Allen-Bradley 1756-IR6I RTD Input Module

We’ve had multiple clients asking about this specific ControlLogix module lately. The 1756-IR6I is Allen-Bradley’s 6-channel RTD input module designed for precision temperature monitoring in industrial settings. Unlike standard thermocouple modules, this one works directly with RTD sensors to provide more stable readings in environments where temperature accuracy matters – think chemical processing plants or food storage facilities.

This module works particularly well in applications where small temperature variations can impact product quality. A recent pharmaceutical client used these in their reactor cooling systems – they needed ±0.5°C accuracy across six different zones. The galvanic isolation between channels was critical for their setup since they had varying ground potentials across the plant.

While technically part of the ControlLogix family, we’ve successfully integrated these with other PLC systems through proper backplane configuration. Common supporting models include the 1756-OB6I output modules and 1756-CFM memory modules. Would you like me to check compatibility with your specific system?
