Frequently Asked Questions
Q: What does "bistable" or "self-locking" mean for this relay module?
A: A bistable relay module has two stable states — ON and OFF. Once triggered by a low pulse, it latches into its new state and holds that position without needing continuous power. This makes the DC 6-24V bistable self-locking relay module highly energy-efficient, as it consumes only 1μA in standby.
Q: What types of projects is this flip-flop latch relay module best suited for?
A: This relay switch module is ideal for a wide variety of applications including smart home automation, LED lighting control, automotive electronics, emergency lighting systems, MCU development boards, industrial equipment switching, and toy car projects. Its wide 6-24V DC operating range makes it compatible with most common power supplies.
Q: How do I trigger the relay to change its state?
A: Simply apply a low-pulse signal to the T (trigger) pin. Each low pulse toggles the relay between its Normally Open (NO) and Normally Closed (NC) states. The module interface includes VCC (positive supply), GND (ground), and T (trigger input) for straightforward wiring.
Q: What is the maximum load this relay module can handle?
A: The relay output terminals support up to AC 250V/10A or DC 30V/10A, making it suitable for controlling moderate-duty loads such as LED strips, small motors, and standard home automation devices.
