Description

12V 1-Channel Relay Module with Optocoupler High Level Triger for ArduinoProduct introduction:1. this module conform international safety standard, the isolation groove between control areas and load area;2. with optical coupling isolation, triggering more reliable, more stable;3. the double FR-4 circuit board design;4. have power and relay operation instructions.The LED will be lit when relay on;5. signal input with a high level signal, the common pin;6. relay can directly control all kinds of equipment and load;7. one normally open pin and a normally closed pin;8. blue KF301 terminal, more convenient;9. module size: 53x18x18.5mm;Module interface:Input part:VCC:connect to power positive (according to the relay voltage range)GND: connect to power negativeIN: relay module trigger pin (high level trigger)Output part:Normally Opened (NO) : normally open pin of relay. NO pin is not connect to COM pin when relay off.NO pin is connect to COM pin when relay on;Common pin (COM) : Common pin of the relay;Normally closed (NC) : normally close pin of relay.NC pin is connect to COM pin when relay off.NC pin is not connect to COM pin when relay on;Electrical parameters:Voltage version:12VThe static current:5.5mAWorking current:42mATrigger voltage:4-9VTrigger current:3mA
