GE Fanuc 8106-TI-RT PAC8000

Built for Multi-Point RTD Measurement

The GE Fanuc 8106-TI-RT is a PAC8000 process I/O module designed to acquire signals from four RTD or resistance sources. It is part of the 8000 Process I/O family and is intended for industrial control systems that require dependable temperature measurement and process monitoring.

Unlike a general-purpose voltage or current input module, the 8106-TI-RT is specifically configured around temperature and resistance measurement. This makes it appropriate for applications where RTDs are used to monitor equipment, process lines, vessels, machinery, or other temperature-sensitive assets.

The published PAC8000 technical documentation specifies four RTD/resistance inputs and identifies the module as suitable for safe-area or Zone 2/Division 2 installations when the appropriate system requirements are followed.

Flexible RTD Configuration

A major advantage of the 8106-TI-RT is its support for different RTD wiring arrangements. The module accommodates two-wire, three-wire, and four-wire RTD configurations, allowing engineers to select the appropriate connection method for the sensor and accuracy requirements.

The module can be configured for supported sensor types, while input filtering can be selected according to process conditions. The available filtering options include no filtering, two-reading averaging, and running averaging.

For applications involving broken or disconnected sensors, the module also provides open-circuit detection. An upscale response can be configured where required by the control strategy.

PAC8000 Integration

The 8106-TI-RT operates as part of the PAC8000 modular I/O system. The module's acquired measurements are processed and transferred through the system's Railbus architecture, allowing temperature data to become part of the wider process-control application.

The PAC8000 family includes a broad selection of analog, discrete, pulse, safety, and specialty I/O modules. The 8106-TI-RT therefore provides a dedicated temperature-input option within a larger modular control architecture.

Typical Uses

This RTD input module can be used wherever multiple temperature signals need to be collected by an industrial automation system. Common applications include:

Process temperature monitoring: measuring temperatures in pipelines, tanks, reactors, and production equipment.

Equipment protection: monitoring motors, pumps, compressors, bearings, and other assets.

Industrial heating: collecting feedback from heaters, furnaces, ovens, and thermal processing systems.

Power and utilities: monitoring temperatures throughout auxiliary and process equipment.

General automation: integrating multiple RTD sensors into a PAC8000-based control or remote I/O installation.

Maintenance and Replacement Notes

For replacement work, technicians should confirm the module's complete part number and compare the existing wiring and configuration before installation. The RTD sensor type and connection method should also be checked because incorrect wiring can produce inaccurate temperature readings.

Regular maintenance should include inspection of field terminals, sensor cables, connectors, and module status. When troubleshooting, compare the affected channel with a known-good channel where possible. A temperature measurement problem may originate from the sensor or field wiring rather than the 8106-TI-RT itself.

The GE Fanuc 8106-TI-RT remains a practical choice for maintaining compatible PAC8000 installations that require four-channel RTD or resistance measurement, particularly where existing system architecture needs to be preserved.
