5pcs BESTEP 1 Channel 5V Low Level Solid State Relay Module With Fuse 250V2A For Auduino

Description: 1. 5V solid state relay 240V 2A, output with resistance fuse 240V 2A. 2. Size: 25*34*25 (length * width * height) Net weight: 13g 3. Input power: 5V DC (160MA) 4. Input control signal voltage: (0-1.5V state low level relay ON) (2.5-5V state high level relay OFF) 5. The blue KF301 terminal is more convenient to connect to the control line. Module interface: Input section: DC+: Connect the positive pole of the power supply (powered by the relay voltage) DC-: Connected to the negative pole of the power supply CH: Relay module signal trigger terminal (low level trigger is valid) High and low meaning: High-level triggering means that there is a forward voltage between the signal trigger terminal (IN) and the negative pole of the power supply. Usually, a positive trigger is used to connect the positive pole of the power supply to the trigger terminal. When the trigger terminal has a positive voltage or triggers at voltage, the relay pulls in. Low-level triggering means that the voltage between the signal trigger terminal and the negative pole of the power supply is OV, or the voltage at the trigger terminal is lower than the voltage of the positive pole of the power supply. When the voltage is low enough to trigger, the relay is pulled in, usually A triggering method in which the negative pole of the power supply is connected to the trigger terminal, so that the relay is attracted. Electrical parameters: Voltage: 5V Quiescent current: 0mA Operating current: 12.5mA Trigger voltage: 0-1.5V Trigger current: 2mA Module power supply: The power supply must be DC, and the voltage should match the voltage of the relay. Package includes: 5 x 5V Relay Module
