Control Equipment The single-channel relay module employs a high-quality DC5V relay and SMD optical isolator, supporting high/low level triggering and widely used for controlling various AC/DC and high-current devices. Load Range For the normally open state, the maximum load is < AC 250V/10A and < DC 30V/10A. The trigger current of the optical isolator is 5mA. Fault-Tolerant Design The relay will not operate even if the control line is disconnected, ensuring safety and stability. Universal Interface Equipped with screw terminal blocks and fixing bolt holes (diameter: 3.1 mm) on both sides for easy installation. High Compatibility The relay module can be directly controlled by 5V logic signals from microcontrollers such as 8051, AVR, PIC, DSP, ARM, Raspberry Pi, MSP430, and TTL logic.
