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

The listing says that it can be directly driven by all microcontrollers, FALSE! I've never used a microcontroller with 12v output pins and 12v would fry nearly every microcontroller on the market. Chalk it up to yet another amazon purchase that will go into the trash due to false advertising.
