Module Description.

1, the module meets international safety standards, the control area and the load area has an isolation slot;

2, using double-sided FR-4 circuit board design, high-end SMD technology production;

4, with relay action indication, absorb bright, disconnect not bright;

5, the signal input has a low-level signal, the public end and the normally open end will conduct;

6, the relay can directly control a variety of devices and loads;

7, there are 8 normally open and 8 normally closed contacts;

8, blue KF301 terminals to connect the control line more convenient.

9, module size: 138m * 56mm * 18.5mm (L * W * H), net weight: 120g

10, with 4 fixed bolt holes, hole 3.1mm, spacing 131mm * 49.5mm

11、The finished product passes 100% function test and stability test.

Two module interface.

1, VCC: connected to the 5V 12V 24V power supply positive (according to their own choice of voltage)

2, GND: connected to the 5V 12V 24V power supply negative (according to their own choice of voltage)

3、IN1-IN8:Signal trigger terminal, low-level effective

Relay output: 12-wire interface, all interfaces can be directly connected to the line out, user-friendly

1、NO1--NO8：Normally open relay interface, the relay is suspended before the absorption, and shorted to COM after the absorption.

2、COM1---COM8 relay common interface
