RTD Signal Acquisition and Machinery Monitoring
The 102566-02 receives resistance-based temperature signals from connected RTD elements. It supports Pt100, Pt500, and Pt1000 sensor types and converts the measured resistance into temperature data.
With eight input channels, the module can process multiple temperature points within the same monitoring arrangement. The specified measurement range extends from -200 deg C to +850 deg C, while the stated resolution is 0.1 deg C.
For machinery monitoring, RTD inputs can represent temperatures at bearings, gearboxes, motor windings, or other monitored points. Therefore, correct RTD type selection and sensor wiring are required to maintain the stated measurement characteristics.

Field Installation Guidelines
- Verify the module part number and RTD sensor type before installation.
- Match each field RTD element with the corresponding input channel configuration.
- Keep RTD signal wiring separated from high-voltage power conductors and high-current switching circuits.
- Use appropriate shielded instrumentation cable where the installation requires noise control.
- Terminate cable shields according to the site grounding scheme and the applicable system installation documentation.
- Verify polarity, terminal assignment, and continuity before energizing the module.
- Confirm the nominal 24 VDC supply before applying power.
- Check the installed sensor range against the required temperature measurement range.
- After wiring, verify each channel with the connected RTD before placing the measurement point into service.
