Tips:

This module has 12V

8 relay output modules, relay output contacts 250V 10A. Input IN1, IN2, IN3, IN4, IN5, IN6, IN7, IN8 signal lines are active low. VCC, GND power input terminal, the relay power input terminal JD-VCC can be powered separately.

use:

1. Support all MCU control.

2. Industrial field;

3. PLC control

4. Smart home control;

Features:

Using high current relay, AC250V 10A DC30V 10A

Independent wiring of the contact part, safe and reliable

Standard interface, can be extended on various development boards

With fixing screw holes for easy installation

Suitable for various platforms such as 51/AVR/AVR/ARM

1. This module complies with international safety standards, and there are isolation slots between the control area and the load area;

2. It adopts double-sided FR-4 circuit board design and high-end chip production technology;

3. Use Songle relay control;

4. With relay action indication, it is bright when it is on, but not when it is off;

5. When there is a low-level signal at the signal input terminal, the common terminal and the normally open terminal will conduct;

6. The relay can directly control various equipment and loads;

7. There are 8 normally open and 8 normally closed contacts;

8. The blue KF301 terminal is more convenient to connect to the control line.

9. Module size: 138m * 56mm* 18.5mm (length * width * height), net weight: 120g

10. There are 4 fixing bolt holes, the hole is 3.1mm, and the spacing is 131mm*49.5mm

11. The finished product passes the function test and stability test

Module interface:

1. VCC: Connect the positive pole of the 12V power supply

2. GND: connect to the negative pole of the 12V power supply

3. IN1-IN8: signal trigger terminal, low level effective

Relay output terminal: There are 12-wire interface, all interfaces can be directly connected to lead, which is convenient for users to use

1. NO1--NO8: Relay normally open interface, the relay is suspended before it is closed, and shorted to COM after it is closed

2. COM1--COM8 relay common interface
