5V 1 Ch 30A Relay Module

• Trigger Voltage: 5VDC 
• Switching Voltage: 250VAC@30A; 30VDC@30A
• The module can be set high level or low-level trigger by the jumper

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.

Features :

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. 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.
