1 Channel 12V 30A Relay Module with Optocoupler and Guide Rail

1 Channel 12V 30A Relay Module with Optocoupler and Guide Rail

This module is a 1-channel 12V 30A relay control board with optocoupler modules. It meets international safety standards and has isolation trenches between the control and load areas. It uses a genuine single relay.

The inputs of the 1-channel 12V 30A Relay Module are isolated to protect the control circuitry from damage.

The module has indicators for power supply and relay status. When the input signal is on, the relay connects the common terminal and the normally open terminal. The module can control appliances with both DC and AC signals, up to 220V AC.

The module is compatible with various microcontrollers, such as Arduino, AVR, PIC, ARM, etc.

The module has a guide rail on the backside, which allows it to be mounted on a suitable location.

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.
