The X 55, comprised of an industrial-strength, premium-grade panel, is designed for 24/7 operation and includes thermal protection, internal temperature sensors with self-diagnostics and fan-based technology. The display is LED BLU, meaning that power consumption is decreased and that the display has a slimmer depth. It also features a built-in, standardized expansion slot — commonly known as an Open Pluggable Specification (OPS) slot — that allows for seamless integration with third-party components such as single board computers or media players. The display is integrated with an infra red technology that offers 12 touch points.
