Description

The BDD 12V 1 Channel High/Low Trigger Relay Module is a compact, opto-isolated relay board designed for safely controlling high-voltage and high-current loads from microcontrollers, PLCs, automation systems, and industrial controllers. Supporting both high-level and low-level trigger inputs, this versatile module is suitable for a wide variety of switching applications.

Powered from a 12V DC supply, the onboard relay can switch loads up to 10A at 250VAC or 10A at 30VDC. An integrated optocoupler isolation circuit helps protect the control electronics from electrical noise and interference, improving system reliability. The module also features a KF301 screw terminal for quick, secure wiring of power and load connections.

Ideal for home automation, industrial control, robotics, alarm systems, and DIY electronics, this relay module provides dependable switching performance in a compact form factor.

Warning: This module can switch mains voltages. Installation and wiring should only be performed by qualified personnel using appropriate electrical safety practices.
