Fafeicy 4 Channel Self Locking Relay Module Low Level 5V Relay Board with and Stability for MCU Control

[STRONG & RELIABLE SELF-LOCKING DESIGN] This advanced 4-channel relay module features a bistable self-locking mechanism. Once triggered by a brief low pulse signal, it switches and maintains its state without continuous power, providing exceptional reliability and energy efficiency for your long-term automation and control projects. [VERSATILE LOW-LEVEL CONTROL] Engineered for seamless microcontroller integration, this module operates on a low-level logic, making it perfectly compatible with popular MCUs like , , and A simple, momentary low pulse (0.2-2 seconds) toggles each relay, offering precise and safe control for makers and engineers. [HIGH POWER HANDLING & MULTI-CHANNEL FLEXIBILITY] With four independent relays, this board can control multiple circuits simultaneously. Each relay supports a substantial load of up to 10A at 250V AC or 30V DC, allowing you to safely manage lights, motors, appliances, and other high-power devices from a single, compact module. [ & SIMPLE INSTALLATION] Built with industrial-grade components and adhering to strict quality control, this relay module ensures strong stability and noise resistance. It comes with clearly labeled terminals (V, G, T, NO, COM, NC) and standard mounting holes, enabling a quick and hassle-free setup without complicated wiring or configuration. [RIGOROUSLY TESTED FOR CONFIDENCE] Every unit undergoes multiple inspections and performance tests before leaving the factory. The durable construction and quality-assured components guarantee long-term, trouble-free operation, so you can integrate this module into your home automation, IoT, or industrial control systems with complete confidence.
