Features

This 1-channel 5V 30A 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 1 Channel 5V 30A Relay Module are isolated to protect any delicate control circuitry. The power supply and relay instructions, lit, a disconnect are off. The input signal, signal, common Terminal and start conducting. 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.

Note: On the high-level and low-level-triggered mode, If You do not understand Please Check the Below Points. A high-level trigger refers to the signal voltage between input and trigger, which can be understood as a signal input with a VCC cathode short-circuit triggered away. Low-level trigger refers to the signal voltage between the input terminal and Earth OV trigger, which can be understood as a signal input terminal and the GND negative electrode short circuit triggered is a way 1-channel relay module connection.
