Features:
- The Allen-Bradley 1769-IR6/A Compact I/O RTD/Resistance Input Module serves as the interface between field RTD/resistance sensors and the compact I/O rack backplane.
- Each channel on the 1769-IR6/A can be independently configured via software for 2-wire or 3-wire RTD operation, or for direct resistance measurement, providing flexible adaptation to diverse sensor wiring requirements.
- The 1769-IR6/A communicates directly through the 1769 backplane, distributing converted digital data to the controller's graph table without requiring additional communication interfaces.
When the 1769-IR6/A is configured as an RTD input, it supports seamless linearization, directly converting sensor readings to temperature values in degrees Celsius (°C) or degrees Fahrenheit (°F). When configured as a resistance input, the 1769-IR6/A converts the voltage to a linear resistance value in ohms if the input signal is linear before entering the module.
The 1769-IR6/A provides essential input functions critical to temperature and resistance monitoring paths, directly affecting the accuracy and reliability of process measurements within the overall control system. One 1769-IR6/A module occupies a single slot in the 1769 chassis and can be installed in any I/O slot position following the controller and power supply modules. For applications requiring more than six channels, additional 1769-IR6/A modules can be added to the same chassis up to the controller's maximum I/O capacity.
For comprehensive fault detection applications, the 1769-IR6/A provides built-in diagnostic capabilities on each channel. In addition to standard signal conversion, the 1769-IR6/A performs automatic monitoring for open-circuit conditions (all wires), short-circuit conditions (excitation and return wires only), and over-range or under-range signal levels. The 1769-IR6/A diagnostic system continually evaluates the health of each input channel.
The 1769-IR6/A Allen-Bradley Compact I/O RTD/Resistance Input Module may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
- Thermal Process Tracking: Monitors heat baselines in industrial ovens, chemical batch reactors, and manufacturing molds.
- Sensor Compatibility: Supports standard 2-, 3-, or 4-wire Platinum, Nickel, Nickel-Iron, or Copper RTD elements.
- Mechanical Displacement: Measures direct resistance (0 to 3000 ohms) from physical linear slidewires, strain gauges, and potentiometers.
- Equipment Safety: Tracks internal bearing and winding temperatures in large electric motors or compressors to prevent overheating.
- Fault Diagnostics: Signals immediate system alarms for open-circuit, short-circuit, and over-range or under-range sensor failures.
- Chassis Backplane: Links directly to adjacent hardware modules using a built-in, slide-in tongue-and-groove integrated bus lever.
- Direct PLC Control: Integrates as local expansion hardware for CompactLogix controllers or MicroLogix 1500 processor assemblies.
- Network Adapters: Connects to remote plant-wide networks when paired with a 1769-AENTR Ethernet adapter or 1769-ADN DeviceNet module.
- Data Transfer: Moves scaled digital values directly into the input image table memory of the host processor.
- Distance Limits: Requires placement within a specific number of slots from the system power supply to prevent voltage drops.
- Factory Microcode: Uses hardcoded operational logic embedded on the internal microchip, meaning the physical hardware rarely receives field updates.
- Software Configuration: Deploys and manages channel settings using Rockwell Automation's Studio 5000 Logix Designer or RSLogix 5000.
- Module Profiles: Connects to software via specific Add-On Profiles (AOP) or uses a Generic 1769 Module profile definition.
- Host Updates: Receives operational bug fixes by updating the firmware of the connected CompactLogix PLC or Ethernet adapter.
