Product Introduction
The GE DS200TCCBG1BED is a critical printed circuit board utilized within the Speedtronic Mark V gas and steam turbine control system. Functioning as a Common Extended Analog I/O Board (TCCB), it provides signal scaling, conditioning, and routing capabilities for a wide variety of analog process inputs.
The board coordinates closely with core terminal boards (such as the TBCB and TCEB modules) to process critical telemetry data—including 4–20 mA / 0–1 mA control loops, RTD temperature metrics, generator/bus voltages, and line currents—before passing the conditioned data via the 3PL bus connector to the main control processors.

Compliance & Standards Alignment
- Designed and manufactured in strict compliance with heavy industrial electrical specifications for power generation and large-scale rotating equipment control.
- Includes factory-applied PCB conformal coating to resist humidity, airborne particulates, and chemical degradation inside harsh turbine enclosure environments.
Technical Note: Configuration of hardware scaling parameters relies on onboard jumpers (such as J1–J5 for voltage/current monitoring loops) alongside software configuration constants entered via the Mark V HMI I/O Configuration Editor.
Storage & Asset Preservation Guidelines
- Store the circuit board hermetically sealed inside its original metallized anti-static (ESD) shielding bag to protect sensitive CMOS integrated circuits from electrostatic discharge.
- Maintain warehouse storage environments where relative humidity is strictly kept below 60% to prevent edge-connector oxidation.
- Avoid mechanical stacking or heavy pressure on the board to prevent structural micro-fractures in the multi-layer printed circuit substrate.
Physical Installation Prerequisites
- Ensure that all rack power supplies and associated turbine control cabinet power feeds are completely de-energized and locked out (LOTO) prior to board handling or replacement.
- Slide the board carefully into its designated card guides within the Mark V control core, confirming clean and complete engagement with backplane pin headers.
- Verify that all plug-in ribbon connectors (such as 2PL and 3PL) are firmly seated and locked to prevent intermittent signal dropouts during machinery operation.
Buyer’s FAQ & Logistics
Q: What Harmonized System (HS) code applies to this Mark V analog I/O board?
A: Industrial electronic control system printed circuit assemblies and processor components typically classify under HS code 8538.90 (parts suitable for use solely or principally with control apparatus). Confirm final categorization parameters with your licensed customs broker.
Q: Does the “BED” suffix indicate a specific hardware revision?
A: Yes, suffix identifiers like “G1BED” denote specific layout, firmware, or component revision iterations relative to the base TCCB design blueprint. Check compatibility with your existing Mark V panel documentation before installation.
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.
