1769-IF4XOF2 Functional Description

The I/O Module 1769-IF4XOF2 Allen-Bradley is a compact analog I/O module with 4 inputs (configurable as single-ended or differential) and 2 outputs, supporting 0-10V DC and 0-20mA signals. It features 8-bit resolution and is compatible with MicroLogix 1500 and CompactLogix controllers. The Allen-Bradley 1769-IF4XOF2 Analog I/O Module does not provide loop power, requiring an external supply matching transmitter specs. Its differential inputs offer better noise immunity, while voltage outputs reference ANLG COM with a minimum 1kΩ load resistance. Current outputs source up to 300Ω load resistance, ensuring stable signal transmission.

The 1769-IF4XOF2 Analog I/O Module Allen-Bradley uses successive approximation ADC for inputs, converting signals to 8-bit raw data for CPU processing. Input ranges extend slightly beyond nominal (0-10.5V DC, 0-21mA) for tolerance. With ±0.7% voltage accuracy and ±0.6% current accuracy, it suits applications where high precision isn’t critical. Thermal drift is minimal (±0.006%/°C), and 60dB common-mode rejection reduces interference. Outputs deliver 0-10.5V DC or 0-21mA via resistor-string DAC, responding within 0.3ms (resistive load) or 3ms (capacitive load).

Designed for cost-effective integration, the ROCKWELL 1769 Compact I/O Modules supports up to 8 modules per power supply in CompactLogix systems. Its 30V AC/DC operational rating and CE/c-UL certifications ensure industrial reliability. The 290-gram module measures 118x87x35mm, featuring an LED status indicator. While its 8-bit resolution limits high-accuracy uses, it excels in basic process monitoring, such as temperature or pressure sensing, where speed and simplicity are prioritized over extreme precision.

The Compact I/O analog combination module  Allen-Bradley 1769-IF4XOF2 balances performance and affordability, ideal for low-criticality automation tasks. Key specs include ±0.4% non-linearity, ±0.5% output accuracy, and 10mA max current load. Voltage outputs require >1kΩ loads, while current outputs tolerate ≤300Ω. With robust noise immunity and compact design, this module streamlines analog signal handling in Rockwell Automation environments, ensuring reliable operation in diverse industrial conditions.
