1-2 Overview
General Description
The 1769-IF4 and -IF8 analog input modules convert and digitally store analog
data for retrieval by controllers, such as the CompactLogix™ or MicroLogix™
1500. The module supports connections from any combination of up to four
voltage or current analog sensors for the 1769-IF4 and up to eight for the
1769-IF8. The high-impedance input channels can be wired as either
single-ended or differential inputs.
The 1769-OF2 output module provides two single-ended analog output
channels, each individually configurable for voltage or current. The
1769-OF8C and -OF8V output modules each provide eight single-ended
analog output channels.
Both modules provide the following input/output types/ranges:
The data can be configured on board each module as:
• Engineering Units
• Scaled-for-PID
• Percent
• Raw/Proportional Data
