5V Relay 2 Channel SSR Low Level Solid State Relay Module 250V 2A with Fuse

1. Solid state relay 240V 2A, output with resistance fuse 240V 2A.

2. Input power: 5V

3. Input control signal voltage: (0-2.5V state low level relay ON)(3.3-5V state high level relay OFF)

4. It is more convenient to have 2.54CM pin and blue KF301 terminal to connect the control line.

DC+: Connect the positive pole of the power supply (powered by the relay voltage)

DC-: connected to the negative pole of the power supply

CH1: 1 relay module signal trigger terminal (low level trigger is valid)

CH2: 2-way relay module signal trigger terminal (low level trigger is valid)

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 triggering method 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 the 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.

Voltage version Quiescent current Operating current Trigger voltage Trigger current

 1 way 5V 0mA 13.8mA 0-2V 2mA

 2 way 5V 0mA 26.8mA 0-2V 2mA

Power supply of the module: the power supply must be DC, and the voltage should match the voltage of the relay.
