GE IS200TDBSH2A Terminal Board

GE IS200TDBSH2A: Description

The GE IS200TDBSH2A is a RoHS-compliant accessory terminal board designed for integration with the Mark VIe and Mark VIeS Control Systems, specifically paired with PDIO (Discrete Input/Output) modules (e.g., IS220PDIOH1A, IS220PDIOH1B). It serves as a critical interface for discrete input and relay contact output functions in hazardous (classified) and non-hazardous industrial environments, enabling reliable signal transmission between field devices and the main control system.

Engineered to support intrinsic safety (IS) "ic" standards, this terminal board facilitates connections for resistive simple apparatus (such as relay contacts or switches) in hazardous locations, adhering to global classification standards including Class I, Division 2/Zone 2. It features dual functionality: handling discrete inputs with selectable contact wetting power and providing relay contact outputs for control applications. The board is compatible with Euro Style Box-type terminal blocks, ensuring secure wiring with specified screw torques for copper conductors, and supports system redundancy and modular expansion without modifying existing rack infrastructure.

Ideal for industries such as oil & gas, power generation, and manufacturing, the IS200TDBSH2A ensures signal integrity and safety compliance in harsh operating conditions. It works seamlessly with GE’s 3500 Series-like modular philosophy, integrating with the Mark VIe system’s power distribution boards (e.g., JPDS, JPDG) and configuration software for parameterization, alarm setup, and diagnostic monitoring.
