Allen-Bradley 1769-OF8V CompactLogix 8-Channel Analog Voltage Output Module

Product Overview

The 1769-OF8V is a high-density analog output module designed for Allen-Bradley CompactLogix and MicroLogix 1500 controller platforms. This module provides 8 high-precision voltage output channels, supporting both unipolar (0 to 10V DC) and bipolar (±10V DC) ranges. It is an essential component for controlling industrial equipment such as variable frequency drives (VFDs), proportional valve positioners, and actuators that require a high-resolution command signal. The 1769-OF8V features integrated digital-to-analog converters (DACs) with individual channel configuration, ensuring reliable and deterministic control in electrically noisy industrial environments.
