Description

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

It is an OMRON 5V 240V solid state relay 2A, output with resistance type fuse 240V 2A. The input control signal voltage for the relay module is: (the state of the 0-2.5V low-level relay OFF; the state of the 3-5V high-level relay ON).

Low-level trigger refers to the signal triggering voltage between the end and the negative electrode of the power supply is OV, or trigger terminal voltage lower voltage than the positive power supply voltage, low to can trigger, make the relay, is usually the cathode of the power supply and the triggering end of a trigger mode connection, so that the relay is attracted.

It has the blue KF301 terminal is connected to the line of control.

Principle of Work:

The module uses high-side current sensing to measure current flow through a load or battery by detecting the voltage drop across a small internal resistor. The MAX471 includes a built-in 35mΩ sense resistor, while the MAX472 supports external resistors for higher currents. An internal amplifier boosts the voltage drop, converting it into a proportional output voltage. A single external resistor can be used for ground-referenced voltage conversion. The open-collector SIGN output indicates current direction, helping to determine charging or discharging states. Operating between 3V-36V, the MAX471 measures up to 3A, while the MAX472 supports higher currents.
