The DEIF TDG-210DG/2 is a DC insulation amplifier designed to provide galvanic isolation between signal circuits in marine automation and control systems. Operating on a 24 VDC supply, it accepts a standard 4–20 mA input signal and delivers an isolated –1 to +1 mA output, making it a critical interface component in shipboard monitoring, power management, and generator control installations. As part of the Marine Control System category, it ensures signal integrity and electrical safety across interconnected onboard networks, protecting sensitive instrumentation from ground loops and transient interference that are common in the marine environment.
Key Features
✓ Provides galvanic DC isolation with a 4–20 mA input and a –1 to +1 mA isolated output, supporting clean signal transmission between control circuit segments.
✓ Operates from a 24 VDC supply with a power consumption of 2.5 W; load impedance range spans from 50 Ω to less than 15,000 Ω, as specified in the original product data.
✓ Compatible with DEIF marine control and generator management systems where isolated analogue signal conditioning is required between sensors, transmitters, and control panels.
✓ Suited for installation in control panels, switchboard enclosures, and automation cabinets in dry machinery spaces; exact mounting configuration and enclosure requirements are subject to confirmation based on installation drawings.
✓ Serves as a direct replacement or service part within existing DEIF-based control architectures, minimising downtime during scheduled maintenance or fault rectification — compatibility with specific system versions should be verified against nameplate data.
Marine Applications
✓ Generator control and power management panels on merchant vessels, offshore platforms, and naval auxiliaries where isolated 4–20 mA signal loops are required.
✓ Engine room automation systems integrating sensors and transmitters that require electrical isolation from the main control network.
✓ Propulsion monitoring and alarm systems where signal amplifiers prevent interference between high-voltage and low-voltage circuit domains.
✓ Dynamic positioning (DP) vessel control infrastructure and integrated automation systems requiring precise, interference-free analogue signal conditioning.
✓ Retrofit and upgrade projects on existing DEIF-equipped vessels where ageing insulation amplifiers require like-for-like replacement to maintain system performance.
Why Marine Engineers Choose
Marine engineers specify the DEIF TDG-210DG/2 for its defined electrical characteristics, direct compatibility with DEIF control system architectures, and its role in maintaining signal fidelity and crew safety by isolating analogue circuits in demanding shipboard environments.
Ideal For
Merchant cargo vessels, tankers, offshore supply vessels, platform supply vessels (PSVs), ferries, cruise ships, and any commercial or industrial marine vessel operating DEIF-based power management or automation control systems.
Technical Support & Compliance
Remote and onboard technical support is available to assist with troubleshooting, testing, commissioning, and integration of this insulation amplifier into existing control systems. Repair, retrofit, and upgrade services can be discussed depending on system configuration — all compatibility assessments are subject to confirmation. To confirm suitability for your application, buyers are encouraged to share nameplate photographs, the full part number and variant reference, relevant wiring or loop diagrams, the specific DEIF system model and software version, and where applicable, the vessel name and IMO number along with the scope of the intended installation or replacement.
