1 Channel 30A relay module | 5V12V24V | with optocoupler isolation high and low level trigger for Arduino & PLC industrial control

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 Specifications:

• Voltage version: 5V/12V/24V
• The static current:5mA
• Working current:80mA
• 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 trigger upper 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
