Introduction

The MPC-3120 12.1-inch panel computers with Intel Atom® x6211E dual-core or x6425E quad-core processor deliver a reliable, durable, and versatile platform for use in industrial environments. With two software selectable RS-232/422/485 serial ports and two Gigabit Ethernet ports, the MPC-3120 panel computers support a wide variety of serial interfaces as well as high-speed IT communications, all with native network redundancy. The MPC-3120 panel computers are designed for the -30 to 60°C temperature range, and come with a fanless, streamlined enclosure designed for highly efficient heat dissipation. This makes the computers reliable industrial platforms for harsh, hot, outdoor environments like oil and gas fields, or drilling platforms. The MPC-3120 also features a 400-nit or 1000-nit LCD panel offering a sunlight-readable, projected-capacitive, glove-friendly, multi-touch screen for excellent user experience in outdoor applications.
