Omron NT31-ST123-V3
Original price was: $763.00.$477.00Current price is: $477.00.
The Omron NT31-ST123-V3 is a high-performance, mid-sized Human Machine Interface (HMI) from Omron’s classic NT series. The “V3” designation indicates it is the third and most advanced version of this model, offering expanded memory and improved communication features compared to the original V1 or V2 units.
1. Display and Visuals
-
Screen Type: STN Color LCD.
-
Screen Size: 5.7-inch diagonal.
-
Resolution: $320 \times 240$ pixels (QVGA).
-
Touch Panel: Matrix resistive touch, allowing for tactile on-screen buttons and data entry.
-
Backlight: Replaceable cold cathode fluorescent lamp (CFL), with a service life of approximately 50,000 hours.
2. Connectivity and Ports
One of the NT31’s strengths is its flexibility in connecting to various industrial devices:
-
Serial Port A: 9-pin D-sub (RS-232C only). Typically used for programming or connecting to a PLC.
-
Serial Port B: 25-pin D-sub. This is a multi-purpose port that can be configured for RS-232C, RS-422A, or RS-485.
-
Printer Port: A dedicated parallel port for connecting a printer to log data or print alarm reports.
3. Key Features
-
NT Link: A proprietary Omron high-speed communication protocol that allows the HMI to share data with Omron PLCs (CS/CJ/C200H series) with minimal lag.
-
Large Memory: The V3 model features 1 MB of screen data memory, allowing for hundreds of screens, complex graphics, and large alarm histories.
-
Device Compatibility: While built for Omron, it includes drivers for other major PLC brands like Mitsubishi, Allen-Bradley, and Siemens.
-
Recipe & Alarm Management: Built-in tools to handle machine “recipes” (settings) and detailed time-stamped alarm logging.
4. Technical Specifications
| Feature | Details |
| Model | NT31-ST123-V3 (The “B” version is Black, “V3” is the version) |
| Input Voltage | 24V DC |
| Current Consumption | Max 15W |
| Battery Type | 3V Lithium Battery (Reference: CJ1W-BAT01) |
| Protection | Equivalent to IP65 (Front panel) |
| Software | NT-Series Support Tool or CX-Designer (part of CX-One) |
5. Maintenance Note (V3 Specifics)
The V3 model is highly sought after as a spare part because it can run projects created for the older V1 and V2 models without modification.
-
Battery Alert: If the “Battery Low” indicator appears, you must replace the lithium battery quickly to avoid losing the internal memory data (recipes and history).
-
Backlight: If the screen becomes dim or flickering, the backlight can usually be replaced without changing the entire HMI.
Would you like me to find the “Serial Cable Pinout” to connect this NT31 to an Omron CP1H or CJ2M PLC?
