Allen-Bradley 1769-IF4 4-Channel Analog Input Module

The Allen-Bradley 1769-IF4 is a four-channel analog input module for CompactLogix and MicroLogix systems that provides precise voltage and current measurements from field instruments with 16-bit resolution per channel. Each channel supports selectable input types—0–10 V or ±10 V for voltage, and 0–20 mA or 4–20 mA for current—over the 1769 Compact I/O backplane. It mounts on the 1769 Compact I/O backplane with DIN rail or panel-mount options within the system and is compatible with CompactLogix and MicroLogix controllers. Typical applications include monitoring sensors in water and wastewater treatment, HVAC control panels, batching and dosing equipment, packaging lines, and other manufacturing processes requiring reliable multi-channel analog data. Operating temperature range is 0°C to 60°C. Common replacements include Allen-Bradley 1769-IF8, Allen-Bradley 1746-NI4, and Siemens 6ES7 331-7KF02-0AB0.
