Allen-Bradley 1769-IF8 8-Channel Analog Input Module

Allen-Bradley 1769-IF8 CompactLogix 8-channel analog input module provides eight differential or single-ended inputs for reading DC voltage and current signals in a 1769 Compact I/O backplane. Each channel supports voltage ranges of -10 to +10 V, 0–10 V, 0–5 V, and 1–5 V, and current ranges of 0–20 mA and 4–20 mA, with full-scale values of ±10.5 V and 0–21 mA (and for narrower voltage ranges 0–10.5 V, 0–5.25 V, and 0.5–5.25 V). The module uses a 16‑bit A/D converter with per-channel filtering and reports engineering units scaled for PID or monitoring tasks. It features 500 Vdc field-to-backplane isolation and 500 Vdc field-to-chassis-ground isolation, protecting the controller and wiring. Backplane current draw is up to 45 mA at 24 V and up to 150 mA at 5 V, with a maximum about 3 W dissipation. Operating temperature is 0 to 60°C with 5 to 95% non-condensing humidity, and the unit is compatible with CompactLogix 1769 and MicroLogix 1500 systems. Designed for practical sensing of voltage and current signals in industrial environments, the 1769-IF8 enables straightforward integration of eight sensors or transducers into a single module for fast, real-time data acquisition.
