The DEIF TDG-210DG/2 is a dedicated insulation amplifier designed to provide galvanic isolation between signal circuits in marine control and monitoring systems. Operating on a 24V DC supply, it accepts and outputs a 4–12–20 mA analogue signal, making it directly compatible with standard two-wire and three-wire instrumentation loops found throughout vessel automation architectures. This component plays a critical role in protecting sensitive control equipment from ground loops, electrical noise, and potential differences that are common in the shipboard environment — particularly in engine rooms, machinery control rooms, and integrated automation panels. As part of a Marine Control System, the TDG-210DG/2 ensures signal integrity across isolated boundaries, contributing to reliable data transmission between sensors, controllers, and display units.
Key Features
✓ Galvanic signal isolation with matched 4–12–20 mA input and output, maintaining loop accuracy across isolated circuit boundaries.
✓ Operates on a 24V DC supply voltage, consistent with standard DIN-rail power distribution used in marine automation and control panels.
✓ DEIF part reference 405240.10 — compatible with DEIF generator control and power management architectures, subject to system version confirmation.
✓ Compact amplifier format suited to panel-mount or DIN-rail installation in dry, climate-controlled spaces such as machinery control rooms or switchboard enclosures.
✓ Designed as a drop-in replacement or service spare within existing DEIF-based control loops; compatibility with specific panel configurations should be confirmed against nameplate data and system drawings.
Marine Applications
✓ Generator control and power management systems aboard merchant vessels, offshore platforms, and naval auxiliaries using DEIF controllers.
✓ Engine room automation loops where analogue signal isolation is required between sensors and remote I/O or monitoring units.
✓ Integrated bridge and machinery alarm monitoring systems requiring clean, noise-free 4–20 mA signal transmission.
✓ Retrofit and upgrade projects on older tonnage where signal interference or ground loop issues affect instrumentation reliability.
✓ Newbuild and commissioning installations where analogue isolation amplifiers are specified as part of the control system architecture.
Why Marine Engineers Choose
The DEIF TDG-210DG/2 is a trusted component within DEIF’s established ecosystem, offering a straightforward, proven means of isolating analogue signals without introducing latency or signal degradation — critical where accurate monitoring underpins safe vessel operation.
Ideal For
Merchant vessels, offshore support vessels, ferries, tankers, bulk carriers, and any platform operating DEIF-based power management or generator control systems requiring analogue signal isolation.
Technical Support & Compliance
Remote troubleshooting, onboard commissioning guidance, integration support, and retrofit assistance are available, subject to confirmation. To verify compatibility with your installation, please provide nameplate photographs, the DEIF system model and software version, relevant wiring diagrams or loop drawings, panel part numbers, and vessel name or IMO number where applicable. All compatibility and suitability assessments are subject to confirmation upon review of the above documentation.
