GE IS200TDBTH6ABC Terminal Board – Reliable field I/O termination for GE Mark VI turbine control

The GE IS200TDBTH6ABC is a Mark VI series terminal board built for dependable field signal termination inside GE turbine control panels. From my experience, this style of IS200 terminal board is used to bring plant wiring (sensors, switches, and auxiliary devices) into the control system cleanly and consistently, while the mated I/O card handles the signal conditioning. You might notice that later H6/ABC revisions like this one typically carry incremental improvements in manufacturability and EMC robustness, yet remain functionally compatible within the same Mark VI group.

Key Features

• Purpose-built for Mark VI cabinets – Provides organized, labeled field termination for sensors and discrete devices inside GE Mark VI control enclosures.
• Passive board (no separate power) – In most cases the board is passive and relies on the mated I/O module; that keeps wiring straightforward and troubleshooting simpler.
• Shielded, barrier-type terminations – Typically supports ring/fork-lug or ferrule wiring with clear channel grouping to reduce crosstalk and wiring errors.
• Robust cabinet integration – Panel/standoff mounting with earth bond points for proper grounding; designed for industrial temperature ranges and continuous operation.
• Revision H6ABC lineage – Later GE revisions generally incorporate component updates and layout refinements that, in many cases, improve long-term reliability.
• Service-friendly layout – Field wiring, identification, and access for maintenance are arranged so techs can check torque, re-terminate, or replace quickly.

Related or Supporting Products

• GE IS200TBTCH1C – Dedicated thermocouple terminal board with integrated cold-junction compensation; ideal when you need precise temperature inputs.
• GE IS200TBCIH1A – Contact input terminal board for 24 Vdc wetting; suited for dry-contact/discrete status signals.
• GE IS200TBQEH1C – Proximitor/speed or transducer-oriented terminal board used in many vibration/speed pickup applications.
• GE I/O interface cards (Mark VI family) – Mates with terminal boards via GE cables; select the I/O card based on your required signal type and channel density.

One thing I appreciate is how these terminal boards keep the cabinet tidy. A maintenance lead told us the later H-revision board “seems to be less sensitive to noise” after they re-terminated a mixed analog/discrete bundle—simple, but it made the troubleshooting day much easier.

Installation & Maintenance

• Cabinet standards – Install in a clean, dry, ventilated Mark VI cabinet. Maintain ambient 0–60 °C and avoid strong EMI sources; segregate high-voltage cabling from low-level analog.
• Grounding & shielding – Bond the board’s ground to cabinet earth. Route shields to the designated shield bar or terminal point; avoid ground loops by single-point grounding practices.
• Wiring – Use the recommended wire gauge per GE manual (often 18–22 AWG). Keep lead lengths consistent for low-level signals. Torque-check terminal screws during commissioning and at scheduled outages.
• Verification – After landing field wires, perform continuity and polarity checks. For mixed-signal terminations, label and dress cables to maintain spacing between discrete and analog runs.
• Routine maintenance – No firmware on the terminal board. Inspect connectors each outage, re-seat ribbon cables if needed, clean dust with ESD-safe method, and re-check terminal torque. Replace any discolored or damaged terminals promptly.
• Spare strategy – Keep at least one board per cabinet as a spare; in many cases swap time is under an hour when wiring is well-labeled.

Quality & Certifications

• Manufactured within GE’s quality system (ISO 9001 at the corporate level).
• Typically CE compliant for industrial control panels; UL recognition is common for this hardware family.
• RoHS status may depend on specific revision and production lot; we can verify per serial before shipment.
• Supplier warranty: 365 days; tested prior to dispatch and packed for ESD protection.

If you’re updating a mixed I/O bay or replacing an aging terminal block in a Mark VI cabinet, the IS200TDBTH6ABC is a practical, drop-in path. It fits the existing ecosystem, and in many cases, reduces field rework because the wiring conventions match what your technicians already know.
