DC 5V 30A High Power 1-Channel Relay Module

The DC 5V 30A High Power 1-Channel Relay Module is designed for controlling high-current electrical devices using microcontrollers such as Arduino, Raspberry Pi, or other 5V logic systems. It features a high-quality relay capable of switching up to 30A at 250V AC or 30V DC. The module includes an optocoupler isolation circuit for improved stability and protection, reducing interference from the control side. With onboard indicator LEDs and screw terminals for secure wiring, this module is ideal for home automation, industrial control, and high-power switching applications. 5V 30A 1-Channel Relay Module with Optocoupler H/L Level Triger Module description: 30A relay module, normally open interface maximum load: AC 250V/30A, DV 30V/30A Optical coupling isolation, driving ability is strong, stable performance;Trigger current is 5mA Module can be set high level or low level trigger by the jumper Power indicator light (green), relay status indicator light (red) Module Size:50mm*33mm*24mm Technical parameters: Voltage version:5V The static current:5mA Working current:190mA Trigger current:2-4mA Module interface specifications: DC+ : DC power supply positive pole DC- :DC power supply negative pole IN : signal triggering pin JD+ : relay control voltage positive JD- : relay control voltage negative DC+ and JD+ shorted by jumper cap, DC- and JD- shorted with jumper cap, it is the same voltage between trigger terminal and relay control terminal High and low level trigger mode selection.Jumper and L pin connection, IN pin is low level triggerJumper and H pin connection, IN pin is high level trigger Normally closed pin (NC) : relay normally closed pin Common pin (COM) : relay common pin Normally opened pin (NO) : relay normally opened pin Rated current of the interface is 16A
