Current secondary inventory records identify IS200TPROS1CBB as a GE Mark VI TPROS terminal board and report approximately 180 × 180 × 30 mm and 0.8 kg. These logistics figures should be treated as estimates rather than OEM-certified dimensions.

Product Introduction

The GE IS200TPROS1CBB is a protective termination board associated with the TPROS turbine-protection architecture. Its physical role is to terminate, route, and interface protection-related field signals between external turbine equipment and the associated protection electronics. Unlike a controller CPU, the board is primarily an interface and termination assembly (the protection logic itself resides in the connected protection electronics).

This distinction matters during replacement. The TPROS board belongs to a specialized turbine-protection signal chain, and closely related TPRO/TPROS boards are not automatically interchangeable. Current Mark VI documentation shows that protection terminal boards interface with dedicated protection processors and trip circuitry, so the exact board suffix, connected cable set, and protection-system architecture must be preserved in the asset record.

Core Technical Specifications

Publicly available secondary records disagree on several environmental and dimensional details. The 0.8 kg / 180 × 180 × 30 mm values are therefore appropriate for preliminary logistics only, not engineering acceptance.

Global Compliance & Industry Certifications

The should be handled as a component of a turbine protection system, not as an independently certified safety controller.

• CE Mark: Verify the applicable Mark VI/Mark VIe equipment declaration for the complete installed assembly. A CE claim for the cabinet does not automatically establish standalone CE conformity for the loose PCB.
• UL/cUL: Do not record the board as independently UL/cUL Listed without the applicable GE certification evidence.
• ATEX / IECEx: The TPROS board should not be represented as an intrinsically safe device. Hazardous-area suitability depends on the complete turbine protection installation, barriers, enclosures, cabling, and associated certified equipment.
• Marine / DNV: No standalone DNV approval was reliably established for this exact board.
• EMC: EMC requirements should be assessed using the complete Mark VI protection cabinet and approved wiring arrangement.
• Functional Safety: TPROS participates in turbine emergency/protection circuitry, but the board’s physical presence does not by itself establish SIL certification.

This matters in an audit because a protection terminal board may form part of a safety-related trip path even though the PCB itself does not carry the system’s entire safety certification.

Verify specific lot certifications with OEM.

Long-Term Storage & Asset Preservation Guide

Keep the inside an ESD shielding bag. The board’s connectors, terminal interfaces, and discrete electronic components should not be exposed to conductive dust or uncontrolled handling during multi-year storage.

Maintain warehouse humidity below 60% RH where practical. This is a preservation target rather than a statement of the board’s maximum operating humidity. Stable, dry storage helps protect terminal contacts and plated connector surfaces from oxidation.

Do not change field-interface wiring or configuration hardware on a shelf spare. Photograph the original board before any test activity and preserve connector labels, jumper positions, and wire identifiers. A board can pass electrical inspection yet become unusable because its field termination configuration was altered.

Protect connector bodies from impact. Use rigid packaging around the perimeter of the PCB and avoid placing foam directly against fragile connector shells.

Physical Installation Prerequisites

The is a cabinet/panel-mounted Mark VI protection board, not a conventional DIN-rail module. The board should be mechanically installed using the original GE mounting arrangement.

Cabinet clearance: Preserve the original Mark VI mechanical spacing and airflow. Do not invent a universal 50 mm clearance around the PCB when the cabinet drawing defines a different arrangement.

Connector clearance: Leave sufficient space for full connector engagement and cable bend radius. Do not allow field cables to pull laterally on the board-mounted connectors.

Grounding: Follow the Mark VI cabinet protective-earth and signal-shielding arrangement. Protection wiring should not be repurposed as a protective-earth path.

Field wiring: Identify every protection-related cable before removal. A TPROS board sits within a protection signal chain, so a single incorrectly landed conductor can create an apparent trip-system failure.

Environmental control: Keep the cabinet within the validated GE environmental limits for the installed protection system. Avoid condensation, conductive dust, oil mist, and excessive vibration.

Protection circuit isolation: Before disconnecting any turbine protection wiring, follow the site’s approved turbine trip bypass/isolation procedure. Never defeat an emergency trip circuit merely to facilitate board replacement.

Buyer’s FAQ — Logistics & Compliance Focus

Q: What HS Tariff Code should I use for ?
A: A classification under HS 8538.90 is commonly used in secondary trade records for Mark VI terminal/interface boards. However, the final national tariff code depends on the importing jurisdiction and customs interpretation. Provide the broker with the full technical description: GE Mark VI TPROS protective termination board for turbine protection.

Q: What Country of Origin should I declare?
A: Use the actual manufacturing origin supported by the physical label or traceable GE documentation. Secondary inventory records commonly report USA, but that should not replace lot-specific COO evidence. Keep the COO declaration, invoice, packing list, and nameplate photograph together.

Q: Should I insure this board during international shipment?
A: Yes when it supports a production-critical turbine protection system. Although the board is reported at only about 0.8 kg, its replacement scarcity and turbine downtime exposure can be much greater than the freight value. Use ESD packaging, rigid cushioning, moisture protection, tracking, and cargo insurance based on the documented replacement value.

Q: Does the include the latest firmware pre-loaded?
A: No. This is a termination/interface board, not a programmable turbine-control CPU. There is no conventional user firmware package that should be treated as a purchase attribute. Acceptance should focus on exact part identity, hardware revision, connector condition, field-interface compatibility, and electrical integrity.

Q: Can I substitute another TPRO board with the same physical dimensions?
A: No. Mark VI protection boards such as TPROH1C, TPROH2C, and TPROS1CBB belong to related but distinct configurations. Signal allocation, connected protection processors, cable interfaces, and system architecture must be verified before substitution. A physically compatible board is not necessarily functionally compatible.
