Powered by the latest generation of In® Celeron® processor J3455 (formerly codenamed "Apollo Lake"), NISE 51 series positions at the inligent IoT gateway for factory automation and for smart city applications. DDR3L SODIMM memory socket, the NISE 51 series support operating temperature from -5 up to 55 degree C with 12V/24V DC input with +/-10% range. The NISE 51 series have strong connectivity - Ethernet-based LAN port and traditional RS485, mainly for Modbus TCP or Modbus RTU communication. For wireless connectivity, there are 1 x mini-PCIe sockets and 2 x M.2 slots which can support optional wireless modules for IoT applications, for example, Wi-Fi, Bluetooth, 3.5G and 4G LTE module as well as storage module. NISE 51 is definiy the best choice for M2M inligent system as an inligent IoT gateway.
