Allen-Bradley 1769-IF4I CompactLogix 4-Channel Isolated Analog Input Module
Allen-Bradley 1769-IF4I is a CompactLogix 1769 Compact I/O isolated analog input module with 4 individually isolated differential or single-ended channels. It accepts voltage signals (±10 V, 0…10 V, 0…5 V, 1…5 V) and current signals (0…20 mA, 4…20 mA) with 16-bit resolution (unipolar) and a Delta Sigma converter — ideal for transmitters and sensors that need channel-to-channel isolation.
Overview
The 1769-IF4I belongs to the Allen-Bradley CompactLogix 1769 Compact I/O family. It connects directly to the Compact I/O bus beside the controller or an expansion power supply — no connection cables needed — and shares the same DIN-rail footprint and Studio 5000 (RSLogix 5000) engineering environment as the rest of the 1769 line.
Key Features
- 4 individually isolated inputs (differential or single-ended wiring)
- Voltage ranges ±10 V, 0…10 V, 0…5 V, 1…5 V; current ranges 0…20 mA, 4…20 mA
- 16-bit resolution (unipolar), 15 bits plus sign (bipolar); Delta Sigma converter
- Accuracy: voltage ±0.2% full scale, current ±0.35% full scale at 25 °C
- Channel-to-channel and channel-to-rack isolation: 500 V AC / 710 V DC for 1 minute
- Bus current draw 140 mA @ 5 V DC; 110 mA @ 24 V DC; heat dissipation 3.0 W max
- Individually configurable channels, auto-calibration, selectable filters and broken-sensor response
- Replacement terminal block 1769-RTBN18; 22…14 AWG wiring

Applications
The 1769-IF4I is used wherever analog transmitters, sensors, and signal converters must be isolated channel-to-channel — flow, pressure, temperature, and level loops in packaging, process skids, water treatment, and OEM machinery. Each channel is individually configurable with selectable filters and broken-sensor response.
