CHAPTER 3 – CONTROL SYSTEM 56
IOEC module configuration
Each IOEC module is configured with both analog
and digital inputs and outputs as shown in
Table 3-1
.
24 V internal voltage supply
One isolated DC/DC converter supplies an over-
load protected voltage of 24 V (DC) to operate dig-
ital inputs from passive contacts. The output is
protected by a PTC-resistor against short-circuit
and external applied overvoltages.
