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.
FAQs

Tech & Buying Guide
Selecting the Right Cables for Industrial Automation: A Comprehensive Guide
Selecting the appropriate cabling infrastructure is critical for the success of any industrial automation project. Improper cable selection often leads to signal degradation, system instability, and costly downtime. As an automation engineer, I frequently see projects compromised by poor cabling choices in harsh industrial environments. This guide simplifies the complex landscape of cabling to help you make informed decisions for your PLC, DCS, and control systems.
Preventing Spurious Trips in Emergency Stop Systems: A Technical Guide
In industrial automation, the Emergency Stop (E-Stop) pushbutton is the ultimate safety line. However, relying on a single Normally-Closed (NC) contact can sometimes lead to unexpected spurious trips. As a control systems engineer, I have seen these nuisance trips halt entire production lines, causing significant downtime. Understanding why these components fail and how to implement robust architecture is essential for any reliable DCS or PLC-based safety system.
Sequencing Induction Motor Control with PLC Logic: Best Practices
In modern industrial automation, controlling a group of induction motors requires precision and safety. Uncontrolled simultaneous startup of multiple large motors often causes significant voltage dips, potentially triggering protective trips. Therefore, implementing a sequential startup and shutdown strategy is essential. This approach minimizes inrush current and ensures the system operates within established power constraints. A robust PLC program serves as the ideal engine for orchestrating these sequences.
