DEIF Delomatic Modular Generator Set Integrated System

System Overview

Product Positioning

DEIF Delomitic-3 is a highly customized, distributed and multifunctional power station control and protection system designed specifically for ship power stations, public power plants, and cogeneration CHP units. It integrates control, relay protection, measurement, synchronization, and remote communication, and supports collaborative management of multiple units.

Core components of the system

DGU: Generator Control Unit (Rack mounted Modular Plug in Box, 1 set of DGU per generator set)

CP control panel: human-machine operation slave station, with a maximum of 3 CP panels externally connected to a single DGU

ARC-NET Token Ring Bus: a dedicated LAN within the system that connects all DGUs to the operation panel

CM-2 Communication Conversion Module: External docking with upper level SCADA and monitoring systems, outputting universal serial port protocols such as Modbus RTU

Core Features

Modular free selection, add or remove input/output/protection/synchronization boards as needed;

The control panel is a slave device, and panel damage does not affect the internal control and protection logic of DGU;

A single ARC bus can connect up to 8 sets of DGUs and 24 operation panels;

Complete factory documentation, factory FAT testing, and full lifecycle technical support;

Support multi-layer human-computer interaction with graphical interface, local panel, and upper software.

CP operation control panel (human-machine slave station)

Each DGU can be equipped with up to 3 CP panels, which communicate with the host through the ARC bus and have the following functions:

LCD display screen: real-time measurement value viewing, parameter tuning, and full alarm information display;

16 channel status LED indicator lights, used for quick indication of running/fault status;

Up to 16 pointer instruments can be connected externally;

No independent control logic, all programs and settings are stored in the DGU host, and panel faults do not trip or lose protection.

DGU Generator Unit: Rack and Hardware Modules

1. DGU rack standard

The rack complies with the German railway standard BN411002/BN411003, and the backplane integrates a unified flat system bus. It is equipped with various modules in a rail mounted manner and offers two specifications:

Rack specifications available slot TE size (width x depth x height mm) bare weight

84TE 84 426.7×465.1×483.0 3.5kg

60TE 60 304.8×343.2×361.1 3.0kg

Installation method: either base surface installation or cabinet embedded installation; Unused slot with dust cover to maintain IP20 protection.

Optional shock absorption kits are available for ship operating conditions, with weight increases of 1.2kg (84TE)/0.9kg (60TE) respectively. Shock absorption kits are standard for ship frames.

Environmental protection: IP20 for the front and rear of the whole machine; The flame retardant grade of plastic parts is UL94-V0.
