GE DS200TCRAG2A — Speedtronic Mark V RST Contact Relay Input Board (TCRI) for Gas Turbine Control

Meta Description

GE DS200TCRAG2A contact relay input board for Speedtronic Mark V gas turbine control systems. Provides discrete/relay I/O in R1/R2/R3 I/O cores and works with the TCRI terminal assembly. Legacy/discontinued Mark V component.

Product Core Overview

The DS200TCRAG2A is a GE Speedtronic Mark V series I/O board used in gas and steam turbine control systems. It is an RST board installed in I/O cores R1, R2 and R3, and is commonly associated with the TCRI contact relay input assembly.
The board handles discrete/relay-type signals between the turbine field devices and the Mark V control processors. In many systems it works together with the TCQA analog I/O board, which scales and conditions LVDT, servo, thermocouple, 4–20 mA, vibration, pulse and generator/line signals. The TCQA board exchanges data with the STCA board through the 3PL data bus and with the TCQC board through the JE connector.
DS200TCRAG2A is a legacy/discontinued Mark V component and is typically available as surplus, refurbished or tested used stock.

Quality Control Procedures

  • Part number verification: Confirm DS200TCRAG2A, revision suffix and serial number.
  • Visual inspection: Check PCB condition, connectors, jumpers, fuses, LEDs and terminal blocks.
  • Connector inspection: Verify all I/O and backplane connectors for damage, corrosion or bent pins.
  • Power-up test: Confirm LED indicators and board initialization under safe test conditions.
  • Discrete I/O check: Validate relay/contact input and output channels against the system configuration.
  • System communication check: Verify data exchange with STCA/TCQA/TCQC boards where applicable.
  • Documentation traceability: Record revision, jumper settings, test results and replacement history.

Frequently Asked Questions

What is the DS200TCRAG2A?
It is a GE Speedtronic Mark V RST I/O board used for contact relay/discrete I/O in gas turbine control systems.
Where is it installed?
It is installed in the Mark V R1, R2 and R3 I/O cores and is associated with the TCRI contact relay input assembly.
How does it differ from DS200PTBAG1B?
DS200TCRAG2A is a contact relay/discrete I/O board, while DS200PTBAG1B is an RST analog I/O board (TCQA) handling LVDT, servo, thermocouple, 4–20 mA and vibration signals.
Can it be replaced directly?
Only after confirming the full suffix, revision, connector layout and jumper settings. Mark V boards may differ by revision, so OEM documentation should be checked before replacement.
Is this board still produced by GE?
No. DS200TCRAG2A is a legacy/discontinued product and is typically supplied as surplus, refurbished or tested used stock.

Installation and Configuration Guide

  1. Confirm identity: Read the full part number, revision and serial number from the original board label.
  2. Isolate power: De-energize the Mark V control cabinet and follow lockout/tagout procedures.
  3. Record existing setup: Photograph connector positions, jumper settings, ribbon cables and terminal wiring.
  4. Label wiring: Mark all signal wires and connectors before removal to avoid miswiring.
  5. Handle with ESD protection: Use an anti-static wrist strap when handling the PCB.
  6. Install the board: Mount the DS200TCRAG2A into the correct R1/R2/R3 core slot and secure all mounting hardware.
  7. Reconnect wiring: Restore all I/O, backplane and terminal connections exactly as documented.
  8. Power-up and test: Restore power, verify LEDs, validate discrete I/O channels, and confirm communication with related boards under supervised testing.
