GE IS200TRTDH1C – RTD Input Terminal Board for Mark VI temperature sensing

The GE IS200TRTDH1C is a Mark VI terminal board designed for bringing multiple RTD temperature sensors cleanly into the control system. From my experience, it’s the piece you use when you want reliable, low-noise RTD wiring and straightforward termination—typically on gas/steam turbine and balance-of-plant temperature points where accuracy and uptime matter.

Key Features

• Multi‑channel RTD termination – Typically supports a bank of RTD inputs for cabinet consolidation, reducing panel space and wiring clutter.
• 2‑wire and 3‑wire RTD support – Commonly used with Pt100 and Ni120 sensors in many cases, giving you flexibility across plant standards.
• Low-noise layout with shield management – You might notice that noise pickup is minimized thanks to grounded shield points and short internal runs.
• Passive board (no external power) – Excitation and measurement are handled by the associated RTD interface module, which simplifies cabinet power design.
• Mark VI ecosystem compatibility – Works with GE’s RTD interface modules (VME/IO pack side) for tight integration and diagnostics.
• Field-serviceable screw terminals – Barrier‑type terminals help speed up commissioning and cut troubleshooting time on site.
• Supports redundant architectures – In most cases, can participate in TMR arrangements when paired with redundant RTD interface modules.

One thing I appreciate is how predictable the wiring workflow is—installers usually land shielded pairs, set the RTD wiring scheme (2‑ or 3‑wire), and then cable to the interface module. A maintenance tech told us it noticeably reduced their RTD fault-finding because the terminal labeling and shield bars seemed to be thought through.

Technical Specifications

Related or Supporting Products

• IS200VRTD(H1 series) – RTD interface/processing board that provides excitation and measurement for the TRTD terminal board.
• IS200TRTDH1A / IS200TRTDH1B – Earlier revisions of the same terminal board; the “C” revision typically brings layout or component updates.
• Shield bars and field wiring kits – Useful when upgrading older panels; helps with clean shield termination and noise performance.
• GE Mark VI I/O packs – For systems migrating to mixed architectures, confirm the RTD pack/interface part pairing for your cabinet.

Installation & Maintenance

• Cabinet & mounting – Install on a flat, grounded backplate inside a ventilated control cabinet. Maintain clearance for cable bend radius and service access.
• Wiring – Use twisted, shielded pairs for each RTD. Land shields to the designated shield bar/earth point at one end only to avoid loops.
• RTD configuration – Confirm 2‑wire vs 3‑wire wiring, and keep lead lengths consistent per channel where possible to minimize measurement error.
• Grounding & noise – Bond cabinet ground properly; route RTD cables away from high‑current lines and VFD outputs.
• Routine checks – Periodically re‑torque terminal screws, inspect for oxidation on terminals, and verify shields remain intact.
• Calibration/verification – Sensor calibration is done at the RTD or interface module level; verify scaling and channel health in the Mark VI diagnostics after wiring changes.
• Firmware/logic updates – Not applicable to the terminal board itself, but it’s wise to keep the associated RTD interface module firmware and Mark VI application logic current.

Quality & Certifications

• Manufactured for industrial service; typically supplied from ISO 9001 certified facilities
• CE compliant and UL Recognized components, with RoHS conformity where applicable
• Backed by a 365‑day warranty

If you’re standardizing on Pt100 or Ni120 sensors and want a tidy, serviceable termination point inside a Mark VI cabinet, this board tends to fit well. Most teams like that it’s simple—no surprises during commissioning, and spares are easy to swap when time is tight.
