Description
Product Description
The 1769-OF2 is a compact analog output module developed by Allen-Bradley for use within the CompactLogix platform. It delivers two single-ended analog output channels capable of generating both voltage and current signals, making it suitable for precise control of actuators, drives, and process equipment.
This module utilizes a delta-sigma conversion architecture to achieve stable signal generation with high resolution. Designed for integration into Compact I/O racks, it offers flexible mounting, fast update rates, and built-in protection features to ensure reliable field operation.
The 1769-OF2 supports multiple output ranges, allowing it to adapt to a wide variety of industrial control requirements without additional signal conditioning hardware.

FAQ
What types of signals can the 1769-OF2 output?
It supports both voltage (±10 V, 0–10 V, etc.) and current (0–20 mA, 4–20 mA) signals, configurable per channel.
Is the module isolated?
The module provides reinforced isolation between the backplane and output group, but the output channels themselves are not individually isolated.
How fast is the output update rate?
All channels are updated within a maximum of 2.5 ms, suitable for most real-time control tasks.
Can it be used with MicroLogix systems?
No, the 1769-OF2 is designed specifically for CompactLogix and compatible Compact I/O platforms.
