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.

Installation Guidelines

Mount the programmable terminal directly onto a flat panel of thickness between 1.6 mm and 4.8 mm.
Ensure an ambient operating temperature clearance of at least 50 mm around the back of the module to allow for adequate natural ventilation.
Tighten the four included mounting brackets evenly with a maximum torque of 0.5 to 0.6 N-m to maintain IP65-rated front face sealing.
Connect the Functional Ground (FG) terminal directly to a dedicated ground point of 100 ohms or less using minimum 2 mm sq. wire.
Keep communication lines and signal cables routed away from high-voltage AC power lines to avoid electromagnetic interference.
