4-Channel 5V Self-Latching Latch Relay Module, Board

【4-Channel Latching】This latching relay module is a 4-channel, 5V bistable relay board. Each channel toggles between closed and closed positions with a single low pulse or button press.
【Self-Latching Toggle】Designed as a self-latching bistable relay module, it retains the last state after triggering. Press the button again or send a 0.3-1 second low pulse to change the state.
【Electrical Specifications】Operating Voltage: 5V DC. Operating Current: 70mA for 1 relay, 140mA for 2, 210mA for 3, 280mA for 4. Standby Current: 4µA. Rated load: 250V AC 10A or 30V DC 10A.
【Clear Interface】Module ports include 5V, G, T1, T2, T3, and T4. Relay outputs include NO, COM, and NC, simplifying wiring for MCU development boards and control projects.
【Compact and Versatile】Board dimensions: 6.5 x 4.3 cm, weight: approximately 53g. Suitable for smart home, automotive electronics, motors, LEDs, emergency lighting, and toy cars.
