The power demand must be determined individually depending on the entry point
of the field supply. All loads through field devices and I/O modules must be taken
into account. The field supply also impacts the I/O modules because the input and
output drivers of some I/O modules require the voltage of the field supply.
System and field supply must be isolated!
The system supply and field supply must be isolated to ensure bus operation in the
event of short circuits on the actuator side.
Power supply units are available in the eShop.
You can find suitable power supply units, e. g. from the EPSITRON series, in the
eShop on www.wago.com.
