DS200DCFBG2BNC MRP445970 GE core DC feedback board

Description

DS200DCFBG2BNC (MRP445970) – Brief Introduction & Technical Specifications
Brief Introduction
DS200DCFBG2BNC with material reference number MRP445970 is a core DC feedback board developed by GE Power Systems, belonging to the GE Mark V series of control system modules. It is specifically engineered for signal processing and feedback transmission in the Mark V distributed control system (DCS) and programmable logic controller (PLC) applied in power generation and industrial rotating equipment control. The module is designed to collect and condition DC analog feedback signals from field sensors and actuators, convert them into standard signals recognizable by the Mark V main controller, and realize stable data interaction between the field device layer and the upper control layer. It is a key supporting component for the safe and reliable operation of GE Mark V control systems in gas turbine, steam turbine and other heavy industrial equipment control scenarios.

Technical Specifications
Basic Information
The brand of the module is GE; the primary model is DS200DCFBG2BNC, and its exclusive material reference number is MRP445970, which is the standard coding for procurement and inventory management of this product.
Weight & Dimensions
The net weight of the DS200DCFBG2BNC module is approximately 0.45 kilograms (1.0 pound), with a compact structural design suitable for cabinet-mounted installation in industrial control enclosures. The physical dimensions of the module are about 152 millimeters in length, 102 millimeters in width and 25 millimeters in thickness (6.0 inches × 4.0 inches × 1.0 inches), matching the installation hole position and space layout of the GE Mark V system cabinet, without additional installation adaptation.
Inputs
This DC feedback board is equipped with multi-channel industrial-grade DC analog input ports, which support the collection of standard DC voltage and current feedback signals from field devices. The main input signal ranges include 0-5V DC, 0-10V DC voltage signals and 4-20mA DC current signals, and the input ports have anti-surge and anti-interference protection circuits, which can stably collect weak feedback signals in the industrial harsh environment with high electromagnetic interference. All input channels have independent signal conditioning circuits to ensure the accuracy of signal collection and avoid cross-channel interference.
Outputs
The module outputs the conditioned and converted digital feedback signals to the GE Mark V main controller through the dedicated backplane communication bus of the Mark V system, with the output signal complying with the internal communication protocol of the GE Mark V control system to realize real-time and high-speed data transmission. In addition, it is equipped with auxiliary status output signals, which can output the running state and fault alarm digital signals of the module itself to the system’s fault diagnosis unit, with the output type being dry contact digital signals for easy connection with the system’s alarm and indicator devices.
Key Features
The module adopts industrial-grade high-temperature resistant electronic components, with a wide operating temperature range, and can work stably in the industrial environment of -40°C to +85°C, meeting the temperature requirement of heavy industrial equipment control sites;
It has excellent electromagnetic compatibility (EMC), with built-in ESD and surge protection circuits, which can resist the electromagnetic interference of high-voltage and high-current equipment on the site, ensuring the accuracy of signal transmission;
It is fully compatible with the GE Mark V control system, realizing plug-and-play with the system backplane and cabinet, and the modular design makes the disassembly, replacement and maintenance simple and fast, reducing the system downtime;
It has independent self-detection and fault diagnosis functions, which can real-time monitor the working state of the module’s input channels, circuits and communication links, and send fault signals in time when an abnormality occurs, improving the maintainability of the system;
The signal collection and conversion have high precision, the analog-to-digital conversion accuracy reaches 16-bit, and the signal transmission delay is less than 10ms, meeting the real-time control requirement of gas turbine and steam turbine equipment;
It has a compact and rugged mechanical structure, with a metal shell for dustproof and shockproof protection, adapting to the vibration and dust environment of industrial equipment operation sites.
