This is a 1-channel isolated 24V 10A relay module. The standard interface allows direct connection to microcontrollers, and it can be directly controlled by various microcontrollers such as Arduino, AVR, PIC, ARM, and DSP, making it very convenient. Equipped with a high-current relay, the maximum load is: AC250V 10A, 15A 125VAC, DC30V 10A; Photocoupler trigger current: 5mA. Reliability: Fault-tolerant design ensures the relay will not activate even if the control line breaks. Optical coupling isolation improves the reliability and stability of the trigger. Easy installation: Features screw terminal connection plates and fixing screw holes (diameter: 3.1mm) on both sides for easy installation. High/low level trigger can be selected with a jumper. Highly versatile, the input logic can be reversed with a jumper. Actual product photos are from the 9th image onwards. Please be sure to check the photos as they may differ from the description.
