GE DS200TCPAG1AJD Turbine Control Processor Board – Core Processing for Speedtronic Mark V Control

• Warranty period: 365 days

• Delivery time: 1 week for in-stock; no more than one month at the latest

• Payment: 50% advance payment; full payment prior to delivery

• Express delivery: FedEx, UPS, DHL

• Turbine CPU core – Executes Mark V control, sequencing, protection, and monitoring logic.

• Backplane integration – Interfaces directly to the Mark V rack, minimizing field rewiring or configuration drift.

• Supports TMR architectures – Designed to operate within R/S/T redundant cores for high availability in critical turbine applications.

• On-board diagnostics – Status LEDs and internal self-tests help maintenance teams identify issues faster.

• Revision AJD – G1 hardware series with AJD revision level for improved stability and component lifecycle in many panels.

• Form-fit-function compatible – Typically drop-in for existing DS200TCPAG1x variants when matched to the site configuration and firmware level.

This board is typically used in:

• Gas and steam turbine generator sets in power plants

• Mechanical drive turbines for compressors and pumps in oil & gas

• Industrial cogeneration and process steam units

• Retrofit and life-extension projects where Mark V remains the control standard

A maintenance lead from a combined-cycle site summed it up simply: “Swapped in the DS200TCPAG1AJD during an outage; matched our R/S/T build, passed checks, and we were synced back on schedule.”

• Reliability in critical service – Built for the Mark V environment, with stable operation in TMR cores.

• Compatibility – Works with established Mark V I/O stacks and HMIs, helping avoid requalification of field wiring.

• Reduced downtime – Drop?in form factor and known commissioning steps typically shorten maintenance windows.

• Lifecycle support – Availability of tested, warrantied units helps sustain legacy fleets without accelerated migration.

• Cost control – Replacing a single board is usually more economical than a full control system upgrade.

• Environment – Install in a clean, dry Mark V cabinet with adequate ventilation. Keep ambient 0–50 °C, non-condensing.

• ESD handling – Use wrist straps and ESD-safe procedures; handle by edges and standoffs only.

• Seating & connectors – Power down, inspect the backplane, then insert evenly to avoid bent pins. Verify all ribbon and edge connectors are latched.

• Grounding – Ensure panel grounding is intact; poor earth can cause nuisance trips or comms faults.

• Firmware & configuration – After installation, confirm the correct firmware/config for the unit and perform standard Mark V diagnostic checks before turbine restart.

• Routine care – Periodic dust removal with dry, oil-free air; visual inspection of capacitors and headers; review event/alarm logs; schedule checks during planned outages.

• Manufactured to GE industrial quality standards; many units used in regulated power environments

• CE and UL typically addressed at the system/cabinet level; board-level compliance aligns with Mark V practice

• ISO 9001 quality management in the supply chain where applicable

• RoHS: legacy exemptions may apply due to original production era

• Warranty: 365 days replacement/repair coverage

For spares planning, sites commonly pair the DS200TCPAG1AJD with:

• GE DS200TCQAG1A – Control/analog interface board working alongside the CPU functions

• GE DS200TCDAH1A – Digital I/O interface within the Mark V core

• GE DS200TCCAG1A – Core communication/control card in many R/S/T racks

One thing I appreciate is how these boards, when kept as a matched set, tend to reduce commissioning surprises. If you share your existing part revisions, we can check cross-compatibility before shipment.
