The DEIF TAS-311DG is a selectable AC transducer designed to convert AC voltage signals into a precise 4–20mA analogue output, making it a critical signal conditioning component within marine control and power monitoring systems. Configured for star (L-N) coupling with a 0–120V AC input range and a 24VDC supply, this transducer delivers reliable measurement and conversion of AC electrical parameters for use across generator management, switchboard monitoring, and automated control applications onboard. As part of a Marine Control System, it enables accurate data transmission to PLCs, controllers, and display units, supporting safe and efficient vessel power management.
Key Features
✓ Converts 0.0–120.0V AC (L-N) input to a 4.0–20.0mA analogue output signal, with an extended limit range of 4.0–21.5mA for boundary detection and fault indication.
✓ Rated to 600V CAT III, confirming suitability for measurement in distribution-level electrical environments subject to transient overvoltage conditions typical in marine power systems.
✓ Operates on a 24VDC supply with a maximum load of less than 500 ohms, making it compatible with standard marine automation loop-powered instrumentation configurations.
✓ Star (L-N) coupling configuration suits three-phase AC systems where line-to-neutral voltage monitoring is required, such as generator output or bus voltage measurement on marine switchboards.
✓ Compact transducer format typical of DEIF instrumentation supports panel-mount or DIN rail installation in control cabinets; confirm mounting arrangement and enclosure compatibility with your specific installation prior to fitment.
Marine Applications
✓ Generator management and power monitoring panels on merchant vessels, offshore platforms, and yachts where AC voltage signal conversion is required for automation and control.
✓ Switchboard instrumentation on cargo ships, bulk carriers, and tankers where accurate line-to-neutral voltage measurement feeds into alarm, protection, or load-sharing systems.
✓ Integrated with DEIF generator controllers and power management systems (PMS) to provide analogue feedback for automated control loops and operator display units.
✓ Engine room automation systems on ferries, OSVs, and naval auxiliaries where reliable analogue signal transmission from AC sources to PLCs or SCADA systems is essential.
✓ Retrofit and upgrade applications where an existing AC transducer requires like-for-like replacement to restore accurate voltage monitoring within a certified marine control system.
Why Marine Engineers Choose
Marine engineers specify the DEIF TAS-311DG for its well-established signal accuracy, straightforward 4–20mA loop integration, and its 600V CAT III rating, which provides confidence in demanding shipboard electrical environments where reliable voltage measurement directly supports safe power system operation.
Ideal For
Merchant vessels, offshore support vessels, platform supply vessels, ferries, bulk carriers, tankers, and any commercial or industrial marine application requiring accurate AC voltage transduction within a generator control or power management system.
Technical Support & Compliance
Remote troubleshooting, commissioning guidance, onboard support coordination, and integration assistance are available to help ensure correct installation and loop calibration within your existing marine control system. Repair and retrofit advisory services are also available subject to confirmation of the installation scope and system architecture. To confirm compatibility and suitability for your application, buyers are encouraged to share nameplate photographs, the full part number (100089925.110), any relevant system drawings or wiring diagrams, the model and software version of the associated controller or panel, and vessel name or IMO number where applicable. All compatibility and fitment assessments are subject to confirmation based on the information provided.
