1 Channel 5V Relay Module For Arduino

Features: Input connection: DC+ is positive power supply, DC- is negative power supply and IN means control the pick up of replay by low level or high level Output connection: NO(normally open): The relay is normally open interface, the relay is suspended before it is closed, and it is shorted to COM after it is closed. COM(common): The relay common interface. NC(normally closed): Normally closed interface of the relay, the relay is short-connected with COM before it is closed, and it is suspended after being closed. LED indicator light: The power indicator is green, and the indicator of relay status is red, making them clear at a glance. High or low level trigger select: When the jumper is connected to L, it triggers at low level, and when connected with H, it triggers at high level Specifications: Material: circuit board Control signal: TTL Rated load: AC125~250v/ 10A, DC28~30v/ 10A Max. switch voltage: 250VAC, 30v Trigger voltage: 0-1.5v (low); 3-5v (high) Trigger current: 5mA Max current: 190mA Fixing bolt hole: hole diameter is 3.1 mm/ 0.12 inches, the pitch is 44.5 x 20.5 mm/ 1.75 x 0.81 inches Size: 50 x 26 x 18.5 mm/ 1.97 x 1.02 x 0.73 inches
