is DU based, making it convenient for users to access different signals. Each relay is equipped with normally closed and normally open ports.

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

7. The interface design is user-friendly, and all interfaces can be directly wired out through terminal blocks, which is very convenient.

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

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

Electrical parameters

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 12V voltage;

2. The power supply should be connected in reverse according to the wiring diagram requirements;

3. The use of LM2596S voltage reducing chip in the product causes slight heating, which is a normal phenomenon. The relay also experiences normal heating after long-term operation, 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 may have a certain impact on the product life.
