The DEIF TAS-311DG is a selectable AC transducer designed to convert AC current signals into precise analogue output for monitoring and control purposes. Accepting an input range of 0.000 to 5.000A and delivering a 4.0 to 20.0mA output signal, it provides reliable, continuous electrical measurement data to onboard control and automation systems. As a core component within marine control system infrastructure, this transducer plays a critical role in ensuring accurate current sensing across generator sets, switchboards, and power management equipment — supporting safe and efficient vessel operation.
Key Features
✓ Selectable AC transducer function with a 0.000–5.000A input range and a calibrated 4.0–20.0mA analogue output, with an output limit of up to 21.5mA for fault detection compatibility.
✓ Rated for 600V CAT III environments, indicating suitability for use in distribution-level electrical panels and switchgear applications aboard commercial vessels.
✓ Operates on a 24VDC supply voltage with a maximum load impedance of less than 500 ohm, making it compatible with standard industrial and marine PLC or controller analogue input cards.
✓ Designed for integration within DEIF power management and generator control architectures, and compatible with analogue signal monitoring systems typical of marine automation installations — specific panel compatibility subject to confirmation.
✓ Suitable for panel-mounted or DIN-rail installation in protected electrical enclosures; mounting configuration and environmental rating should be confirmed against vessel-specific documentation prior to installation.
Marine Applications
✓ Generator control panels and automatic mains failure (AMF) systems aboard merchant vessels, where continuous AC current monitoring is essential for load management and fault protection.
✓ Shipboard power management systems (PMS) requiring analogue current feedback from multiple generator or bus sources to maintain load sharing and system stability.
✓ Main switchboard and distribution switchgear installations on offshore support vessels, platform supply vessels, and large yachts requiring CAT III rated instrumentation.
✓ Engine room automation and monitoring systems on cargo ships, tankers, and RoRo vessels where analogue transducer signals feed into central SCADA or alarm monitoring systems.
✓ Retrofit and upgrade projects on existing DEIF-equipped vessels where a like-for-like replacement transducer is required to restore system integrity and measurement accuracy.
Why Marine Engineers Choose
The DEIF TAS-311DG is a well-regarded component in marine power monitoring applications, valued for its accurate analogue signal conversion, straightforward integration with standard control inputs, and its CAT III voltage rating — all of which contribute to reliable long-term performance in demanding shipboard electrical environments.
Ideal For
Merchant vessels, offshore support vessels, platform supply vessels, tankers, bulk carriers, RoRo ferries, and large motor yachts operating DEIF-based power management or generator control systems — as well as any vessel requiring a CAT III rated selectable AC transducer within its marine control system architecture.
Technical Support & Compliance
Technical assistance is available to support remote troubleshooting, onboard diagnostics, commissioning guidance, and integration queries related to this transducer and the wider DEIF control system it operates within. Retrofit and upgrade suitability, as well as compatibility with specific panels, controllers, or monitoring systems, is subject to confirmation based on the installation context. To confirm compatibility and ensure correct supply, buyers are encouraged to share nameplate photographs, the original part number (100087455.30), relevant wiring diagrams or system drawings, the control system model and software version, and where applicable, the vessel name and IMO number. All compatibility assessments are subject to confirmation upon review of the provided documentation.
