With its compact design, the controller has two gigabit network connections, four USB interfaces, a DisplayPort and several serial interfaces. Wireless modules for 4G, 5G, Wi-Fi 5 and Wi-Fi 6 can be used via M.2 sockets, which enable real-time data transmission for mobile and gateway applications. The POC-40 shows its strengths above all in situations where space is at a premium when it comes to decentralized automation and data communication tasks. With its small dimensions of 52 x 89 x 112 mm (L x W x H) - this roughly corresponds to the size of a 2.5-inch SSD drive - the POC-40 embedded controller series is suitable for Installation in tight spaces. The POC-40 was developed primarily as a mobile gateway with a view to applications such as production data acquisition and edge computing in harsh environments.
