OMRON NB7W-TW01B 7-Inch Wide-Screen HMI
The OMRON NB7W-TW01B is a high-performance human-machine interface from the NB series, designed to provide intuitive visualization and control for industrial machinery and processes. With a 7-inch widescreen TFT LCD, it delivers clear graphical interfaces for monitoring, data entry, and alarm management.
Display and User Interface
The NB7W-TW01B features a 7-inch wide-format color display with 800 x 480 pixel resolution (WVGA). The screen offers 65,536 colors, providing vivid graphics and easy readability under various lighting conditions. The analog resistive touch panel supports both finger and gloved operation, with a resolution of 1024 x 1024 touch points. Adjustable backlight brightness (300 cd/m²) ensures visibility in dim to bright ambient light. The backlight lifetime is rated at 20,000 hours, reducing maintenance concerns.
User interface features include bitmap fonts, TrueType fonts, and support for image and video playback. The HMI includes built-in recipe memory, data logging, and trend graphs. Real-time clock with battery backup allows time-stamped events and scheduled operations.
Connectivity and Protocols
The NB7W-TW01B provides multiple communication ports: one RS-232C, one RS-422/485, and one Ethernet port (10/100Base-T). This allows simultaneous connection to up to four different PLCs or devices. It supports native Omron protocols (Host Link, FINS, EtherNet/IP) as well as third-party drivers for Siemens, Mitsubishi, Allen Bradley, Modbus, and other major PLC brands. USB host port is available for data transfer to a USB drive (logging, screen capture, backup) and USB device port for programming download.
Configuration is accomplished using NB-Designer software, free from Omron. The software features over 1000 built-in vector and bitmap symbols, macro language, alarm handling, and multilingual text support (up to 32 languages with on-screen switching). The HMI supports up to 128 MB of project memory and 32 MB of data log storage.
Performance and Environmental Ratings
The ARM9 processor ensures fast screen switching and data processing. The NB7W-TW01B operates from 0 to 50°C and withstands humidity 10-90% non-condensing. Its front panel meets IP65/NEMA 4X rating, protecting against water jets and dust, making it suitable for washdown areas and harsh industrial environments. Power supply is 24V DC (typical 7W consumption).
Certified with CE, UL, and cUL, the unit is ready for global use. Dimensions: 196 x 128 x 48 mm (WxHxD) with a cutout of 185 x 115 mm for panel mounting. Weight is approximately 0.65 kg.
Applications and Benefits
The OMRON NB7W-TW01B is ideal for packaging machines, conveying systems, textile machinery, plastic molding, small production lines, and HVAC controls. It enhances operator efficiency with clear alarms, recipe management, and real-time trend display. The Ethernet port enables remote monitoring via web server (optional) and easy integration with SCADA systems. The NB series HMI offers cost-effective visualization without sacrificing essential features, making it a popular choice for machine builders.
Firmware updates and project transfer are simple using USB or Ethernet. The NB7W-TW01B provides a reliable, user-friendly interface that reduces operator errors and increases productivity.
