E-Log Data Logger

E-log has been explicitly designed for environmental applications: it is equipped with specific inputs for a wide range of sensors and calculations of derived quantities. E-Log stores the data from the connected sensors and supports different communcation protocols both in input and output. Robust and reliable, E-Log makes measurements possible even in the most severe environments, while the 16-bit A/D converter ensures accurate and reliable data in classic meteorological, hydrological and air quality applications and – more generally – in any environmental application.

Inputs for analog and digital sensors
Free terminal inputs

•N.8 analog diff erential inputs (N.16 single -ended)

• N.4 digital inputs (Pulse/Frequency)
To increase the number of inputs, two E-Log units can be jointed together
using a Master & Slave using a RS232 (ELO3305) or RS485 (ELO3305.1) connection.

Inputs for Serial sensors

The E-Log COM-2 port can be connected to sensors with different protocols:
• Modbus-RTU on RS232 or RS485 (with adapter external DEA504 for model ELO3305, directly for model ELO3305.1)
• GILL (Gill format, polar, continuous)
• BIRAL (SWS050 – SWS100, SWS200 –SWS250)
• LUFFT (UMB binary)
• BOSCHUNG
E-Log can also be connected via RS232 to EXP301 radio receiver to receive signals from LSI LASTEM’s radio sensors (EXP line).
