GE IS200TDBTH6A Discrete Input/Output Terminal Board

GE IS200TDBTH6A Discrete Input/Output Terminal Board

Configured for contact input and relay output handling in Mark VIe architectures, the GE IS200TDBTH6A (IS200TDBTH6A terminal board) provides direct electrical interfacing for 24 discrete channels and 12 relay outputs through hardware‑filtered input conditioning and isolated wetting‑voltage groups.

Hardware Specifications

Profinet / EtherNet/IP Deterministic Networks

Within GE’s Mark VIe control architecture, the TDBT terminal board aligns with deterministic backplane communication timing used by Profinet and EtherNet/IP networks. Although the board itself is passive, its routing paths support stable I/O density scaling by maintaining predictable propagation delays across discrete channels. Firmware flash compatibility resides at the controller level; the terminal board provides fixed electrical behavior without programmable logic.

Frequently Asked Questions

Q: Can the terminal board be hot‑swapped while the rack is energized? A: Terminal boards are not designed for hot‑swap. Removal or insertion should occur only when the associated rack segment is de‑energized to avoid transient loading on the backplane.

Q: How does the hardware filter affect input response time? A: The hardware filter suppresses high‑frequency noise and surges. It introduces a small, fixed delay typical of passive filtering networks but does not alter nominal contact‑closure detection.

Q: Does AC voltage rejection impact DC wetting‑voltage operation? A: No. The 12 V RMS AC rejection is applied to noise suppression. DC wetting‑voltage operation remains unaffected when supplied within the nominal 24/48/125 V DC ranges.

Field Installation Guidelines

• Maintain correct landing of wetting‑voltage conductors to each isolated input group.
• Bond shielded wiring at a single termination point to reduce induced noise on contact inputs.
• Route relay wiring separately from high‑current solenoid or motor circuits to avoid impedance coupling.
• Verify that the option‑card connector is fully seated before energizing the panel.
• Inspect terminal screws periodically to ensure long‑term mechanical stability.
• Follow GEH‑6721L installation practices for grounding, rack alignment, and cable strain relief.
