SDV-FH4

Overview of Omron SDV-FH4

The Omron SDV-FH4 is a voltage sensor designed for overvoltage or undervoltage detection applications, supporting a control power supply voltage of DC 100/110 V. It features a compact and slim profile with high-density mounting to save space in control panels. The sensor has a selectable operating voltage range from 10 to 300 V (either AC or DC input) and includes a single-function overvoltage or undervoltage detection capability. It is equipped with an SPDT control output and supports various reset and operating values adjustable within specified ranges.
