  • 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
  • The module can be set high-level or low-level trigger by the jumper
  • Power indicator light (green), relay status indicator light (red)
  • Module Size: 50*33*24 mm

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
