The Allen Bradley 1771-IFM module is an input module focused on capturing fast millivolt measurements. Designed with eight differential input channels, it is suitable for low-level signal input. This module can handle a voltage range from 0 to 50 mV. With a 12-bit binary resolution, it delivers high precision in data acquisition. The linearity and repeatability are both maintained within ±1 LSB, ensuring reliable performance.

Behavior of the analog-to-digital converter in this module provides a monotonic output, which is crucial for consistent readings. In terms of temperature parameters, the 1771-IFM operates effectively within a minimum and maximum operating temperature of 0 °C and 40 °C, respectively. It exhibits the same temperature constraints for storage, confirming its reliability under varied environmental conditions.
