Allen-Bradley 1769-IF4 Analog Input Module Overview

The Allen-Bradley 1769-IF4 is a 4-channel analog input module for CompactLogix systems. This module works with MicroLogix 1500 and 1769 CompactLogix controllers. The Allen-Bradley 1769-IF4 accepts both current and voltage input signals on each channel. Each of the four inputs can be configured individually for differential or single-ended operation. The module uses a Delta-Sigma converter type for accurate analog-to-digital conversion. The Allen-Bradley 1769-IF4 has a resolution of 14 bits for unipolar signals and 14 bits plus sign for bipolar signals. This module does not provide loop power for analog inputs. An external power supply must match your input transmitter specifications.
