GE DS200TCTGG1AFF – TCTG Trip/Protection I/O Interface Board for GE Mark V (DS200) Cabinets

The GE DS200TCTGG1AFF is a TCTG series interface board used in Mark V (Speedtronic) and DS200-based control cabinets. It serves as a trip/protection I/O interface, coordinating discrete signals between the control core and the cabinet’s terminal hardware—things like start/stop chains, permissives, and trip paths. From my experience, plants keep a G1/AFF spare on hand because when these cards age, you may see start-permit “chatter”, delayed interlocks, or nuisance trip indications, especially after heat soak. You might notice the keyed harness headers and clear silkscreen—maintenance can usually do a like-for-like swap fast without disturbing field wiring.

Company’s Order Placement Process and Guarantees

• Warranty period: 365 days
• Delivery time: 1 week for in-stock; no more than one month at the latest
• Payment method: 50% advance payment; full payment for delivery
• Express delivery methods: FedEx / UPS / DHL
• Compatibility check: Send the panel nameplate and a clear photo of the DS200TCTGG1AFF label; it typically locks the correct group/revision on the first pass.

Key Features

• Trip/permissive interface – Routes discrete outputs and reads status returns so interlocks and trip logic behave consistently.
• Deterministic sequencing – Supports start/stop chains with predictable timing across the Mark V stack.
• Group G1, rev. AFF – Hardware group and revision matching matter; we help verify against your cabinet build.
• Drop-in replacement – Like-for-like spare that typically preserves harness routing and parameterization.
• Service-friendly mechanics – Keyed connectors, labeled headers, and accessible standoffs keep the changeout short.
• Lifecycle extension – Stabilizes legacy GE panels without committing to a full retrofit project.

Technical Specifications

Application Fields

Typically installed in GE Mark V turbine control panels (gas/steam) and DS200‑based exciter/drive cabinets across power generation, oil & gas compressor stations, paper & converting, and metals processing. A common scenario is intermittent start‑permit drops or sticky interlocks after heat soak—replacing DS200TCTGG1AFF usually restores stable discrete I/O behavior without altering PLC logic or field wiring.

Advantages & Value for Procurement

• Reliability – Brings back clean interlock timing and consistent trip/permissive handling, cutting nuisance alarms.
• Compatibility – Purpose‑built for DS200/Mark V; we confirm group (G1) and revision (AFF) to match your panel.
• Cost control – Board‑level maintenance is typically far cheaper than a cabinet retrofit and shortens re‑commissioning.
• Predictable downtime – Drop‑in mechanics and labeled connectors keep the changeout inside a tight outage window.
• Technical backup – Help with harness mapping, revision matching, and post‑swap checks to lower risk.

Installation & Maintenance

• Cabinet environment – Clean, dry, ventilated enclosure; ambient 0…55 °C; avoid condensation and conductive dust.
• Safety & isolation – Lockout/tagout, wait for DC bus discharge, and verify zero energy before handling.
• ESD precautions – Use an antistatic wrist strap; handle by PCB edges and avoid touching component pins.
• Harness seating – Mark positions, fully seat keyed connectors, and confirm PE/ground continuity and strain relief.
• Post‑swap checks – Validate permissives and interlock timing, then run a controlled start while monitoring alarms/logs.
• Routine care – Annual dust cleaning, connector inspection/re‑seating, and periodic log review; any firmware tasks live on companion control boards.

Quality & Certifications

• Used within CE‑conformant control systems; the module forms part of the certified assembly.
• UL recognition typically applies at the complete cabinet level.
• RoHS‑aligned materials/processes in many cases for GE electronic spares.
• Manufactured under ISO 9001 quality systems at the OEM level.
• Warranty: 12 months (365 days) against functional defects under normal operation.
