Engineering Advantages
Versatile AC/DC Load Switching
The 2085-OW16 offers exceptional flexibility by supporting a broad operating voltage range, including 24V DC, 125V DC, 120V AC, and 240V AC. This allows automation specialists to control diverse field devices—from low-voltage DC solenoids to high-voltage AC motor contactors—using a single expansion module, significantly simplifying spare parts inventory and panel design.
High-Density Output Expansion
By providing 16 independent relay outputs in a compact footprint, this module maximizes the control capability of Micro850 and Micro870 systems. Each channel handles up to 2A, making it ideal for applications requiring numerous discrete control signals without the need for bulky external interface relays.
Electrical Isolation and Safety
Mechanical relay outputs provide inherent electrical isolation between the PLC logic side and the field wiring. This robust isolation protects the sensitive controller electronics from voltage spikes, electrical noise, and shorts on the load side, ensuring the longevity and stability of your automation system in electrically noisy industrial environments.

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.
