Allen Bradley 1769-OF4VI CompactLogix Compact Isolated Analog Output Module

Product Introduction

The Allen Bradley 1769-OF4VI CompactLogix Compact Isolated Analog Output Module is a high-performance isolated analog output module designed for use with the CompactLogix 1769 I/O platform. This module provides precise analog outputs with electrical isolation between channels and from the system backplane, ensuring safe and reliable control of industrial devices in environments where signal separation is critical.

The 1769-OF4VI module supports four independent output channels, allowing control of multiple analog devices simultaneously. Its isolated design protects both the module and connected field devices from electrical interference, ground loops, and potential voltage mismatches. This makes it particularly suitable for industrial automation systems requiring safe and reliable signal transmission for process control applications.

The module is capable of driving standard voltage and current analog signals to control actuators, valves, and other field equipment. Compact and lightweight, it integrates seamlessly into CompactLogix control architectures, providing flexible and scalable analog control capabilities.

Designed for industrial environments, the 1769-OF4VI ensures accurate and stable analog outputs even in challenging conditions, supporting precise machine operation, process automation, and remote device control.
