System supply
General information
The BL67 station is either powered
separately via the PROFIBUS-DP,
CANopen or Ethernet gateway or directly
via the DeviceNet™ or CANopen cable on
the DeviceNet™ gateway.
Power feeding modules can be installed
at any point within the BL67 station. They
provide an isolated field voltage to all
System supply via the
module bus
The number of BL67 modules, which can
be powered via the internal module bus,
depends on the nominal current rating I
MB
of the individual modules on the module
bus. The total current consumption of the
installed BL67 modules may not exceed
1.5 A.
When using the software I/O-ASSISTANT
the menu item <Station - Verify> will
automatically generate an error indication if
the system supply via the module bus is
not reliably ensured.
modules mounted to their right. Power
feeding modules can also be used to
create various potential groups.
