1 Channel Relay Module, 30A with Optocoupler, Isolation 24V Supports, High and Low Triger

This 1 channel 24V 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 1 Channel 24V 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.

A wide range of microcontrollers such as Arduino, AVR, PIC, ARM and so on can control it.

Note: On the high level and low level-triggered mode, friends 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  1-channel relay module connection.
