1769-IF16C 16-Channel Analog Current Input Module 0-20mA | Allen-Bradley

The Original New Allen-Bradley 1769-IF16C 16-Channel Analog Current Input Module is a high-density analog input module for the CompactLogix and MicroLogix 1500 systems. It accepts 0–20 mA and 4–20 mA current signals from field transmitters and sensors, providing 16 single-ended input channels with 16-bit resolution for precision process monitoring and control. Part of the Bulletin 1769 Compact I/O™ platform, this module can be used as local I/O with CompactLogix controllers or as distributed I/O over EtherNet/IP networks.

Core Engineering Highlights:
16 single-ended analog current inputs | 0–20 mA & 4–20 mA input ranges | 16-bit unipolar / 15-bit + sign bipolar resolution| 180 mA @ 5.1V / 70 mA @ 24V current draw| 500V AC isolation (output group to bus)| 0°C to 60°C operating temperature| DIN rail or panel mount
