Configured for discrete contact interfacing in Mark VIe and VIeS platforms, the GE IS200TDBTH2A terminal board provides direct electrical execution of 24 V DC contact inputs and relay‑type outputs through DIN‑rail mounted surface‑mount circuitry.
Within GE’s Mark VIe/VIeS control architecture, the TDBT‑series terminal boards align with deterministic backplane timing used by Profinet and EtherNet/IP networks. Although the IS200TDBTH2A is passive, its routing paths maintain predictable propagation delays across discrete channels, supporting stable I/O density scaling. The board’s electrical behavior is fixed; firmware flash compatibility resides entirely at the controller and PDIO pack level.
Frequently Asked Questions
Q: What I/O pack can the IS200TDBTH2A operate with? A: The terminal board is compatible with the PDIO I/O pack for discrete signal processing.
Q: Is there an option board that can connect to the IS200TDBTH2A? A: Yes. The IS200WROB option board can be installed to provide sensed and fused power distribution to the first six outputs, with dedicated power routing to the final output.
Q: Can the terminal board be inserted or removed while energized? A: Terminal boards are not designed for hot‑swap. Removal or insertion should occur only when the associated rack or DIN‑rail segment is de‑energized.
Field Installation Guidelines
Mount the board on a stable DIN rail to ensure proper connector alignment.
Maintain shield bonding at a single termination point to reduce noise on contact inputs.
Route relay wiring separately from high‑current solenoid or motor circuits to avoid impedance coupling.
Verify correct landing of 24 V DC supply conductors and ensure polarity consistency across input groups.
Confirm option‑card seating (IS200WROB) before energizing the panel.
Inspect terminal screws periodically to maintain long‑term mechanical stability.
