GE DS200TCRAGIACC Relay Output Board(XIONGBA)

Product Overview

The GE DS200TCRAGIACC is a Relay Output Board engineered for GE’s Mark V Speedtronic turbine control system, serving as a critical component for signal conditioning and actuation in steam, gas, and wind turbine applications. Belonging to the legacy DS200 series, this module is designed to execute precise relay-based control commands, enabling safe and efficient operation of turbine systems in mission-critical industrial environments.

As part of the Mark V system’s Digital I/O Core (QD or C Core), the GE DS200TCRAGIACC interfaces with control processors to manage 30 plug-in relays, each rated for 0.5A, ensuring reliable actuation of solenoid valves, motor starters, and other field devices111. The board features 4×34-pin connectors (JOR, JOS, JOT, JO) and 4×12-pin connectors (JS3, JS4, JS5, JS6), providing flexibility for integrating with auxiliary control modules like the DTBC and DTBD expansion boards111. Its triple modular redundancy (TMR) architecture ensures continuous operation even if one channel fails, making it ideal for high-reliability applications in power plants and offshore platforms.

Key functions include relay logic control, signal isolation, and diagnostic feedback, supporting real-time monitoring of turbine health and safety parameters. The module’s robust design, with PCB coating for EMC protection and IP20-rated housing, ensures durability in harsh industrial conditions with temperatures ranging from -20°C to +60°C111.

Technical Specifications

Main Features and Advantages

High-Reliability Relay Control:
The GE DS200TCRAGIACC integrates 30 individually replaceable relays, each capable of handling 0.5A loads, ensuring precise actuation of critical turbine components like emergency trip valves and bypass systems. The TMR architecture ensures fault tolerance by cross-checking signals across three independent channels, minimizing downtime risks111.

Flexible Connectivity:
With 4×34-pin and 4×12-pin connectors, the board supports seamless integration with other Mark V modules, including the DS200TBQBG1ACB analog terminal board and DS200TCEAG1BSF emergency overspeed board. This scalability allows for customized control solutions in complex turbine setups16.

Industrial-Grade Durability:
Constructed with a PCB coating to resist dust, moisture, and electromagnetic interference, the module operates reliably in extreme conditions. Its 3U form factor and robust mounting design ensure stability in high-vibration environments typical of power generation and heavy industry111.

Simplified Maintenance:
Diagnostic LEDs and jumper configurations enable quick fault identification, while field-replaceable relays reduce repair time. The board’s compatibility with GE’s Control Builder software allows for firmware updates and configuration adjustments without system downtime1112.

Application Areas

Power Generation:
In coal-fired and combined-cycle power plants, the GE DS200TCRAGIACC controls steam turbine valves, bypass systems, and lubrication pumps. Its TMR architecture ensures uninterrupted operation during load fluctuations, while relay logic safeguards against overspeed or mechanical failures611.

Oil & Gas:
Offshore platforms and refineries use this module to manage compressor anti-surge valves, emergency shutdown systems, and hydraulic actuators. The board’s redundant design and high-temperature tolerance make it suitable for 24/7 operations in corrosive and high-pressure environments612.

Heavy Industry:
Steel mills and cement plants rely on the GE DS200TCRAGIACC to integrate with PLCs and robotic systems for conveyor belt control, furnace dampers, and material handling equipment. Its diagnostic capabilities enable predictive maintenance, optimizing production efficiency612.
