Product Introduction
The GE DS200TCRAG1ACC is a specialized printed circuit board engineered for the Speedtronic Mark V gas and steam turbine control ecosystem. Operating as a Relay Output Board (TCRA), it provides a robust switching and interface hub designed to manage heavy-duty discrete outputs, auxiliary control signals, and trip/alarm commands from the core control architecture to external plant actuators.
The board is densely populated with electro-mechanical plug-in relays (typically housing around 30 individual relays) alongside multiple 34-pin and 12-pin interface headers, ensuring clean signal translation, isolation, and high-reliability switching across demanding power-generation environments.

Compliance & Standards Alignment
- Designed and manufactured in strict compliance with heavy industrial electrical specifications for power generation, turbine management, and critical protection control loops.
- Treated with standard industrial PCB conformal coating to resist ambient moisture, airborne dust, and corrosive degradation inside industrial control cabinets.
Technical Note: When troubleshooting or replacing relays on the TCRA board, ensure that replacement plug-in relay modules match the exact coil voltage and contact rating specifications of the original factory assembly to prevent driver circuit overload.
Storage & Asset Preservation Guidelines
- Store the circuit board hermetically sealed inside its original metallized anti-static (ESD) shielding bag to safeguard sensitive solid-state relay drivers and logic components from electrostatic discharge.
- Maintain warehouse storage environments where relative humidity is strictly kept below 60% to prevent terminal pin and relay socket oxidation.
- Avoid mechanical stacking or heavy pressure on the board to prevent structural micro-fractures in the printed circuit substrate or physical damage to the plug-in relays.
Physical Installation Prerequisites
- Ensure that all system power feeds, auxiliary output loops, and cabinet interfaces are completely de-energized and locked out (LOTO) prior to handling, wiring, or card replacement.
- Mount the board securely into its designated slot or sub-panel within the Mark V control/termination cabinet using all specified fastening hardware to maintain panel ground continuity.
- Verify that all ribbon cable connectors and plug-in relays are firmly seated in their respective sockets prior to system re-energization.
Buyer’s FAQ & Logistics
Q: What Harmonized System (HS) code applies to this Mark V relay output board?
A: Industrial electronic control system printed circuit assemblies and control panel components typically classify under HS code 8538.90 (parts suitable for use solely or principally with control apparatus). Confirm final classification parameters with your licensed customs broker.
Q: What does the “ACC” suffix designate on this TCRA part number?
A: The suffix denotes the hardware grouping (G1), major revision tier (A), and specific artwork/component layout revisions (CC). Always cross-reference your system’s panel bill of materials (BOM) before substituting alternative board versions.
Q: Is the listed online price final for procurement?
A: Note: Price is subject to market conditions and available surplus inventory levels; contact our technical sales desk for a formal, time-sensitive quotation.
