Product Description

Description

Engineered for industrial human-machine interface applications, the Omron NT31-ST122B-EV2 serves as a rugged programmable terminal featuring a highly legible STN monochrome display. This HMI module supports versatile host communication protocols, facilitating real-time monitoring and control on automated factory floors. By integrating multiple serial interfaces, including dedicated RS-232C and selectable RS-422A/485 ports, this device bridges the gap between operators and PLC-driven machinery. The compact 5.7-inch design delivers dependable visual feedback and resistive touch matrix input, tailored for space-constrained operator panels.

Features

  • 5.7-inch STN monochrome LCD display with blue mode visualization.
  • Matrix resistive touch panel with 128 touch switches (8 x 16 layout) for reliable tactile response.
  • Dual serial ports enabling flexible concurrent communication with host PLCs, temperature controllers, and barcode readers.
  • Built-in printer port conforming to Centronics standards for direct report logging.
  • 1 MB of internal flash memory to safeguard screen configuration and project data.
  • NEMA 4/IP65 rated front panel construction, providing resilient protection against ingress of oil, dust, and water spray.

Applications

  • Machine tool automation and diagnostic operator workstations.
  • Conveyor and material handling control consoles.
  • Packaging, labeling, and filling equipment interfaces.
  • Water treatment, HVAC, and auxiliary system status displays.
