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

Description 1 Solid state relay 240V 2A output with resistance fuse 240V 2A 2 Input power 5V3 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 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 supplyCH1 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 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 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 Electrical parameters Voltage version Quiescent current Operating current Trigger voltage
