Power supply DC24V, max power consumption 15W. Communication ports include RS232C and RS422A, support NT Link and Host Link protocol, mainly communicate with Omron old generation PLC series like CPM, CQM1, C200H. Widely applied in old packaging machinery, textile equipment and small production lines.

This HMI can realize real-time equipment status display, alarm message popup, parameter setting, touch button operation, recipe data storage. Project editing and download use dedicated NT Support Tool software. It supports screen switching, bit lamp display, numeric input, alarm logging function. Front panel is IP65 dust and water resistant for cabinet panel mounting, rear IP20. LED indicators show power and communication status for quick troubleshooting.

Full protection includes reverse polarity protection, overvoltage protection, internal circuit overheat protection. Operating temperature range 0~50℃, humidity 35~85% non-condensing. Overall dimension 195×142×55.6mm.

NT30C-ST141-E is discontinued legacy Omron HMI spare part. Many old automation machines still run NT30C touch panel. When the original unit fails, replacing it with identical NT30C-ST141-E can reuse existing panel cutout, communication cable and original NT project file without redevelopment. Technicians install the touch panel, download screen program and verify PLC communication, so the machine HMI operation system resumes operation and reduces downtime.

Before shipment, every NT30C-ST141-E undergoes comprehensive functional inspection including power-on self-test, touch calibration, display test, RS232/RS422 communication test 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, NT30C-ST141-E is reliable spare color touch terminal for legacy Omron NT series HMI systems. It restores machine local operation and status monitoring functions, extends service life of automation assets and avoids high-cost whole control system renovation.
