Temperature Input Module

The Allen-Bradley 1794-IR8 is an 8-channel RTD input module from the FLEX I/O system, designed for high-precision temperature measurement in industrial automation. It accepts 2, 3, or 4-wire RTD sensors including Pt100, Pt200, Pt500, Ni100, Ni120, Ni200, Ni500, and Cu10, with 16-bit resolution and industry-leading accuracy.

The Bachmann PTAI216 (order number 00010708-00) is an analog input module from the Bachmann M1 automation system series, designed for direct connection of resistance temperature detectors (RTDs). Bachmann electronic (Austria) manufactures rugged automation controllers widely used in wind energy, marine, power generation, and industrial machinery. The PTAI216 provides temperature measurement channels for PT100/PT1000 sensors. The exact specifications must be confirmed against official Bachmann documentation.
