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
Understanding Types of Noise in Electronic Circuits and Control Systems
Signal integrity directly determines measurement accuracy and loop stability across industrial automation environments. Electronic noise introduces unwanted stochastic interference into analog loops, sensor feedback lines, and digital fieldbus networks. Understanding how intrinsic electronic noise and external electromagnetic interference manifest allows control engineers to optimize signal conditioning and shield sensitive instrumentation effectively.
Why 24V DC Power Supplies Standardize Modern Industrial Automation
Industrial control cabinets worldwide rely on 24V DC as the universal power standard for field instrumentation, sensors, and controllers. Walk into any manufacturing plant, and you will find PLCs, human-machine interfaces (HMIs), and smart actuators running on extra-low voltage DC. Standardizing on 24V DC enhances operational safety, lowers cabinet footprint, and maintains steady control performance across factory networks.
Essential Motion Control Commands: A Practical Guide for Engineers
Automation engineers often rely on precise position and speed control to drive modern factory machinery. Modern industrial systems, such as Programmable Logic Controllers (PLCs) and Distributed Control Systems (DCS), depend heavily on standardized motion instructions. Mastering these commands ensures operational safety, protects mechanical components, and optimizes cycle times across production lines.
