Overview

The Allen-Bradley 1769-OF8C is a Compact I/O analog output module designed for use with 1769 CompactLogix, 1768 CompactLogix, and MicroLogix 1500 controllers. It is typically used for driving final control elements (FCEs) in closed-loop control systems, as well as for sending analog signals to measurement or receiving devices.

This module features eight (8) single-ended current output channels, configurable for 0–20 mA or 4–20 mA ranges. It incorporates a 16-bit Digital-to-Analog Converter (DAC) with effective resolutions of 0.323 µA/bit for both ranges. The 1769-OF8C ensures fast and reliable signal response with a maximum conversion rate of 5 ms and a step response time of under 2.9 ms to 63% of the final value.

Designed for industrial automation, the 1769-OF8C provides robust diagnostics including over-/under-range detection, broken wire indication, and load resistance monitoring, ensuring accuracy and reliability in critical applications.
