NB3Q-TW01B

The NB3Q-TW01B is a compact 3.5-inch TFT color touchscreen programmable terminal from Omron’s NB Series, designed for industrial automation and human-machine interface applications. Built around a QVGA 320 x 240 pixel display with 65,536 colors and an LED backlight, it delivers clear, high-visibility readouts ideal for monitoring and controlling automated processes on the factory floor. Its integrated Ethernet and USB Host ports set it apart within the NB3Q line, allowing easy project updates, network data exchange, and USB memory stick support without additional hardware.NB3Q-TW01B

This unit is rated IP65 for front-panel protection, making it well-suited to demanding industrial environments where dust and moisture are a concern. Connectivity is broad and flexible, supporting RS-232C, RS-422A, and RS-485 serial protocols alongside 10/100Base-T Ethernet — enabling seamless communication with Omron PLCs as well as many third-party controllers. The 9-pin D-sub serial connector and RJ45 Ethernet port give integrators multiple pathways for host connection, while the USB 2.0 port streamlines program transfer and data logging.NB3Q-TW01B

This listing is for a used and fully tested unit, inspected to confirm operational integrity before shipping. Sourcing a pre-owned programmable terminal is a practical, cost-effective strategy for maintenance and repair scenarios where the original panel is discontinued or lead times are prohibitive. Each unit is verified to power up and function correctly, giving buyers confidence in a part that is no longer manufactured new.NB3Q-TW01B

Whether you are replacing a failed display in an existing machine line or building out a spare-parts inventory, this tested panel offers a direct drop-in solution. The free NB-Designer software remains available for download, and the terminal supports both online and offline simulation, extensive language options, and multi-level security — making commissioning straightforward even for teams working with legacy equipment.NB3Q-TW01B
