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

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.

Operational Guide:

• High-level trigger refers to the signal voltage between input and trigger, and 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, 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.
