Channel-to-Channel Isolation and Analog Signal Processing

The IS200WETAH1AEC provides analog signal interface functions for GE Mark VI and Mark VIe control architectures. The module supports channel-to-channel isolation for mixed sensor input configurations, reducing interaction between independent measurement circuits during temperature, pressure, and position signal acquisition.

The module integrates analog conversion functions with selectable input processing paths for voltage, current, RTD, and thermocouple sensors. Cold junction compensation (CJC) processing supports thermocouple measurement accuracy, while filtering functions reduce signal disturbances from industrial electrical environments.

Field Installation Guidelines

Install the IS200WETAH1AEC according to GE Mark VI/Mark VIe system installation procedures. Verify the 24 VDC supply connection, module mounting position, and terminal wiring before system startup.

Use shielded cables for low-level analog signals and connect cable shields according to cabinet grounding practices. Keep sensor wiring separated from high-current power cables and switching circuits to minimize electromagnetic interference.

Verify RTD wiring configuration, thermocouple polarity, and current loop connections during commissioning. Perform channel diagnostics and signal validation through the control system interface after installation.
