The Advantech UNO-3283G and UNO-3285G models have SSD/HDD bays with RAID 0/1 support, which can be replaced during operation. The hard disk bays are accessible from the front and secured by a captive screw. They can be easily replaced in the event of failures or upgrades. The new UNO models are particularly suitable for factory and machine automation requirements. To ensure the best flexibility of the many I/O interfaces, the new models support iDoor technology. This offers users a range of additional modular I/O interfaces such as industrial fieldbuses and wireless connections. An L-shaped removable cover simplifies maintenance work on the UNO-3285G and facilitates access to the UNO interior. The L-shaped cover is equipped with captive screws to prevent loose screws from being lost during operation or when removing the cover. The design also makes the PCI/PCIe sockets, iDoor module, CFast slot and RTC battery easily accessible to users during installation and maintenance. A 6th generation Intel Core i7 processor is integrated in the UNO-3285G. The design supports power redundancy and operating temperatures from -20 to around 60°C.
