Product Overview
The Omron NB3Q-TW01B-V1 is the 3.5-inch wide-screen TFT colour HMI in the NB3Q family. It is manufactured by Omron Corporation. Hengyixin Automation ships this HMI panel from Xiamen with the NB-Designer project file on a USB drive included.
The 320 x 240 QVGA panel shows 65,536 colours and the 4-wire resistive touch supports the same gestures the larger NB5 / NB7 / NB10 panels do. The NB3Q-TW01B-V1 is the right pick when the machine has fewer than 30 operator actions per screen - a small status / setpoint panel, a recipe selector, or a fault log view.
For larger screens (5.7 / 7 / 10.4 inch), move up the NB line without changing programming software. Key specs: Model NB3Q-TW01B-V1; Display 3.5-inch TFT colour LCD, 320 x 240 QVGA; Colours 65,536 (16-bit colour); Backlight LED (white / pink); Touch Panel 4-wire analog resistive; Supply Voltage 24 VDC +/- 15%, 5 W max; Communication Ports USB slave + RS-232C + RS-422A / RS-485; Supported Protocols Host Link (SYSMAC WAY), FINS, NT Link 1:1 + 1:N, Modbus RTU.

Best-Fit Applications
- Fault log viewer that pops a red banner when a CP1L-M fault bit sets.
- Spare replacement for an NS5-MQ00B-V2 panel when the cabinet cutout is too small for a 5.7-inch screen.
- Compact operator panel for a CP1L / CP2E-controlled machine where only a few setpoints and status bits are shown.
Buying Checklist
- Choose NB3Q-TW01B-V1 when 3.5 inches is enough and the budget is tight.
- Choose NB5Q-TW01B-V1 (5.7-inch) for a more readable panel on the same NB-Designer software.
- Choose NB7W-TW01B-V1 (7-inch) when the cabinet has the cutout space and you want larger fonts.

FAQ for NB3Q-TW01B-V1
What is the difference between NB3Q-TW00B and NB3Q-TW01B?
Same 3.5-inch screen, same resolution, same ports. TW00B is the grey-bezel variant; TW01B is the black-bezel variant. The V1 suffix marks the wide-screen QVGA panel; the original NB3Q-TW01B was the standard 3.5-inch screen without wide-screen aspect. The trailing SLN-VD variants add a status contact on the input side for systems needing input-state feedback to the controller.
What programming software does NB3Q-TW01B-V1 use?
NB-Designer Ver. 1.0X or later, the same tool used by the NB5Q / NB7W / NB10W panels. Projects are forward-compatible across the NB-series, so a panel can be swapped for a larger screen without rewriting the project from scratch. Older NB-Designer versions on a CX-One 3.x disc do not include the NB3Q device driver; upgrade before commissioning.
Can the NB3Q-TW01B-V1 connect to a non-Omron PLC?
Yes - the panel supports Modbus RTU master and slave on the RS-232C / RS-422A / RS-485 ports, plus Host Link (SYSMAC WAY) and FINS for Omron CPUs. For Modbus TCP / EtherNet/IP, step up to the NB5Q / NB7W with the Ethernet option board.
What is the maximum number of screens on the NB3Q-TW01B-V1?
Up to a few thousand screens depending on size, with tag counts driven by the project size rather than a hard limit. For very large projects (10k+ tags, large logging), step up to the NB10W or NS-series with a CF card slot.
