GE DS200TCQBG1BCB / DS215TCQBG1BZZ01A – Extended Analog I/O Board | GE Mark V DCS Platform
Engineering Background
The DS200TCQBG1BCB (board assembly) and DS215TCQBG1BZZ01A (module assembly) are GE’s Extended Analog I/O Boards designed for the Mark V Turbine Control System — GE’s flagship DCS platform widely deployed in gas turbine, steam turbine, and combined-cycle power generation facilities worldwide. These boards extend the analog signal processing capacity of the Mark V I/O rack, enabling high-density sensor interfacing for critical process control loops.
Product Positioning
Targeted at maintenance engineers and procurement specialists managing aging Mark V fleets, this board provides a direct OEM-equivalent replacement path. Konmask.com stocks both new-surplus and professionally refurbished units, each verified against GE’s original functional specifications before shipment.

System Architecture & Signal Flow
Within the Mark V architecture, the TCQB board resides in the I/O expansion rack and communicates with the TCCA (Controller Card) via the Mark V backplane bus. Analog field signals (thermocouples, RTDs, pressure transmitters, flow transmitters) are wired to the terminal board, conditioned by the TCQB’s signal conditioning circuitry, and digitized for the TCCA’s control algorithms. The DS215 module assembly integrates the DS200 board with the terminal interface, simplifying field wiring and reducing installation time.
Typical signal chain: Field sensor → Terminal Board → DS200TCQBG1BCB signal conditioning → Mark V backplane → TCCA controller → Control output

Technical FAQ
Q: Is DS200TCQBG1BCB the same as DS215TCQBG1BZZ01A?
A: DS200TCQBG1BCB is the bare PCB board assembly; DS215TCQBG1BZZ01A is the complete module assembly including the board and terminal interface. In most Mark V replacement scenarios, either can fulfill the requirement — confirm with your panel drawing before ordering.
Q: Which Mark V configurations use this board?
A: This board is used in Mark V systems with extended analog I/O requirements, commonly found in GE Frame 6B, 7E, 7F, and 9E turbine control panels. Verify against your Mark V I/O rack drawing (GE document series 369A).
Q: Can this board be used in a Mark VI or Mark VIe system?
A: No. The Mark VI and Mark VIe use a different I/O architecture (IONET/ENET based). This board is specific to the Mark V backplane bus.
Q: What is the lead time for emergency orders?
A: In-stock units can be dispatched same day (order before 14:00 CST). Express DHL/FedEx delivery to most countries within 3–5 business days.
Q: Do you provide a warranty?
A: Yes. All units carry a 12-month functional warranty. DOA units are replaced or refunded within 30 days of receipt.
