Human Machine Interface, often known as HMI, refers to a dashboard or screen that controls machinery. The industry’s line operators, managers, and supervisors rely on HMIs to translate complex data into useful information.
Design and Construction: The Omron NS Series of Human-Machine Interfaces (HMIs) exemplifies design and build quality excellence. Characterized by a sleek and robust construction, these HMIs prioritize durability, making them well-suited for deployment in challenging industrial environments. Available in sizes from 4 to 15 inches, including handheld NSH Series models, all feature vibrant color TFT screens. Connectivity options include RS-232C, RS-422A, USB Slave and Master, Ethernet, and Controller Link. Safety features like emergency stop inputs with red and gray switches enhance operational control. High-resolution touchscreens and selected models with Ladder Monitor capability simplify operation and troubleshooting.
Omron’s NT Series, including models like NT20S and NT600S, offers cost-effective touchscreen terminals that enhance flexibility and operational efficiency. These HMIs support up to 3,999 screens, include Symbol Manager Previews, and allow editing of grouped parts. The compact design suits installations with space constraints. Features like dynamic labels, numeric/string display options, and field-replaceable backlights enhance customization and minimize downtime.
Network Connectivity: The NS Series supports serial NT Link communications (1:1 and 1:N), Controller Links, and Ethernet configurations, allowing flexible network architectures. Ethernet/IP support with tag-based access enables efficient data engineering and minimizes errors from address changes. RS-232C ports support direct connections to Temperature Controllers. The Face Plate Auto Builder feature simplifies screen creation for Loop Controllers.
The NT Series supports Host Link, NT Link 1:1, NT Link 1:N, and Memory Link protocols. It integrates with Ethernet/IP through Omron CJ2, NJ, and NX PLCs. Accessories such as communication cables, memory units, and protective covers improve system durability and usability.
Features and Performance Specifications: The NS Series (NS5, NS8, NS10, NS12, NS15) operates on 24 VDC with a power consumption up to 25W. They perform in temperatures from 0 to 50°C (up to 55°C for NS5), and storage from -20 to 60°C. With IP65F and NEMA4 compliance, these units resist environmental hazards. Battery life extends to five years, and a supercapacitor backs up SRAM/RTC during replacements. The NSH5 handheld units provide 320x240 resolution and matrix resistive membrane touch panels.
The NT Series, with models such as NT631C, NT31/NT31C, and NT20, offers rugged performance in ambient temperatures up to 50°C. These units handle vibration and shock effectively and conform to IP65F/NEMA4 for water and dust resistance. The NT631, with 50,000-hour life expectancy and adjustable contrast, is suited for long-term operation in harsh environments.
Application: The NS Series excels in machine control, process monitoring, and energy management. High-resolution displays and real-time visualization allow efficient monitoring in environments like chemical plants and power generation facilities.
The NT Series supports packaging, food and beverage, pharmaceutical, and building automation sectors. It ensures precision in packaging processes, maintains hygiene standards in food production, and monitors HVAC/security in buildings. The NT20 offers budget-conscious yet functional HMI solutions.
Conclusion: The NS Series offers a robust, high-resolution interface with advanced connectivity for demanding industrial applications. Features like Ethernet/IP, tag-based data access, and real-time temperature controller integration make it ideal for complex systems.
The NT Series focuses on cost-effective touchscreen solutions with versatile protocol support and compact design. It is suitable for broad industrial applications where budget efficiency is a priority.
Both series offer user-friendly screen design tools (CX-Designer for NS, NT Support Tool for NT), enhancing flexibility and programming efficiency. Their capabilities make them dependable solutions for various automation scenarios.
