This 8 channel 5V relay control board module with optocoupler modules is compliant with international safety standards, control and load areas isolation trenches it has a single relay a genuine.

The inputs of the 8 Channel 5V Relay Moduleare isolated to protect any delicate control circuitry.

It can be used as a single chip module for appliance control and work with both DC or AC signals where you can control the 220V AC load.

This module comes with a Guide rail situated on the backside of it so we can adjust the module to a superior location.

Note: On the high level and low level-triggered mode, who do not understand, have a look

• High-level trigger refers to the signal voltage between input and trigger, can be understood as a signal input with VCC cathode short-circuit triggered away;
• Low-level trigger refers to the signal voltage between the input terminal and Earth OV trigger, can be understood as a signal input terminal and the GND negative electrode short circuit triggered is a way 8-channel relay module connection.
