GE DS200DTBAG1AAA – Digital Input Terminal Board | Mark V/VI DCS Platform
Engineering Background
The DS200DTBAG1AAA is a Digital Input Terminal Board designed and manufactured by General Electric as part of the Mark V and Mark VI Distributed Control System (DCS) platform — one of the most widely deployed turbine control architectures in power generation, oil & gas, and heavy industrial facilities worldwide. This board serves as the primary field-wiring interface for discrete digital input signals, bridging field instrumentation with the core control processor modules.
Product Positioning
Engineered for mission-critical environments where signal integrity and system uptime are non-negotiable, the DS200DTBAG1AAA is the preferred replacement and spare-parts solution for plant engineers managing aging Mark V/VI control systems. Konmask.com supplies this board from verified surplus and refurbished channels, providing a cost-effective alternative to OEM new pricing without compromising on reliability.

System Architecture & Signal Flow
In the Mark V/VI DCS architecture, the DS200DTBAG1AAA mounts in the I/O terminal board slot of the control panel enclosure. Field instrument cables (limit switches, proximity sensors, relay contacts, etc.) terminate directly at the board’s screw terminals. The terminal board routes conditioned digital input signals via the backplane ribbon or direct connector to the corresponding I/O processor module (e.g., DSPX, DSPC). The processor module then communicates signal states to the core TCCA/TCCB control processors over the internal VME or proprietary GE bus. This architecture ensures deterministic scan times and high noise immunity critical for turbine protection logic.

Technical FAQ
Q: Is DS200DTBAG1AAA compatible with both Mark V and Mark VI systems?
A: The board is primarily designed for the Mark V platform. Mark VI compatibility depends on the specific I/O backplane revision in your panel. Please confirm your panel’s backplane part number before ordering.
Q: Do you provide a test report with the board?
A: Yes. A basic functional test record is available upon request. For critical applications, we recommend final validation in your own test rig or during a planned maintenance window.
Q: What is the lead time if the board is not in stock?
A: Typical lead time for sourcing from our supplier network is 5–15 business days. We will confirm availability and lead time at the quotation stage.
Q: Can you supply multiple units for a spare-parts program?
A: Yes. We support bulk procurement for plant spare-parts programs. Contact us for volume pricing.
Q: What shipping methods are available for international orders?
A: We ship via DHL Express, FedEx International, and UPS Worldwide. Customs documentation (commercial invoice, packing list, HS code declaration) is provided with every international shipment.
