The SeaPAC R9-8.4 from SeaLevel System leverages a reduced instruction set computer (RISC)-based embedded computer with an 8.4-in. thin-film transistor (TFT) LCD to create a wide-temperature, ruggedized, flat panel computer. It is powered by a 400 MHz ARM9 microprocessor and is available with 128 MB RAM and 256 MB flash memory. Local or remote I/O expansion is available through a variety of configurations including optically isolated inputs, Reed and Form C relay outputs, TTL interfaces, A/D, and D/A. The computer features one 10/100 BaseT Ethernet port, two USB 2.0 ports, one USB device port, eight open collector digital outputs, two isolated RS-485 serial ports, one dedicated RS-485 serial port via a RJ45 connector, and one RS-232 serial port. The resistive touchscreen is suitable for a wide range of industrial environments and applications, with an operating temperature range of -30°C to 70°C.
