The DEIF TMF-210DG/2 is a mains frequency transducer designed to accurately measure and convert AC frequency signals into a proportional analogue voltage output. Operating across a range of 45 to 65 Hz with a midpoint at 55 Hz, it accepts a 230V AC input and delivers a 0–5–10V DC output signal suitable for feeding into monitoring, control, and automation systems. Within the marine control system category, frequency transducers of this type play a critical role in power management — providing real-time frequency data to generator control panels, synchronising units, and switchboard automation systems to ensure stable and safe electrical distribution onboard.
Key Features
✓ Measures mains frequency across a 45–65 Hz range with a 55 Hz midpoint, providing a calibrated 0–5–10V DC analogue output for direct integration with control and monitoring equipment.
✓ Accepts a 230V AC input signal and requires a 230V AC supply, with a minimum load impedance of 500 Ω on the output — specifications are as stated on the unit nameplate and confirmed in the original product data.
✓ Compatible with DEIF power management and generator control architectures; subject to confirmation based on system model, software version, and panel configuration.
✓ Designed for panel or DIN-rail mounting in switchboard and control room environments; exact enclosure dimensions and ingress protection rating should be confirmed against installation drawings.
✓ Direct replacement or retrofit for existing DEIF frequency transducer installations; compatibility with specific panels or controllers should be verified using nameplate data and system documentation prior to fitment.
Marine Applications
✓ Generator control and synchronisation panels aboard commercial vessels requiring precise mains frequency monitoring for load sharing and parallel operation.
✓ Main and emergency switchboard automation systems on cargo vessels, tankers, and offshore support vessels where frequency deviation must be detected and signalled in real time.
✓ Power management systems (PMS) integrating analogue transducer signals for centralised monitoring of generator performance and grid stability.
✓ Retrofit and upgrade projects on vessels with ageing DEIF-based control infrastructure, where the original transducer requires like-for-like replacement.
✓ Newbuild and conversion projects specifying DEIF control components as part of a standardised marine electrical and automation suite.
Why Marine Engineers Choose
The DEIF TMF-210DG/2 is valued for its straightforward analogue output interface, wide frequency measurement range suited to both 50 Hz and 60 Hz electrical networks, and its direct compatibility with DEIF power management ecosystems — making it a reliable component for both planned maintenance and emergency replacement scenarios.
Ideal For
Cargo vessels, bulk carriers, tankers, offshore support vessels, ferries, and any commercial or industrial marine application operating DEIF-based generator control or power management systems requiring mains frequency transduction.
Technical Support & Compliance
Technical assistance is available to support remote troubleshooting, onboard diagnostics, testing and commissioning, and integration of this transducer into existing or upgraded marine control systems. Retrofit and compatibility support can be provided subject to confirmation of the vessel’s existing DEIF system configuration. To confirm suitability, buyers are encouraged to share nameplate photographs, the full part number (215003.20), relevant panel or system model and version details, single-line or wiring drawings, and vessel name or IMO number where applicable. All compatibility assessments are subject to confirmation based on the information provided.
