ADS-300 is an ultra low power, wireless 4G/NB-IOT RTU

Introduction

ADS-300 is an ultra low power, battery powered NBIoT, LTE-M end node. The ADS-300 supports SSL, is available for global deployment and can be used with any major Cloud IoT platform like Microsoft Azure IoT Hub, Amazon Web services, Mosquitto MQTT, etc. It incorporates two inputs, one digital with pulse counter capability and one analog, as well as multiple excitation options for powering transducers. The ADS-300 supports SDI12 and Modbus sensors. A D-size Lithium Thionyl battery provides autonomous operation for over 10 years.

SDI-12 Serial Bus

SDI-12 is an asynchronous, ASCII, serial communications protocol that was developed for intelligent sensor instruments that typically monitor environmental, structural engineering and precision agriculture data. The communication is achieved by digital communications. The addressing system allows data recorder to communicate with several microprocessor-based sensors over a single line. ADS-300 is compliant to the SDI-12 Standard Version 1.2 and supports extended commands for sensor configuration, in terminal mode. ADS-300 can collect data from several SDI-12 sensors for a total amount of 8 measurement channels.

RS-485, MODBUS

ADS-300 supports acquisition from sensors with RS-485 interface, using the popular MODBUS protocol (RTU & ASCII). Up to 8 measurement channels from several sensors are supported.

Transducer excitation

The unit provides multiple excitation options for measuring transducers.
