NT30-ST131-E belongs to Omron classic NT30 programmable terminal family. It adopts a 5.5-inch monochrome STN LCD screen with 320×240 QVGA resolution and analog resistive touch screen. Power supply DC24V, rated power consumption 15W. It is fitted with two serial interfaces: RS232C for program download and PC connection, RS422A for PLC communication.

This HMI supports NT Link and Host Link protocols to communicate with Omron C series and CJ series PLCs. Project configuration and screen download are completed by NT Support Tool software. It supports real-time data display, numerical setting, alarm message display, bar graph, touch switch and recipe storage functions. Front panel protection grade IP65 for cabinet flush mounting, rear housing IP20. LED indicators display power and communication status for fast field troubleshooting. Operating temperature range 0~50℃.

NT30-ST131-E is discontinued legacy Omron HMI spare part. Many old automation machines still run NT30 touch panel systems. When the original panel fails, replacing it with identical NT30-ST131-E can reuse existing panel cutout, wiring and original HMI project without redevelopment. Technicians install the touch panel, download screen program and verify PLC serial communication, so the local machine operation and monitoring system resumes operation and reduces downtime.

Before shipment, every NT30-ST131-E undergoes comprehensive functional inspection including power-on self-test, touch calibration, LCD display inspection, RS232C/RS422A communication verification and memory read-write test. All products come with 12-month warranty. Our automation technical team provides remote support for project backup, screen download, wiring guidance and communication fault diagnosis. Fast global shipping available for urgent maintenance orders.

For automation maintenance engineers and system integrators, NT30-ST131-E is reliable spare monochrome touch operator panel for legacy Omron NT series control systems. It restores local machine operation and process data monitoring functions, extends service life of automation assets and avoids high-cost whole control system renovation.
