Allen-Bradley 1769-IF4 Description
CompactLogix 4-Channel Analog Input Module (Voltage/Current, 14-Bit)
Allen-Bradley 1769-IF4 is a CompactLogix 4-channel analog input module from the Allen-Bradley 1769 Compact I/O family. This high-resolution Delta-Sigma input module reads four voltage or current signals in single-ended or differential mode and is commonly used in machine-level control, process skids, water/wastewater panels, and any 1769 CompactLogix system that needs reliable analog measurement from the field.
Reliable Industrial Performance
The 1769-IF4 analog input module delivers accurate, low-noise field measurements in demanding industrial environments. A Delta-Sigma converter provides 14-bit resolution in unipolar mode and 14 bits plus sign in bipolar mode, with 120 mA @ 5 V DC and 60 mA @ 24 V DC backplane current draw. Field signal conditioning on each channel supports ±10 V, 0–10 V, 0–5 V, 1–5 V, 0–20 mA and 4–20 mA inputs, with a typical input impedance of 220 kΩ on voltage terminals and 250 Ω on current terminals. Rated for 30 V AC / 30 V DC working voltage and 500 V AC / 710 V DC channel-to-backplane isolation, the module integrates cleanly into 1769 CompactLogix and MicroLogix 1500 systems without extra signal conditioning hardware.
Key Features
- 4 channels of analog input – single-ended or differential wiring on the same module
- 14-bit resolution (unipolar) / 14-bit + sign (bipolar) via a Delta-Sigma converter
- Multi-range inputs – ±10 V, 0–10 V, 0–5 V, 1–5 V, 0–20 mA, 4–20 mA
- 120 mA @ 5 V DC and 60 mA @ 24 V DC backplane current draw
- 2.63 W max heat dissipation – low thermal load in the cabinet
- 500 V AC / 710 V DC isolation between field and backplane
- Compact 1-slot width – frees panel space for additional I/O
- 1769-RTBN18 screw terminal block included for 22–14 AWG wiring
- Compatible with CompactLogix and MicroLogix 1500 controllers and 1769-PA2/PB2/PA4/PB4 power supplies

Why Choose the Allen-Bradley 1769-IF4
The 1769-IF4 is a go-to analog input module for CompactLogix systems that need to read 4–20 mA loops, 0–10 V signals, or bipolar ±10 V transducers (load cells, position sensors) without an extra signal conditioner. Its Delta-Sigma converter and 14-bit resolution provide clean readings for process control, while the 1769 form factor drops directly into any 1769 CompactLogix rack next to digital I/O, high-speed counters, or communication modules.
