1-Channel 24V Relay Module Active Low Trigger

1-Channel 24V Relay Module Active Low Trigger

The 1-Channel 24V Relay Module (Active Low) provides reliable switching control for one load using a 24V DC low-level trigger signal. The relay activates when the input pin receives a low logic level, making it compatible with controllers and circuits configured for active low operation.

It supports AC loads up to 250V/10A and DC loads up to 30V/10A, ensuring versatile operation for appliances, motors, pumps, and other electrical devices. Integrated opto-isolation ensures electrical separation between the control side and the load, while flyback diodes protect sensitive control circuits from relay coil voltage spikes. This module works with Arduino, ESP32, Raspberry Pi, PLCs, and other controllers, making it suitable for automation systems, IoT projects, industrial setups, and prototyping environments where a single reliable switching channel is needed.
