Allen-Bradley 1756-IR6I Isolated RTD Input Module

The Allen-Bradley 1756-IR6I is a 6-channel isolated RTD input module designed for ControlLogix I/O racks, delivering six isolated RTD inputs for precise temperature measurement in industrial automation. It supports RTD sensors in 2-wire, 3-wire, and 4-wire configurations, with channel-to-system isolation for noise immunity and power supplied via the ControlLogix backplane. Mount this module in a ControlLogix I/O rack to feed RTD temperature data into PLC logic for feedback loops, safety limits, and process control across process plants, manufacturing lines, water and wastewater facilities, HVAC systems, ovens and furnaces, and chemical processing equipment. Operating under industrial-rated conditions and installed within an automation enclosure, the 1756-IR6I is a reliable RTD sensing solution; common replacements include the Allen-Bradley 1756-IT6, 1734-IR8, and 1769-IR4 modules.
