30A relay module, normally open interface maximum load: AC 250V/30A, DV 30V/30AOptical coupling isolation, driving ability is strong, stable performanceTrigger current is 5mAThe module can be set high level or low-level trigger by the jumper.DC : DC power supply positive poleDC-: DC power supply negative poleIN : signal triggering pinJD : relay control voltage positiveJD-: relay control voltage negativeDC and JD shorted by jumper cap, DC- and JD- shorted with jumper cap, it is the same voltage between trigger terminal and relay control terminalHigh 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 a high-level triggerNormally closed pin (NC): relay normally closed pinCommon pin (COM): relay common pinNormally opened pin (NO): relay normally opened pin SKU: EAP-000099 Categories: DIY Items, Electronic Parts, Module, Relay Module Tag: 1 Channel Relay Module
