GE Electric | IS200WETAH1AEC | Analog Input Termination Board
IS200WETAH1AEC Product Overview
Functional Description:
The GE IS200WETAH1AEC is a High-Density Analog Input Termination Board designed for GE Mark VIe turbine control systems. It provides signal conditioning, isolation, and terminal interfacing for analog sensors (e.g., temperature, pressure) by converting field signals to digital data for the controller.

Product Series
- Member of Mark VIe I/O Termination Assembly Series (compatible with IS200/EX2100 hardware).
Key Features
- Universal Input Support: Auto-ranges between voltage/current/RTD/thermocouple signals.
- EMC Shielding: Conductive coating (suffix “EC”) for RFI/EMI immunity per IEC 61326.
- Open-Wire Detection: Alerts on broken sensor connections.
- Hot-Swappable: Tool-less replacement via DIN rail mounting.
- Diagnostic LEDs: Per-channel health monitoring (green/red status).
- Surge Protection: TVS diodes on all inputs (compliant with IEEE C37.90.1).
Functions & Roles
- Sensor Interface: Connects PT100/PT1000 RTDs, J/K/T-type thermocouples.
- Signal Linearization: Converts nonlinear TC/RTD curves to digital values.
- Noise Filtering: 50/60 Hz notch filtering for industrial environments.
- Cold Junction Compensation: Integrated for thermocouple inputs.
- Ground Isolation: Prevents ground loops in distributed systems.
