Five digit frequency accuracy
The five digit readout shows frequency to two decimal places, giving panel operators a precise, at a glance value instead of a rounded estimate.
Digital Display
Frequency Display 100mm LED
T-FDU-300-100-5D
A standalone 100mm RED LED frequency display that gives panel operators a precise, five digit, second by second reading of supply frequency, direct from a 230V AC signal, without routing through a network time source.
Five digit readout, 0-50 Hz standard range
100mm RED LED digits for long distance viewing
IP55 weatherproof as standard, IP66 available
Universal 90-260V AC/DC power input
Key Advantages
Built for clear frequency readings on the plant floor
Seven reasons the T-FDU-300-100-5D holds up in real panel and switchyard conditions.
100 mm LED digits for distance viewing
Large format 100 mm RED seven segment digits stay legible from across a control room, switchyard aisle, or generator hall, not just from arm's length.
Non glare, wide angle viewing
A red transparent filter overlay widens the usable viewing angle and cuts glare, so the reading stays clear under bright panel lighting or direct sunlight.
IP55 weatherproof construction
The enclosure meets IP55 protection as standard, with an IP66 variant available for outdoor or exposed installations.
Independent slave network operation
Where multiple display units share a network, the failure of one slave unit does not interrupt the display operation of any other unit on that network.
Second by second signal refresh
The readout updates every second, keeping the displayed frequency aligned with real time changes on the monitored supply.
Universal AC/DC power input
A wide 90 to 260V AC/DC input range lets the same unit run on varied site supplies without a separate power conversion step.
