- Accepts documented RTD and resistance inputs for PLC-5 temperature measurement
- Uses configurable sensor type, excitation and engineering-unit conversion
- Depends on correct RTD lead compensation, shielding and channel calibration
1771-IR is an Allen-Bradley RTD input module for measuring temperature and resistance through a 1771 I/O chassis.
Its accuracy depends on the selected RTD curve, lead-wire arrangement and channel configuration rather than the sensor resistance alone.
Preserve sensor type, wiring, scaling, alarm limits and calibration records before exchanging the module or field termination.
Availability, condition, price, and shipping time for 1771-IR are confirmed during quotation.

- Select the documented platinum or copper RTD curve for temperature conversion
- Use resistance mode when automatic RTD linearization is not applicable
- Preserve the selected Celsius or Fahrenheit engineering-unit format
- Follow the three-wire RTD diagrams to support lead-resistance compensation
- Route shields and grounds according to the official installation instructions
- Keep channel assignments and field-wiring-arm terminals consistent during replacement
- Confirm the saved block-transfer configuration before calibration
- Allow the module and sensors to reach stable operating conditions
- Verify all channels against the application accuracy requirement after replacement
- Platinum RTD temperature measurement
