POWER SUPPLY 

Supply voltage 

10 

– 40 Vdc or 19 – 28 Vac ( 50Hz - 60Hz) 

Power  
consumption

 

Min: 0.5W;  Max: 2W (to power 4 current loop) 

 

The  power  supply  transformer  necessary  to  supply  the  module  must  comply  with  EN60742 
(Isolated transformers and safety transformers requirements). To protect the power supply, it is 
recommended to install a fuse. 

 

Input connections 

It is possible to connect two types of sensors to the Z-4AI module: 

 

passive sensors

, indicated with “S” label (these sensors have to be supplied: by a module 

external voltage Vext or by the module internal voltage Vaux); 

 

active  sensors

,  indicated  with  “voltage  generator”  or  “current  generator”  label  (these 

sensors have already been supplied). 

In the following figure are shown five possible sensor connections.
