Description
The GE IS200TBAIH1CED is an analog input terminal board manufactured for the Mark VI Speedtronic gas and steam turbine control system. It provides physical termination points for up to 24 analog inputs, accepting a mix of two-wire, three-wire, and four-wire transmitters, including 4 to 20 mA loop-powered devices and ±10 V DC voltage inputs. The board routes these signals through two high-density connectors directly to the internal VAIX or PAIC analog input processor cards.
We hold this item in stock as a New Original (New Surplus) unit, arriving in its factory-sealed protective packaging. Because the Mark VI legacy infrastructure experiences highly critical, volatile demand patterns for power generation maintenance, our listed price serves as a general market reference only. Price is subject to market conditions; contact us for a firm quote to establish final pricing and delivery timelines. Every unit includes our 12-month replacement warranty, which takes effect on the day the shipment passes your facility’s incoming technical inspection.
Field Deployment and Integration Constraints
On a recent turbine control panel modernization project, we integrated this specific “CED” revision board to replace an older “1AAA” variant that had suffered trace damage from a field grounding fault. When mounting this board to the DIN rail rack, you must account for its specific terminal density. The board features three terminal blocks, each containing 24 barrier screw points, totaling 72 terminal nodes.
A common field error occurs when wiring passive 4 to 20 mA loop-powered transmitters. While the board distributes a nominal 24 V DC excitation voltage across designated terminals, it does not possess independent channel-to-channel optical isolation. Well, technically the inputs share a common return bus, meaning that a severe short-to-ground on a single field sensor can destabilize adjacent loops sharing that specific input group. In field deployments, we found that isolating high-risk outdoor instrumentation using external signal conditioners before hitting the IS200TBAIH1CED prevents wide-scale channel dropouts during lightning surges.

Before modifying your system’s hardware configuration, check your specific slot layout requirements using the official Mark VI Turbine Control System Guide (GE Document GEH-6421). One colloquial judgment to pass along: don’t underestimate the diagnostic jumpers on this board. The small plug-in jumpers configure individual channels between current and voltage modes; if you leave a jumper set to voltage while applying a current loop, your input reading will flatline at the upper rail limit, throwing a system diagnostic alarm on your HMI.
Global Logistics and Cross-Border Compliance
Shipping high-reliability power generation control elements like the IS200TBAIH1CED requires adherence to global trade regulations. Because this board interfaces with turbine control systems running in critical energy infrastructure, it undergoes thorough export control reviews prior to shipment. Our dedicated logistics team handles precise Harmonized System (HS) code assignment and monitors international compliance lists to prevent customs clearance delays.
Cross-Border Logistics and Carrier Selections
We execute international orders under EXW (Ex Works) or FCA (Free Carrier) terms from our regional stocking warehouses, giving your freight forwarding agents full custody of transit routes and customs processing. If your procurement process requires an end-to-end transport solution, we can quote DAP (Delivered at Place) terms, executing the international air freight, managing export filings, and scheduling direct delivery to your plant gates.
- Priority Courier Infrastructure: DHL Express, FedEx International Priority, or UPS Worldwide Express. Worldwide transit times average 2 to 5 business days, making this the standard option for minimizing forced outages.
- Standard Air Freight: Best for scheduled outages, turbine overhauls, or multi-panel rebuilds where this terminal board travels alongside bulk structural components, matching power supplies, and logic cores.
To prevent customs holds at international borders, every shipment includes a standardized documentation package: a detailed commercial invoice stating true transaction values, an itemized packing list, an unexpired Certificate of Origin, and complete export declaration files. When importing into major industrial centers across North America, Europe, or the Middle East, border agents often verify the physical manufacturer part number stamp against your manifest papers. Our strict documentation control ensures every letter and digit matches perfectly to prevent paperwork-related delays.
Procurement Frequently Asked Questions
What does the “CED” suffix indicate regarding board revision compatibility? The “CED” suffix denotes the specific artwork revision and component bill of materials applied during production. In Mark VI control networks, a newer revision board can typically replace an older revision (such as “CEA”) in simplex setups, but you must verify with your OEM system documentation if you are running a Triple Modular Redundant (TMR) architecture, as mismatched board revisions across tracking legs can lead to voting errors.
What payment options are available for international utility and B2B buyers? To accommodate corporate accounting standards and comply with international banking regulations, we process transactions via upfront telegraphic wire transfer (T/T). For extensive utility modernization projects or large-scale municipal contract values crossing $50,000 USD, we can process orders via an irrevocable Letter of Credit (L/C) payable at sight.
Are the input fuses field-replaceable, and are they included? Yes. The board houses built-in, surface-mounted fuses designed to protect the 24 V DC excitation circuits from field wiring shorts. These fuses come fully installed on our New Original boards. If a field short occurs, the fuse will blow to isolate that specific channel group; you can inspect and swap them out using standard electronics tools without having to replace the entire board assembly.
