The Omron S8M-CP04 is a DIN-rail mounted multicircuit protector from the S8M series. It combines overcurrent, overtemperature, overvoltage, and undervoltage protection in a single unit, powered by a 24VDC supply. The trip range of 0.5mA ~ 4A means it can protect sensitive control circuits drawing as little as half a milliamp, all the way up to a 4A load. The voltage trip window of 18.0 ~ 28.8VDC means it will drop the load if the supply sags below 18V or rises above 28.8V — useful for catching a failing power supply before it cooks the downstream electronics.
