AERINOS ADS-210, End Node

Introduction

ADS-210 is a battery powered ProfiSens end node for low voltage, low power sensors. The unit is available for the 433 MHz licence free band. It incorporates one input, configurable as analog, or pulse counter input and multiple excitation options for powering measuring transducers. Dedicated digital interfaces support the SDI-12 and MODBUS communication protocols. A D-size Lithium Thionyl battery can provide autonomous operation for over 5 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-260 is compliant to the SDI-12 Standard Version 1.2 and supports extended commands for sensor configuration, in terminal mode. ADS-260 can collect data from several SDI-12 sensors for a total amount of 8 measurement channels.

RS-485, MODBUS

ADS-260 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.
