Single-channel 5V 30A Relay Module

The Songle Single-channel 5V 30A Relay Module power failure relay is a 1-channel relay module board with LED indicators, It can be controlled by microcontrollers such as Arduino, AVR, PIC, ARM any other microcontroller operating at 5V.

Tech specifications

1. Optical coupling isolation, driving ability is strong, stable performance; Trigger current is 5mA
2. The module can be set high level or low-level trigger by the jumper
3. The Rated current of the interface is 16A
4. 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.
5. 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 the high-level trigger.
