Product Introduction
The GE DS200TBCAG1AAB is a high-density printed circuit board designed for the Speedtronic Mark V gas and steam turbine control system architecture. Functioning as an Analog I/O Terminal Board (TBCA), it serves as the primary field wiring termination hub for low-level analog inputs, including resistance temperature detectors (RTDs), thermocouples, and standard 4–20 mA instrumentation loops.
The board securely bridges rugged field cabling with internal rack-mounted processor and conditioning cards via multi-pin ribbon connectors, maintaining precision signal fidelity and noise rejection in demanding power-generation environments.

Compliance & Standards Alignment
- Designed and manufactured in strict compliance with heavy industrial electrical specifications for power generation and large rotating equipment management.
- Factory-treated with standard industrial conformal coating to resist humidity, airborne dust, and corrosive elements inside turbine terminal cabinets.
Technical Note: When mapping or replacing field wires on the TBCA board, verify thermocouple cold-junction placement or RTD three-wire lead configurations precisely against plant wiring drawings to prevent measurement calibration errors.
Storage & Asset Preservation Guidelines
- Store the circuit board hermetically sealed inside its original metallized anti-static (ESD) shielding bag to protect mounted components and multi-pin headers from static discharge.
- Maintain warehouse storage environments where relative humidity is strictly kept below 60% to prevent terminal block corrosion.
- Avoid mechanical stacking or heavy pressure on the board to prevent physical damage to terminal block housings or board flexure.
Physical Installation Prerequisites
- Ensure that all field sensor loops, power feeds, and cabinet interfaces are completely de-energized and locked out (LOTO) prior to handling, wiring, or replacement.
- Mount the board securely onto the designated sub-panel within the Mark V termination cabinet using all specified mounting hardware to maintain structural ground bonding.
- Verify that terminal screws are properly torqued down on incoming multi-core conductors to prevent high-resistance connections or vibration-induced loosening.
Buyer’s FAQ & Logistics
Q: What Harmonized System (HS) code applies to this Mark V termination board?
A: Industrial electronic control system printed circuit assemblies and control panel parts 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: Can the DS200TBCAG1AAB handle both RTDs and thermocouples?
A: Yes, the TBCA board is designed to route mixed low-level analog inputs including RTDs and thermocouples depending on core configuration and downstream conditioning board mapping.
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.
