Display and Keypad Interface

The Schneider XBT PM027010 features a 2.5-inch monochrome LCD with 128 × 64 resolution. A green LED backlight improves visibility in dim control cabinets or machine enclosures. Sixteen tactile keys provide positive feedback for confident data entry. Eight programmable function keys give one-touch access to critical controls.

Communication Connectivity

One RS-232 port connects directly to a single PLC or programming PC. A separate RS-485 port supports Modbus RTU multi-drop networks on the factory floor. The panel acts as a Modbus master to poll data from multiple slaves. Consequently, you can monitor several devices from one operator panel.

Memory and Application Storage

This unit provides 1 MB of Flash memory for storing application screens and logic. An additional 256 KB of SRAM holds runtime variables and alarm messages. The total application size can reach up to 200 screens in typical projects. Therefore, this panel suits small to medium machine applications comfortably.

Installation and Mounting

Mount this panel into a standard panel cutout of 88 mm × 66 mm. The front panel meets IP65 rating when you properly seal the gasket. Four mounting clips secure the unit without requiring any special tools. For best results, avoid direct sunlight and heat sources above 50°C.

Programming and Configuration

You need Schneider Vijeo Designer Lite software to create applications for this panel. The software supports multi-language text, bitmaps, and alarm messages. You can download applications through either the RS-232 or RS-485 port. Therefore, no special programming cable is needed for this device.

Practical Applications

This keypad panel suits harsh environments where touchscreens are impractical. Gloved operators can use the tactile keys without any difficulty. The small footprint fits into tight spaces on existing machinery. Therefore, this unit works well for industrial ovens, washdown areas, and outdoor enclosures.

Why Choose This Panel

Operators prefer this keypad panel for reliable operation in dirty or wet environments. Touchscreens often fail when moisture or debris covers the surface. Consequently, manufacturers choose this unit for food processing, mining, and heavy industrial applications.
