DC 6-24V 1-Channel Bistable Self-Locking Relay Module – Low-Pulse Trigger

The Gaqqee IO25B01 Bistable Self-Locking Relay Module is a compact, energy-efficient single-channel relay designed for a wide range of electronics projects. With a wide operating voltage range of DC 6–24V and ultra-low standby current of just 1μA, this module is the perfect choice for automotive electronics, smart home systems, industrial equipment, MCU development boards, and more.

Unlike traditional relay modules, the bistable (self-locking) design means the relay holds its last switched state even when trigger power is removed — no continuous power draw required to maintain position. A simple low-pulse trigger signal is all it takes to toggle the relay, making it ideal for power-sensitive applications.

Made in Mainland China.

Frequently Asked Questions

Q: What does "bistable" or "self-locking" mean in this relay module?

A: A bistable relay module maintains its switched state (either ON or OFF) after the trigger pulse is removed, without requiring continuous power to hold the position. Each low-pulse signal on the T pin toggles the relay between states, making it extremely energy efficient and ideal for battery-powered or automotive applications.

Q: What microcontrollers or systems are compatible with this relay module?

A: The Gaqqee DC 6-24V bistable relay module is compatible with a wide range of systems including Arduino, Raspberry Pi, STM32, ESP8266/ESP32, and other 3.3V–5V MCU development boards, as well as 12V and 24V automotive electronics systems.

Q: What is the maximum load this relay module can handle?

A: This self-locking relay module supports a maximum load of AC 250V/10A for AC circuits and DC 30V/10A for DC circuits, making it suitable for controlling a wide variety of household, automotive, and industrial electrical loads.

Q: How do I trigger the relay to switch states?

A: Simply send a short low-pulse signal to the T (trigger) pin. Each pulse toggles the relay between its ON and OFF states. The relay holds its position after the pulse ends — no sustained signal is needed.
