Moxa MC-1121-E2-T, Intel Atom E3826, 4GB DDR3L Industrial Fanless PC
Moxa MC-1121-E2-T is an industrial fanless PC designed for reliable computing in demanding industrial environments. It features an Intel Atom E3826 processor with 4GB DDR3L system memory and Intel HD Graphics. The fanless design helps support stable operation where low-maintenance industrial computing is required.
The system provides flexible storage and expansion through one CFast slot, one SD slot, and one mPCIe slot. It also includes one SODIMM DDR3/DDR3L memory slot and supports Windows 10 IoT Enterprise LTSC 2021 and Linux Debian 9 with kernel v4.9. These options allow the system to be used with different industrial software and system configurations.
For industrial connectivity, the MC-1121-E2-T provides four auto-sensing 10/100/1000 Mbps Ethernet ports, two software-selectable RS-232/422/485 serial ports, and two USB 2.0 ports. It also includes four digital inputs and four digital outputs for connecting industrial devices and control equipment.
The PC supports DisplayPort and VGA video output for connecting external displays. A mini SIM format is supported for the MC-1121/1122 models, while LED indicators provide system, storage, LAN, and serial status information. The built-in watchdog timer provides an automatic reboot trigger for improved system reliability.
With its metal housing, DIN-rail mounting, optional wall mounting, wide 11.4 to 36 VDC input range, and operating temperature of -40 to 70°C, the Moxa MC-1121-E2-T is suitable for industrial automation, machine control, monitoring, networking, and edge computing applications where compact and dependable fanless operation is required.
