Allen-Bradley 1769-IR6 CompactLogix RTD Input Module
Configured for high-accuracy temperature acquisition in automated systems, the Allen-Bradley 1769-IR6 (1769-IR6 Analog Input Module) provides direct physical/electrical execution. The module interfaces with up to 6 independent Resistance Temperature Detector (RTD) or direct resistance sensors, converting small ohmic fluctuations into digital temperature data blocks. Operating as a single-slot component, the hardware transfers data across the local backplane assembly to execute precise thermal tracking without external signal converters.

EtherNet/IP Deterministic Networks and Firmware Flash Compatibility
Engineers must ensure firmware flash compatibility across the host CompactLogix 1768/1769 or MicroLogix 1500 controller profiles to secure proper channel scanning. The module routes digitized data points back through the backplane bus, where synchronization rates depend heavily on the total physical I/O density scaling of the local rail assembly. To prevent data corruption within EtherNet/IP deterministic networks, internal Sigma-Delta converters process all 6 active channels within specified time parameters while isolating field noise via a 720 VDC isolation barrier.
Frequently Asked Questions
Q: Can this analog module be hot-swapped while the CompactLogix backplane is energized?
A: No. The 1769 Compact I/O architecture does not support Removal and Insertion Under Power (RIUP). Operators must isolate system power before inserting or extracting the hardware to avoid internal logic corruption or an unrecoverable major controller fault.
Q: Does the module compensate for signal degradation caused by long RTD field wiring runs?
A: The module mitigates line resistance using 3-wire or 4-wire hardware configurations to nullify lead wire impedance. Engineers must ensure total loop cable impedance stays below 25 Ohms, using specified shielded cables to maintain listed measurement tolerances.
Field Installation Guidelines
- Bus Interlocking and Assembly: Mount the module next to the adjacent 1769 chassis unit by aligning the mechanical tongue-and-groove side guides. Push the bus levers forward firmly to lock the integrated backplane connectors together before applying any electrical power.
- DIN-Rail and Panel Attachment: Fix the open-type hardware to an EN 50022 compliant 35 mm DIN rail or bolt it directly to the enclosure panel plate via the retractable mounting feet. Ensure the cabinet environment remains within 5 to 95 percent non-condensing relative humidity parameters.
- Sensor Shield Grounding and Routing: Wire the RTD sensors using independent shielded twisted pairs, keeping the runs clear of high-voltage AC lines or motor drive cables. Ground the cable shields at a single, dedicated termination bar inside the local control panel.
