NB-IoT Product
GRP-540M-NB is an NB-IoT gateway that bridges an Ethernet network and three serial ports to a cellular NB-IoT link. It suits M2M designs that need to pass remote I/O or Modbus data to a central site without a fixed wired connection, and it adds GPS positioning with 32-channel All-In-View tracking.Supporting Modbus RTU and Modbus TCP as well as MQTT, the gateway can connect to an NB-DA Server or an MQTT Broker. From the remote control centre, the devices attached to the GRP-540M-NB can then be monitored and controlled. A micro SD card slot and a real-time clock support local storage and time-stamping.The metal casing is rated for an operating range of -25 ~ +75 °C and is designed for harsh industrial environments. It mounts on DIN-rail or by screws. The source lists this ordering code as available for Asia only, so confirm availability before ordering for European projects.ApplicationsNB-IoT gateway for M2M applicationsRemote I/O and Modbus data collection over NB-IoTData collection and remote control with NB-DA ServerData collection and remote control with MQTT Broker
