Product Introduction
The GE DS200TBCBG1AAA is a specialized termination circuit board designed for the Speedtronic Mark V gas and steam turbine control system architecture. Functioning as an RTD Input Termination Board (TBCB), it acts as the primary field wiring interface for resistance temperature detectors (RTDs) and select analog measurement loops.
The board securely terminates external field sensor cabling, filters incoming electrical noise, and routes temperature metrics cleanly to downstream analog I/O processor boards (such as the TCCB module) via heavy-duty internal ribbon cables and plug-in connectors, ensuring thermal measurement precision across critical turbine sections.

Compliance & Standards Alignment
- Designed and manufactured in strict compliance with rigorous industrial specifications for power generation, turbine automation, and heavy electrical environments.
- Factory-treated with standard PCB conformal coating to resist atmospheric moisture, salt mist, and chemical degradation inside terminal compartment enclosures.
Technical Note: When servicing or replacing termination boards, meticulously tag and map each incoming RTD field wire to prevent wiring offset errors that could distort temperature measurement calibration loops.
Storage & Asset Preservation Guidelines
- Store the termination circuit board hermetically sealed inside its original metallized anti-static (ESD) shielding bag to protect mounted components and connector pins from static discharge and oxidation.
- Maintain warehouse storage environments where relative humidity is strictly kept below 60%.
- Avoid mechanical stacking or heavy pressure on the board to prevent physical damage to terminal block housings or structural board flexing.
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 core termination cabinet using all specified mounting fasteners to maintain panel ground bonding.
- Verify that terminal screws are properly torqued down on field conductors to prevent high-resistance connections or intermittent signal drops under heavy industrial vibration.
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: Is the DS200TBCBG1AAA compatible with thermocouple inputs?
A: No, the TBCB series is engineered specifically for RTD (Resistance Temperature Detector) and matching low-level analog configurations. Thermocouples require dedicated cold-junction compensation termination boards (such as the TCCV or TCAI series).
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.
