Configured for human-machine interface operator input and real-time process visualization in automated control networks, the Omron NB3Q-TW01B (NB3Q Programmable Terminal) provides direct physical/electrical execution.

Terminal Variant Configuration

• NB: Industrial HMI programmable terminal series family.
• 3Q: 3.5-inch active TFT LCD panel display.
• T: Analog resistive touch screen overlay unit.
• W01: Dual serial communication port interface options (RS-232C / RS-422A / RS-485).
• B: Black enclosure bezel housing design.

Structural & Display Specifications

Controller Interface & Protocol Execution

The programmable terminal communicates across serial fieldbus links to synchronize screen data blocks with host PLC controllers. High-speed serial arbitration maintains determinism during multi-page graphics refreshes, alarm handling, and data logging updates. Built-in firmware flash compatibility allows online project download routines while supporting I/O density scaling across connected expansion racks.

Standard Package Contents

• 1 x Omron NB3Q-TW01B Programmable Terminal Unit
• 2 x Panel Mounting Brackets and Screws
• 1 x Power Supply Terminal Block Connector
• 1 x Rubber Gasket Seal (Pre-installed)

Panel Mounting & Field Wiring Rules

• Enclosure Cutout: Prepare a rectangular panel cutout according to specified panel dimensions and insert the terminal from the front face.
• Bracket Fastening: Hook the surface mounting brackets into the side panel slots and tighten the screws evenly to maintain an IP65 front-panel seal.
• Ground Connection: Attach a dedicated ground wire (AWG 14 minimum) directly to the functional earth terminal to prevent electrostatic discharge.
• Signal Isolation: Separate serial communication lines (RS-232C / RS-422A / RS-485) from AC power feeds and VFD motor cables to avoid noise corruption.

Diagnostic FAQ

• What actuation force range is required to register a touch command on the display?

  The analog resistive panel requires an operating force between 0.5 and 0.8 N to trigger touch points.

• What rated mechanical press cycle lifespan does the touch surface support?

  The touch screen matrix is rated for a minimum of 1,000,000 press operations under standard 25 deg C ambient conditions.

• Can the HMI panel be hot-swapped while communication cables remain active?

  Disconnecting communication ports during active data transfers may fault host controller communication loops; power must be cycled off prior to hardware removal.

• How is the panel seal maintained against dust and water ingress?

  Proper tightening of the mounting brackets presses the integrated rubber gasket flush against the panel cutout to preserve the front protection rating.

• What color depth does the TFT LCD screen support for graphical objects?

  The 3.5-inch active display renders graphics, trend graphs, and process status indicators using 65,536 colors at 320 x 240 pixel resolution.

• Is external DC power required to energize the terminal display unit?

  Yes, the unit operates off an external 24 VDC power source wired directly to the removable power supply terminal block connector.

• How are project files transferred to internal flash memory?

  Applications are compiled via NB-Designer software and downloaded through a dedicated USB slave port or serial communication channel.

• What wire gauge should be selected for the DC power supply connections?

  Use stranded copper wiring between AWG 22 and AWG 16 with crimped ferrules to ensure stable terminal block connections.
