COMPATIBLE WITH ARDUINO 12V/30A CH RELAY MODULE WITH N/O AND N/C CONTACTS WITH OPTO ISOLATED I/P Discontinued Specifications, Prices & Availability may change without notice. Images are for illustration purposes only. E&OE Features The module adopts genuine high quality 30A relay, the maximum load of normally open interface: AC 250V/30A, DC 30V/30A. Using chip optocoupler isolation, strong driving ability, stable performance; trigger current 5mA. Module operating voltage 12V. The module can be triggered by a jumper to set a high or low level. The interface design is user-friendly, and all interfaces can be directly connected through the terminal block, which is very convenient. Module size: 72 x 40 x 24mm (Length * Width * Height), with module holder: 86 x 43 x 45mm Product net weight: 46g 4 fixing bolt holes, hole 3.1mm, spacing 44.5 x 27.5mm Specifications Relay : 12V Quiescent Current : 5mA Maximum current : 190mA Trigger current : 2-4mA Module interface description: DC+: Module DC power supply positive (trigger terminal voltage positive) DC-: Module DC power supply negative (trigger terminal voltage negative) IN: Signal trigger terminal (default trigger voltage is the same as power supply) High/low level trigger mode selection, when the jumper is connected with the L terminal, the IN terminal is low level trigger, and when connected to the H terminal, it is triggered high level. Normally closed terminal (NC): relay normally closed terminal Common (COM): Relay Common Normally open (NO): The relay is normally open Package includes: 1 x Realy Module
