Allen-Bradley 1769-IF4I 4-Point Analog Input Isolated Module – CompactLogix 1769 Series
When a critical analog input module fails on the production floor, the consequences are immediate and severe: process variables go blind, PID loops lose their feedback, and automated safety interlocks can no longer respond to real-world conditions. Conveyor lines halt, batch processes abort mid-cycle, and every minute of unplanned downtime translates directly into lost revenue and potential safety incidents. The Allen-Bradley 1769-IF4I is the precision component that stands between your control system and that scenario — delivering isolated, high-accuracy analog signal acquisition that your CompactLogix system depends on to maintain continuous, reliable operation.
Within the CompactLogix 1769 Series ecosystem, the 1769-IF4I occupies a specialized position as a fully isolated analog input module, supporting both current (mA) and voltage (V) signal types across four independent channels. Unlike non-isolated counterparts, its channel-to-channel and channel-to-backplane isolation architecture eliminates ground loop interference — a critical requirement in industrial environments with long cable runs, variable grounding conditions, or high-noise machinery. Globally, the 1769 Series is one of the most widely deployed compact PLC platforms in discrete and process manufacturing, making the 1769-IF4I a high-demand spare part and system expansion component across industries from automotive to oil & gas.

Frequently Asked Questions
Q: What is the difference between the 1769-IF4I and the 1769-IF8?
A: The 1769-IF4I provides 4 fully isolated analog input channels (channel-to-channel and channel-to-backplane isolation), making it ideal for applications with ground loop concerns or mixed signal sources. The 1769-IF8 offers 8 channels but without full channel isolation, suited for applications where all sensors share a common ground reference.
Q: Is the 1769-IF4I compatible with Studio 5000 Logix Designer?
A: Yes. The 1769-IF4I is natively supported in Studio 5000 Logix Designer (v21 and later) and RSLogix 5000. The module add-on profile (AOP) is available from Rockwell Automation’s Product Compatibility and Download Center (PCDC).
Q: Can the 1769-IF4I accept thermocouple signals directly?
A: No. The 1769-IF4I accepts standard analog current (mA) and voltage (V) signals. For direct thermocouple input, the 1769-IT6 module is the appropriate choice. Thermocouple signals can be connected to the 1769-IF4I via a signal transmitter/conditioner that converts to 4–20 mA or 0–10 V.
Q: Do you provide a Certificate of Conformance (CoC) with the 1769-IF4I?
A: Yes, upon request. Please specify your documentation requirements when submitting your inquiry and we will include the relevant certificates with your shipment.
Q: What is the lead time for the Allen-Bradley 1769-IF4I?
A: Lead time depends on current stock levels. In-stock units typically ship within 2–3 business days. For larger quantities or specific firmware revisions, please contact us for a confirmed lead time.
