Introduction

RTU-540P-NB is is an intelligent Active LTE NB-IoT Remote Terminal Unit with GPS. Within the high performance 32 bit CPU, RTU-540P-NB is suit for the hard industrial environment. When connecting with NB-DA Server or MQTT Broker, the user can also control the devices which connected to RTU-540P-NB from the remote control center. It features LTE NB-IoT module, 6 digital inputs, 2 digital outputs, 1 analog input, 1 RS-232, 1 RS-485 and SD interface. It can be used in M2M application fields to transfer the local I/O, GPS and Modbus device's data via LTE NB-IoT by the defined period or DI/AI triggers. The local I/O and GPS data can also be stored in the SD card to become a remote data logger. It also supports Li-ion battery as another power source when the main power is failed temporarily. Therefore, RTU-540P-NB is an ideal solution for environmental monitoring, remote device management and vehicle monitoring system for M2M applications.
