RD32 Stand-alone Data Logger

Overview

This data logger has been designed for data acquisition and transmission from sites without AC power supply. Its low power consumption makes it an ideal solution for telemetry applications.

Sensors

The RD32 is provided with 8 analog and 14 digital inputs, with scalable and programmable ranges and 2 serial ports (RS232, RS485). They make it suitable for the most part of the sensors on the market, even the intelligent ones.

Storage

Storing data internally (512KB RAM) is reliable because the RD32 is provided with an internal battery with high autonomy. In case of larger amount of data, storing is possible on an external compact flash (up to 512MB).

Low Power

The RD32 perfectly fits field installations in limited energy conditions. Electronics and software are specifically low power oriented, in order to maximize the autonomy.

Front-end-functionality

The RD32 has two RS232/485 ports to carry out a user-friendly management through a command console. From this terminal we can perform: parameters configuration, operation monitoring, alarms management and visualization of real time data and stored in both internal and external memories.

Time Synchronization

The RD32 is able to automatically synchronize the time, if connected with a GPS through any serial port.
