Power Supply Units
The WAGO I/O SYSTEM 750 XTR requires 24 VDC voltage (system supply) for
operation.
Recommendation
A stable power supply cannot always be assumed everywhere. Therefore, you
should use regulated power supplies to ensure the quality of the supply voltage
(see also table “WAGO power supply units”).
For brief voltage dips, a buffer (200 µF per 1 A load current) must be provided.
Buffer for system power supply!
The system power supply must be buffered to bridge power outages. As the
power demand depends on the respective node configuration, buffering is not
implemented internally.
To achieve power outages of 1 ms to 10 ms according to IEC61131-2, determine
the buffering appropriate for your node configuration and structure it as an
external circuit.
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.
