The GE IS200TDBSH6A, also cataloged as the TDBSH6A discrete simplex terminal board, provides high‑density discrete‑signal termination for Mark VI turbine‑control architectures. The board executes passive routing of contact inputs and outputs through dual 48‑point terminal blocks and a single 37‑pin DC backplane connector, supporting simplex discrete‑I/O applications.

Profinet / EtherNet/IP Deterministic Networks
As a GE Mark VI discrete‑termination component, the TDBSH6A aligns with deterministic I/O‑pack timing and cabinet‑level wiring practices:
EtherNet/IP deterministic behavior — predictable negotiation windows for CIP‑based traffic.
I/O density scaling — consistent propagation delay across expanded discrete‑monitoring node counts.
Firmware flash compatibility — TDBSH6A remains passive; discrete signals are conditioned by downstream I/O packs.
Frequently Asked Questions (FAQ)
Q: What does the IS200TDBSH6A do? A: It terminates discrete wiring for simplex Mark VI control systems, routing signals through two 48‑point terminal blocks and a 37‑pin connector.
Q: What are terminal blocks used for? A: Terminal blocks terminate individual wires and connect them to circuits or control systems.
Q: Does WOC provide warranty support? A: Yes. UNUSED and REBUILT units can be supplied with up to a 24‑month warranty.
Field Installation Guidelines
Mount the board securely to prevent vibration‑induced connector movement.
Maintain separation between discrete wiring and high‑current conductors to reduce induced noise.
Ensure proper torque on TB1/TB2 screw terminals to avoid intermittent contact faults.
Keep the 37‑pin connector fully seated for stable backplane communication.
Label terminal connections to simplify maintenance and reduce troubleshooting time.
Avoid flexing the PCB during installation; use strain relief on wiring bundles.
