Product overview 
 
Embedded PC  53 
CX1100-0001 connections 
This power supply unit does not have an I/O interface. The power supply is therefore connected through the 5-pin 
open pluggable connector. The power supply unit supplies all further system components with a voltage of 24 V DC (-
15 %/+20%) via the PC104 bus. The dielectric strength of the power supply unit is 500 V
rms
. 
The integrated NOVRAM permits storage of process data that is safe against power failure.
