ESC32 Datalogger / Data interface

Overview

This data logger has been designed for data acquisition and transmission of meteorological and environmental sensors. Its low power consumption makes it an ideal solution for telemetry applications. It is based on our RD32 datalogger, without display and housed in a weatherproof case with IP65, M12 connectors.

Sensors

The ESC32 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 ESC32 is provided with an internal battery with high autonomy.

Low Power

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

Management

The ESC32 has one RS485 port 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 stored and real time data. Access to information is also available using Modbus protocol, well suited for multiple equipment facilities.

Time synchronization

An external GPS connected to an RS232/485 port carries out Time synchronization.
