The MPC-3121-E4-SPK-CT-T is a 12.1 inch fanless industrial panel PC with a 1000-nit sunlight-readable display and integrated 2W speaker. It is designed for railway, transport, outdoor industrial and harsh-environment HMI applications that need a bright touchscreen, rugged connectivity and local audio output. Typical applications include driver cab displays, onboard control systems, operator terminals, monitoring stations, alarm panels and industrial equipment interfaces.
The system is powered by the Intel Atom x6425E quad-core processor and includes Intel UHD Graphics. It is supplied with 8GB DDR4 2400MHz memory and supports up to 32GB through one SODIMM slot. For storage and expansion, the panel PC includes one CFast slot, one M.2 M-Key 2242 socket and one mini PCIe slot, giving users options for operating system storage, application storage, data logging and additional embedded functions.
The display is a 12.1 inch 4:3 panel with 1024 x 768 resolution, 16.7 million colours, 1000:1 typical contrast ratio and wide 178 degree viewing angles. Its 1000cd/m brightness makes it particularly suitable for environments with strong ambient light or outdoor exposure. The projected capacitive touchscreen supports 4-point multi-touch and glove operation, helping ensure usability in cold, outdoor, transport and industrial environments.
The built-in 2W speaker provides local audio capability for alerts, prompts and operator feedback. Standard I/O includes two M12 push-pull Gigabit Ethernet ports, one RS-232/422/485 serial port, four digital inputs, two digital outputs, USB 2.0 and speaker or line-out audio. Ethernet ports include built-in 1.5 kV magnetic isolation, while the digital inputs and outputs include 3 kV optical isolation.
The MPC-3121-E4-SPK-CT-T supports 24V to 110V DC input and has a listed 51W power consumption. It operates from -40°C to 70°C without a fan or heater. Due to the integrated speaker, this model is rated IP66 at the front and IP40 at the rear. With EN 50155 compliance, shock and vibration standards, TPM 2.0, CE and FCC Class A approvals, IEC and UL safety standards, and support for Windows 10 IoT, Windows 11, Debian 13 and Ubuntu 24.04 drivers, it is a strong 12.1 inch panel PC option for bright-display applications requiring integrated audio.
