5V 30A 1-Channel Relay Module with Optocoupler H/L Level Triger for Arduino Module description: 1. 30A relay module, normally open interface maximum load: AC 250V/30A, DV 30V/30A; 2. Optical coupling isolation, driving ability is strong, stable performance;Trigger current is 5mA; 3. Module can be set high level or low level trigger by the jumper; 4. Power indicator light (green), relay status indicator light (red); 5. Module Size:50mm*33mm*24mm; Technical parameters: Voltage version:5V The static current:5mA Working current:190mA Trigger current:2-4mA Module interface specifications: 1. DC+ : DC power supply positive pole 2. DC- :DC power supply negative pole 3. IN : signal triggering pin 4. JD+ : relay control voltage positive 5. JD- : relay control voltage negative 6. 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 7. 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 8. Normally closed pin (NC) : relay normally closed pin 9. Common pin (COM) : relay common pin 10. Normally opened pin (NO) : relay normally opened pin 11. Rated current of the interface is 16A
