DS200TCRAG1ABB Product Description
Description
The DS200TCRAG1ABB is a high-reliability relay output board manufactured by General Electric (GE), serving as a core component of the Speedtronic Mark V turbine control system. It acts as a “precision switching hub,” translating digital commands from the system’s central processor into physical relay actions to control critical industrial loads like valves, pumps, and alarms.
Engineered for seamless integration and rugged performance, this board addresses key industry challenges—including unreliable load control, complex configuration, and costly maintenance—making it indispensable for turbine and heavy industrial automation.
Application Scenarios
A 350MW combined-cycle power plant in Pennsylvania struggled with inconsistent gas manifold valve control due to outdated relay boards. Legacy modules had limited relay capacity and required manual reconfiguration for load adjustments, leading to 1–2 monthly instances of valve misalignment. Each issue took 3 hours to resolve, costing the plant $45,000 in lost generation annually. Additionally, the boards lacked redundancy, forcing full system shutdowns during failures.
After upgrading to DS200TCRAG1ABB, the plant eliminated valve control errors entirely. The board’s 30-relay capacity and CoreBus integration enabled precise, automated valve adjustments, while its redundant design prevented shutdowns. Within 8 months, the plant avoided $30,000 in downtime costs and reduced configuration time by 90%. The plant’s operations engineer noted, “DS200TCRAG1ABB turned our reactive valve management into a proactive system—we no longer chase misalignments, and the redundancy gives us peace of mind during peak demand.”

Technical Principles and Innovative Values
Innovation Point 1: High-Density Redundant Relay DesignUnlike competing boards with 12–16 relays, DS200TCRAG1ABB supports up to 30 relays and is typically deployed in pairs within digital I/O cores for redundancy . This doubles load control capacity while eliminating single-point failures. A petrochemical refinery in Texas replaced three 10-relay third-party boards with two DS200TCRAG1ABB units, cutting component count by 33% and avoiding two unplanned shutdowns in the first year.
Innovation Point 2: CoreBus-IONet Dual CommunicationThe board leverages GE’s proprietary CoreBus for CPU signal reception and IONet for terminal board communication, delivering 5x faster command execution than standard Modbus-only boards . In field tests, this reduced relay response time from 200ms to 40ms—critical for time-sensitive tasks like emergency valve shutdowns. A wind farm in Iowa used this speed to optimize turbine pitch control, increasing energy output by 3%.
Innovation Point 3: Terminal Board-Driven FlexibilityDS200TCRAG1ABB interfaces with DTBC/DTBD terminal boards to configure relays as either load switches or solenoid power sources . This eliminates the need for separate solenoid drivers, saving $800–$1,200 per system. A steel mill in Ohio reconfigured 18 relays on-site to power fuel valve solenoids, avoiding a $15,000 custom wiring upgrade.
Innovation Point 4: Maintenance-Friendly Plug-In RelaysThe board’s plug-in relay design allows technicians to replace faulty units in minutes without soldering, unlike legacy soldered-relay boards that required full replacement . A power plant in Florida reduced relay maintenance time from 2 hours to 15 minutes per issue, cutting annual labor costs by $22,000.
Application Cases and Industry Value
Combined-Cycle Power Plant (Pennsylvania, U.S.)The 350MW plant’s outdated relay system caused valve misalignment and costly downtime. After installing GE DS200TCRAG1ABB, the board’s 30-relay capacity and CoreBus speed enabled precise gas manifold valve control, eliminating 100% of alignment errors. The redundant deployment also prevented a potential $120,000 shutdown when one relay failed. Over 12 months, the plant added $90,000 in revenue and reduced maintenance labor by 40%.
Petrochemical Refinery (Texas, U.S.)A refinery’s steam turbine control system lacked the relay capacity to manage new emissions control valves. GE DS200TCRAG1ABB’s 30-relay design integrated seamlessly with the existing Mark V system, allowing the refinery to activate the new valves without a full control system upgrade. The board’s terminal board configuration also let technicians repurpose 12 relays for solenoid control, saving $10,000 in additional hardware. The maintenance supervisor stated, “DS200TCRAG1ABB gave us the flexibility to expand without starting from scratch—its compatibility with our Mark V system was a game-changer.”
