The SeaPAC R9-8.4 from Sealevel Systems combines a RISC-based embedded computer with a bright LED-backlit thin-film-transistor LCD touchscreen to create a ruggedized, flat-panel computer intended for use in a variety of human-machine interface applications. The R9-8.4 operates in an extended temperature range – between -30 °C and +70 °C with no heaters or cooling fans required – making it suitable for harsh or hazardous environments. Driven by a 400-MHz ARM9 microprocessor, the touchscreen computer is available with 128 MB RAM and 256 MB of flash memory, with standard I/O including Ethernet, serial, USB, and digital interfaces. Local or remote I/O expansion is available using Sealevel SeaI/O modules, with the ability to choose a variety of I/O configurations including optically isolated inputs, Reed and Form C relay outputs, TTL interfaces, A/D, and D/A. The SeaPAC R9-8.4 connects to SeaI/O modules via the system’s RS-485 expansion port, with Modbus RTU handling the communications. The SeaPAC R9-8.4 flat-panel bezel also provides NEMA 4/IP65-compliant protection against particles and sprayed liquids.
The SeaPAC R9-8.4’s software package is equipped with the Sealevel Talos I/O Framework, which offers a high-level object-oriented .NET Compact Framework (CF) device interface. This interface provides an I/O point abstraction layer with built-in support for easily interfacing the system’s I/O. Linux support is also available.
