Description

GE DS200DTBDG1A Contact Output Expansion Termination Module

Configured for contact output expansion and field signal termination in the Speedtronic Mark V / Mark V LM control system, the GE DS200DTBDG1A (DS200DTBD Contact Output Expansion Termination Module) provides direct electrical execution. The board functions as a termination interface for digital/contact outputs, enabling electrical connection between the controller and external devices including relays, solenoids, and ignition converters.

Firmware Flash Compatibility

The DS200DTBDG1A is designed for operation within the GE Speedtronic Mark V / Mark V LM hardware architecture. Correct board selection requires matching the specified functional revision and approved firmware configuration of the associated controller. The G1A revision identifies the hardware revision of the termination board and should be verified before replacement to maintain compatibility with the installed control cabinet configuration.

The module operates as a termination interface rather than an independent controller. Contact output commands are transferred through the Mark V backplane architecture to the DTBD board, where field wiring is terminated and routed to external output devices. Conformal coating provides additional protection of the PCB against moisture, dust, and industrial contaminants.

Frequently Asked Questions

Q: Does the DS200DTBDG1A generate output signals independently?
A: No. It functions as a termination and expansion module. Output commands originate from the associated Mark V control electronics and are routed through the termination board to connected field devices.

Q: Can the module be replaced while the control cabinet remains energized?
A: Available documentation does not specify hot-swap capability. Replacement should follow the applicable Mark V maintenance procedure with the equipment placed in a safe de-energized state unless the manufacturer explicitly specifies otherwise.

Q: Why is conformal coating applied to the PCB?
A: The conformal coating reduces exposure of PCB conductors and components to moisture, dust, and airborne contaminants commonly encountered inside industrial control cabinets.

Field Installation Guidelines

• Verify the complete part number and hardware revision before installation.
• De-energize the control cabinet according to plant lockout and isolation procedures before removing or installing the board.
• Ensure the module is fully seated in its mounting position and all connectors are correctly aligned before applying power.
• Route field wiring separately from high-voltage or high-current conductors to minimize electrical interference.
• Terminate cable shields according to the grounding practice specified for the Mark V control cabinet to reduce noise coupling.
• Inspect connectors and terminal points for contamination or mechanical damage before commissioning.
• After installation, verify continuity and confirm correct operation of each connected relay, solenoid, or ignition converter through standard commissioning procedures.
