5.1.4.  Inputs/ Outputs (MB-IO modules) 

 
It is possible to connect MB-IO modules on the MB-RS. 

 

 
MB-IO modules are fitted with 8 optocoupled inputs/outputs.  
 
The 8 outputs are similar to the « open collector PNP » type. They can be used with 
an  external  power  supply  12  to  30  VDC  maximum.  The  maximal  output  current 
drained by each output is 50mA 
 
The 8 inputs represent a 2.2kOhms load connected to the 0 volt. 
 
The inputs and outputs are isolated by optocoupler.
