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.
