Symptoms of Failure:
Common failure symptoms for the 1771-IR module include erratic temperature readings and loss of communication with the PLC. To test the module, ensure proper wiring connections to the RTD sensors and check for any visible physical damage on the module.
Facilities may choose to buy a replacement 1771-IR module instead of upgrading due to its compatibility with the Allen Bradley PLC-5 series, commonly used in legacy systems for temperature control applications. Maintaining the legacy architecture with the 1771-IR is cost-effective as it eliminates the need for a complete system overhaul and reprogramming.
