Description

The General Electric DS200TCDAH1BHE is a Digital I/O Board developed for use in the GE Speedtronic Mark V Series turbine control systems. The DS200TCDAH1BHE processes and routes digital signals, handling contact input signals from the DTBA and DTBB terminal boards as well as contact output signals (relay/solenoid) from the TCRA boards. These signals are conditioned, time-tagged upon state changes, and transmitted over the IONET communication network to the TCQC board in cores and (if is installed) and the CTBA terminal board in . Designed for steam, gas, or wind turbine control and management applications, the board is typically installed in digital I/O cores , , and .

Features

• Processes contact inputs from DTBA and DTBB terminal boards via JR and JQ connectors.
• Conditions input signals and applies time-tags to state changes.
• Processes contact output (relay/solenoid) signals from TCRA boards.
• Transmits conditioned digital signals across the IONET network via JX1 and JX2 connectors.
• Supports software-based contact signal inversion using I/O configuration constants.
• Equipped with eight hardware jumpers for configuration, testing, and network setting.
• Features an on-board block of 10 LEDs and a side LED for diagnostic indications.
• Includes dedicated test points for manual signal probing and circuit diagnostics.

Applications

• GE Speedtronic Mark V Gas Turbine Control Systems
• GE Speedtronic Mark V Steam Turbine Control Systems
• GE Wind Turbine Control Management Systems

Installation Guidelines

• IONET Termination: Set jumpers J2 and J3 to control IONET termination resistors based on network topology requirements.
• Board Identification: Configure jumpers J4, J5, and J6 to set the unique IONET ID for proper network addressing and communication.
• System Functions: Set jumper J7 to enable or disable the stall timer function according to specific system control needs.
• Factory Settings: Keep jumpers J1 and J8 in their default factory positions unless executing specific test procedures.
• Signal Probing: Utilize calibrated test probes compatible with the board test points when analyzing circuit voltage or verifying input/output signals.
• Thermal Protection: Maintain adequate enclosure cooling, as thermal trip protection automatically shuts down the drive system upon detecting an interior over-temperature condition.
