Allen-Bradley 2085-OF4 Micro800 4-Channel Analog Output Module

Product Overview

The Allen-Bradley 2085-OF4 serves as a versatile 4-channel analog output expansion module designed specifically for the Micro800 PLC family. It enables precise process control by converting digital commands into standard analog signals, supporting both 0 to 20 mA current loops and -10 to +10 V DC voltage outputs. With a 12-bit resolution, this module delivers the accuracy required to drive variable frequency drives (VFDs), control valves, and other analog field devices seamlessly. We supply this item as a 100% Brand New, factory-sealed unit.

Technical Specifications

Engineering Advantages

Dual-Mode Voltage and Current Output
The 2085-OF4 offers exceptional flexibility by supporting both current (0 to 20 mA) and voltage (-10 to +10 V DC) signals on the same module. This dual capability allows engineers to interface with a wide variety of industrial equipment—from long-distance current-loop transmitters to voltage-controlled motor drives—without needing to stock multiple types of analog output modules.

High-Resolution Process Control
Featuring a 12-bit resolution, this module provides granular control over your analog processes. The high degree of precision ensures that actuators, heaters, and flow regulators respond accurately to the PLC's logic, minimizing process variation and improving overall product quality in demanding manufacturing applications.

Robust Industrial Environmental Tolerance
Engineered for the factory floor, the 2085-OF4 withstands harsh operating conditions. It resists mechanical stress with a vibration tolerance of up to 500 Hz and operates reliably in environments with up to 80% non-condensing humidity. The integrated LED indicators provide instant visual diagnostics, allowing maintenance teams to quickly verify channel status and troubleshoot wiring issues.
