GE DS200TCQBG1BCB RST Extended Trip and Control Board(XIONGBA)

Product Overview

The GE DS200TCQBG1BCB is a RST Extended Trip and Control Board designed for GE’s Mark V Speedtronic turbine control system, specializing in critical protection logic and signal conditioning for high-reliability industrial applications. Unlike earlier analog I/O modules in the DS200 series, this variant focuses on emergency trip circuit management and triple modular redundancy (TMR) synchronization, making it a core component in turbine overspeed protection, emergency shutdown sequences, and governor control systems .

The 1BCB suffix denotes a hardware revision optimized for EMC immunity and thermal stability in harsh environments. It features 24 configurable jumpers for field-adjustable signal scaling and 3×40-pin, 3×34-pin, and 1×16-pin connectors for versatile signal routing. The module’s TMR architecture ensures continuous operation even during single-channel failures, critical for applications where signal loss could lead to catastrophic system shutdowns .

Technical Specifications

Main Features and Advantages

Safety-Critical Trip Logic:
The DS200TCQBG1BCB integrates emergency trip relay control and overspeed protection algorithms, cross-checking signals from three independent channels to trigger turbine shutdowns within milliseconds of detecting anomalies. Its 24 jumpers allow dynamic adjustment of trip thresholds (e.g., speed, vibration) to align with specific turbine specifications .

TMR Redundancy for Mission-Critical Operations:
The triple modular redundancy architecture ensures fault tolerance by voting on signals across three parallel channels. This is vital for applications like offshore platforms, where equipment failure could lead to environmental disasters or production losses. The module also supports TMR cross-trip testing, enabling maintenance teams to verify redundancy without disrupting operations .

Industrial-Grade Durability:
With 1BCB hardware revisions, the module incorporates improved EMC shielding (meets EN 61000-6-2:2019) and corrosion-resistant PCB coatings, making it suitable for high-vibration, high-humidity environments. It withstands extreme temperatures and electrical noise in steel mills, chemical plants, and power generation facilities .

Flexible Configuration and Diagnostics:
Compatible with GE’s Control Builder software, the DS200TCQBG1BCB allows on-the-fly parameter adjustments (e.g., trip delay, relay response time) and supports hot-swapping for maintenance without system shutdown. Built-in diagnostic LEDs and self-tests simplify troubleshooting, reducing downtime .

Application Areas

Power Generation:
In coal-fired and combined-cycle plants, the DS200TCQBG1BCB monitors steam turbine speeds and positions for grid synchronization, triggering emergency shutdowns if overspeed or vibration thresholds are exceeded. Its TMR architecture ensures uninterrupted operation during transient grid disturbances .

Oil & Gas Operations:
Offshore platforms and refineries use this module for compressor anti-surge control and emergency shutdown systems. Its ability to handle high-voltage trip signals (up to 200V DC) makes it suitable for direct integration with solenoid valves and hydraulic actuators in high-pressure environments .

Heavy Industrial Automation:
Steel mills and cement plants integrate the DS200TCQBG1BCB with robotic arms and conveyor systems, providing fail-safe position feedback and overload protection. Its rugged design withstands constant vibration from heavy machinery, ensuring consistent process control .

Installation and Maintenance

Installation Preparation:
Mount the DS200TCQBG1BCB in a grounded VME rack within the Mark V system. Connect shielded high-voltage cables to the 40-pin connectors for trip signals and 34-pin connectors for power/synchronization. Use GE Control Builder software to configure jumper settings (e.g., trip thresholds, relay logic) and enable TMR redundancy. Verify proper ventilation to maintain optimal operating temperature .

Maintenance Recommendations:

• Quarterly Inspections: Check connectors for corrosion and cable integrity, especially in high-vibration environments.
• Annual Diagnostics: Run built-in TMR cross-trip tests via Control Builder to verify redundancy and signal accuracy. Replace backup batteries to preserve configuration data.
• Firmware Updates: Periodically update firmware to incorporate bug fixes and compatibility improvements for seamless integration with system upgrades .
