HFD4/3-S Thin Profile Relay Module 3.3V 5V Durable Construction Compatible with STM32 51 Microcontroller for Robotics Projects

Description1. The relay supports wide voltage supply, the range is 3.3V-6V.2.The maximum load current of the controlled terminal of the relay is 2A@30V, 0.5A@220V (more than 60V, it is recommended to add an insulation protection box to prevent electric shock).3. Small size, adapted to signal switching or on-off control, signal insertion loss Operating current (VCC): quiescent current: 5uA action current: 40mATrigger mode (IO): high level triggerTrigger level (IO): high level: greater than 1.3V less than VCC low level: less than 0.5VTrigger current (IO): 1.8mAMaximum load: 2A@30VDC, 0.5A@220VACPackage quantity:1PcNote:Please allow 2%-3% differences due to manual measurement.
