Product Overview

The IS200TBAIH1CDD is an analog signal termination board built for GE Mark VIe turbine‑control platforms, serving as the physical wiring interface between field transmitters and system I/O processor cards. It features ten analog input channels accepting two‑wire, three‑wire and four‑wire transmitter devices, alongside two configurable analog output channels for closed‑loop process actuation. On‑board filtering circuits mitigate high‑frequency electrical noise common within power‑generation cabinet environments, preserving signal integrity over long field cable runs.

This hardware resolves key pain points for turbine monitoring and retrofit projects: flexible jumper‑selectable signal ranges, native support for both simplex and TMR triple‑modular‑redundant architectures, and integrated fault‑detection logic that isolates faulty output circuits to prevent system‑wide disturbance. Power‑plant maintenance teams, turbine system integrators and legacy‑system upgrade projects benefit most. It routes pressure, flow, temperature and process‑variable measurements back to Mark VIe controllers without custom signal‑conditioning hardware, and supports fast field commissioning through clearly labelled terminal points and shield‑ground connection terminals.

Key Application Notes

• Requires pairing with Mark VIe VAIX / VAIC I/O processor boards for signal digitization; no standalone processing capability
• Jumpers select current‑mode or voltage‑mode input ranges and adjust output current limits
• In TMR configurations, input signals fan out to three redundant control paths while output channels combine driver currents via on‑board measurement shunts
• Conformal coated PCB for improved humidity and airborne‑contaminant resistance in turbine‑control cabinet installations
