Module description:
1. This module complies with international safety standards, and the control area and the load area have isolation slots;

2, This 8 channel 12V relay has both optical and magnetic isolation, providing a lot of protection to the inputs from electrical faults on the outputs.

3. Adopt relay control;

4, With relay action indication, the suction is bright, the disconnection is not bright;

5. When the signal input terminal has a low level signal, the common terminal and the normally open terminal will be turned on;

6, the relay can directly control various equipment and load;

7, there are 8 normally open and 8 normally closed contacts, Can be selected by jumper relay and TTL or ground;

8.LED indicates its working status. Red refers to errors.

9.Transistor drive to increase the relay coil control pins high impedance

10.The control pin has a pull-down circuit to prevent malfunction relay vacant
