Deterministic I/O and TMR Architecture

The IS200TDBTH6A is designed for discrete signal processing within GE Mark VIe industrial control architectures. The terminal board provides 24 isolated discrete inputs and 12 Form-C relay outputs for field device connection, including switches, alarms, and interlock circuits.

The board supports I/O density scaling through integration with PDIO packs and Mark VIe controller configurations. It can operate in simplex, dual modular redundant (DMR), and triple modular redundant (TMR) architectures where synchronized discrete signal processing is required.

The hardware design includes surge suppression networks and input filtering circuits to manage inductive transients and electrical noise. Ribbon cable connection to PDIO packs provides the physical communication path between field terminals and controller processing modules.

Field Installation Guidelines

Install the IS200TDBTH6A according to the GE Mark VIe cabinet wiring layout and PDIO terminal board installation procedures. Confirm ribbon cable connection alignment and secure all terminal connections before system startup.

Use field wiring practices suitable for discrete control circuits. Separate relay output wiring from low-level signal wiring where possible to reduce electrical interference. Connect cable shields according to the cabinet grounding design.

Verify input polarity, wetting voltage source, and relay contact configuration before commissioning. Check controller diagnostics and discrete I/O status feedback after installation to confirm correct signal operation.
