Product Details
Product Description
The 1794-OE4 is a four-channel analog output module from Allen-Bradley’s FLEX I/O series, designed for precision voltage and current control in industrial automation systems. This compact module provides high-speed analog output capabilities for process applications requiring accurate analog signal generation.
Each of the four single-ended, non-isolated outputs uses pulse-width modulation (PWM) for smooth signal conversion, supporting both voltage and current modes. It integrates easily into various FLEX I/O terminal base units, offering flexibility for distributed control systems.

Tech & Buying Guide
Evolving SCADA System Architectures in Industrial Automation
A robust Supervisory Control and Data Acquisition (SCADA) system serves as the heartbeat of modern industrial operations. Understanding SCADA system architecture is vital for engineers designing efficient control systems. These architectures have evolved from isolated, monolithic structures to highly interconnected, networked ecosystems. Choosing the right design requires balancing data visibility, processing power, and long-term scalability requirements.
Choosing the Right Controller: PLC vs. Motion Controller in Industrial Automation
Selecting the optimal control architecture is a foundational decision in industrial automation. Engineers must frequently choose between a Programmable Logic Controller (PLC) and a dedicated Motion Controller. While both systems manage machinery, their underlying design philosophies differ significantly, impacting performance, scalability, and system integration.
Mastering PLC Power Supply Architectures and Operating Voltages
Selecting the correct operating voltage is a critical step in designing reliable industrial automation systems. Whether you are working with a compact PLC or a large-scale DCS, your power architecture dictates the system's longevity. In this guide, we explore the standard voltage ranges and power distribution strategies required to maintain stable factory automation operations.
