Description 

 

 

eDAS

 is a 16-bit, fully programmable data logger designed to offer a 

comprehensive  solution  to  structural  and  environmental  monitoring 
needs  wherever  signals  to  be  recorded  are  expected  to  be  slowly 

changing. 
 
The  system  core  is  represented  by  a  8-channel  module  that  digitizes 
and formats input signals in order to send them to and / or record them 

in the internal memory of the system.  
This  module  is  enclosed  in  a  robust,  IP65-rated  case,  fitted  with 

connectors and cable glands, that hosts a user-replaceable main battery 
and a backup battery as well.  
  
 

eDAS

 logger, that basically comes as a standard 8-channel unit, can 

be  used  as  a  remote  acquisition  system  and,  thanks  to  the  internal 

battery  and  low  consumption  features,  is  suitable  for  virtually  any 
installation place. 
 
Similarly, it can operate as a distributed multi-channel system made up 

of  as  many  as  255  units,  deployed  in  proximity  with  sensors,  inter-
connected via a RS422 / RS485 serial BUS. The BUS will also work as a 

means  to  feed  all  the  networked  units  from  an  additional  12/24  Vdc 
power supply consisting in a battery with relevant charger and, if any, a 

photovoltaic panel (

Powerbox

). 

Further,  it  is  possible  to  increase  the  number  of  channels  available  by 

implementing  a  number  of  multiplexers  in  order  to  get  standard 
versions of 16- or 32-channel data loggers.  

 
On request, larger customized systems are assembled in special cases   
according to the monitoring project needs.
