5V Low Level Solid State Relay Module with Fuse Solid State Relay 250V 2ASize: 25 * 34 * 25 (L * W * H) Net Weight: 13gInput : 5V DC (160MA)The input control signal voltage:(0-1.5V state low level relay ON) (2.5-5V state high level relay OFF)Blue KF301 terminal access control line more convenient.Color:blackMaterial:MetalModule Interface:Input section:DC +: Connect the supply positive (according to the relay voltage)DC-: Connect the supply negative: relay module signal trigger terminal (low level trigger active)High and low meaning:High-level trigger refers to the signal trigger side (IN) and the supply there is a positive voltage between the positive, usually with the of the positive and trigger connected to a trigger mode, when the trigger side has a positive voltage or trigger Voltage, the relay is pulled.Low-level trigger refers to the signal trigger terminal and the supply negative voltage between the OV, or the trigger side of the voltage than the supply voltage is lower, low to trigger the voltage, so that the relay pull, usually The negative side of the supply is connected to the trigger terminal and is triggered by the relay.Electrical parameters:Voltage Version Quiescent Current Operating Current Trigger Voltage Trigger Current5V 0mA 12.5mA 0-1.5V 2mAproduct manual:Module supply: the must be DC, the voltage and the relay voltage to matchPackage Includes : 1 x Solid State Relay ModuleNote: Light and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
