duagon DC19 and DC20 rugged panel PCs for interactive rail applications
duagon’s DC19 and DC20 panel PCs have been designed for rugged railway applications and can be tailored for different train models. Both the 12.1″ DC20 and the 10.4″ DC19 house a robust, impact-resistant XGA TFT LCD display with LED backlight with an additional touch screen. Due to the high resolution and optimised usability of the displays, the panel PCs can be used for CCTV purposes.
Since the space in the driver cabin of a train is limited, the PCs have small, ultraflat mechanical design and configuration options. They come with a rugged housing with an IP65-compliant front, which supports a railway-compliant power supply of 24 to 110 VDC, its internal PSU complying with EN 50155 class S2. All electronic components are soldered to withstand shock and vibration, backed up by solid M12 connectors and protected by conformal coating. According to the standard, both panel PCs operate in environments from -25 to +70°C (+85°C for 10 min), which is achieved through fanless conduction-cooling technology.
The maintenance-free human–machine interfaces (HMIs) are powered by an Intel Atom processor from the E3900 series running at up to 1.6 GHz and equipped with up to 8 GB RAM with ECC and a 32 GB soldered eMMC. Standard interfaces include two Gigabit Ethernet, one CAN, one audio, two digital I/O and RS232/RS422/RS485, which are all available on M12 connectors at the back of the panel PC. Wireless communication functions such as 4G and GNSS and be controlled by two PCI Express Mini Card interfaces. Two micro-SIM card slots with dual-SIM functionality are accessible at the back of the panel.
