RANGE: 0-1 A
INPUT: 0-1 A
OUTPUT: 0-20MA
LOAD: <750 Ω
SUPPLY: NONE
The DEIF TAC-120DG is a precision current transducer designed to convert a 0–1A AC current input signal into a corresponding 0–20mA analogue output signal. Operating without an external supply, this self-powered transducer draws its energy directly from the measured current, simplifying installation and reducing wiring complexity. It forms a critical part of marine control and monitoring systems where accurate current measurement is essential for generator management, power distribution, and load-monitoring applications. Within the broader Marine Control System category, transducers such as this serve as the interface between primary electrical circuits and control panels or automation systems, enabling accurate real-time feedback for safe vessel operation.
Key Features
✓ Converts 0–1A AC input to a 0–20mA analogue output signal, suitable for interfacing with standard marine control and monitoring equipment.
✓ Self-powered design (supply: none) — draws operating energy from the measured input circuit, eliminating the need for a separate auxiliary supply and reducing installation complexity.
✓ Maximum load resistance of less than 750 Ω on the output circuit, ensuring compatibility with typical analogue input cards and controller terminals — subject to confirmation for specific system configurations.
✓ Designed for integration within DEIF power management and generator control architectures, and may be compatible with third-party marine automation panels where 0–20mA analogue input is accepted — compatibility subject to confirmation.
✓ Compact transducer format suitable for mounting within control panels, switchboard enclosures, or automation cabinets in engine room and machinery spaces.
Marine Applications
✓ Generator control and power management panels aboard commercial vessels, where precise current monitoring is required for load sharing and alarm functions.
✓ Main switchboard and distribution board current monitoring systems on cargo ships, tankers, and offshore support vessels.
✓ Engine room automation and control systems requiring analogue signal conditioning from current transformers or shunt outputs.
✓ Retrofit and upgrade projects replacing faulty or obsolete transducers within existing DEIF-based or compatible control system installations.
✓ Auxiliary machinery monitoring systems on ferries, dredgers, and naval auxiliaries where reliable current signal conversion supports operational safety and efficiency.
Why Marine Engineers Choose
The DEIF TAC-120DG is valued for its self-powered, passive operation, straightforward analogue output, and reliable performance in the demanding electrical environments found aboard commercial and offshore vessels — making it a dependable replacement or spare component within marine power and control systems.
Ideal For
Cargo vessels, tankers, offshore support vessels, ferries, dredgers, and any commercial or industrial marine application operating DEIF or compatible power management and generator control systems requiring accurate current-to-analogue signal conversion.
Technical Support & Compliance
Technical assistance is available for remote troubleshooting, onboard support coordination, testing and commissioning guidance, and integration into existing or upgraded marine control systems. Retrofit and replacement suitability is subject to confirmation based on the specific installation. To confirm compatibility, buyers are encouraged to share nameplate photographs, existing part numbers or drawing references, the control system model and software version where known, and vessel name or IMO number along with the scope of the intended application. All compatibility and suitability assessments are subject to confirmation upon review of the provided technical information.
