OMRON SDV-FH6 461345H SDV Series Voltage Monitoring Relay, AC100/110V

Overview The OMRON SDV-FH6 (461345H) is a SDV‑FH series single-action voltage sensor (voltage monitoring relay) from Omron. It supports overvoltage and undervoltage detection, selectable for AC/DC signals, widely stocked as spare for power panel monitoring and machine protection circuits.

Features This SDV-FH6 unit uses DIP switch configuration for overvoltage / undervoltage mode selection. The SDV-FH6 461345H is rated for AC100/110V control power supply, with adjustable operating and reset threshold, dry contact relay output and LED status indicator. It can pair with SDV-SH shunt for current monitoring and is DIN rail mountable.

Specs Model: SDV-FH6, Part No.:461345H Series: Omron SDV Voltage Sensor Type: Voltage monitoring relay Control supply: 100/110V AC Input signal: AC/DC selectable, 10~300V range Mounting: DIN rail Protection class: IP20 Certifications: CE, UL Product status: obsolete industrial spare

Principle The module continuously samples the monitored voltage. When the voltage exceeds or drops below the preset threshold, the internal relay switches contact state to trigger alarm or protection interlock. It supports on-site calibration of pickup and reset values.

Applications The SDV-FH6 461345H is widely deployed in thermal power auxiliary panels, conveyor control cabinets and factory motor protection circuits. It is used for overvoltage and undervoltage monitoring and protection.
