GE IS200TDBTH6A Discrete Input/Output Terminal Board

The IS200TDBTH6A is an accessory terminal board designed for GE’s Mark VIe control system, specifically paired with the PDIO (Discrete Input/Output) I/O pack. It serves as a critical wiring interface for discrete input and output signals, facilitating reliable connection between field devices (such as switches, relays, and sensors) and the PDIO module in industrial control scenarios.

As an obsolete model, it has been replaced by the upgraded IS400TDBTH6A terminal board to address sub-component obsolescence. The replacement maintains full form-fit-function compatibility, meaning it can directly substitute the IS200TDBTH6A without requiring modifications to the mounting structure, wiring layout, or system configuration. This ensures seamless upgrades for existing Mark VIe systems, protecting user investments while extending the product life cycle.

The terminal board is part of GE’s modular control system ecosystem, supporting the system’s flexible upgrade philosophy. It enables incremental technology updates without replacing the entire control system, aligning with GE’s extended product life cycle support policy that offers replacement parts availability for up to 10 years post-production.

Core Function: Accessory terminal board for Mark VIe PDIO discrete input/output modules, providing wiring interfaces for discrete I/O signals.

Compatibility: Exclusively paired with Mark VIe PDIO series I/O packs (e.g., IS220PDIOH1A, IS220PDIOH1B).

Replacement Model: IS400TDBTH6A (form-fit-function compatible, no special upgrade considerations required).

Upgrade Nature: Obsolete due to sub-component obsolescence; replacement maintains full compatibility with existing systems.

System Compatibility: Works with Mark VIe control systems, supporting mixed use of old and new technology modules (S1A and S1B series) across different terminal boards within the same system.

Life Cycle Support: Covered by GE’s extended product life cycle policy, with replacement parts and upgrade paths available.

Installation Requirement: No additional preparation or modifications needed for replacement; compatible with existing mounting and wiring configurations.

Software Requirement: No specific minimum ControlST software version required for direct replacement (follows the software requirements of the paired PDIO module).
