Power distribution system SVS09
Description
The SVS09 power distribution system with integral signalling module
optimises DC 24 V distribution at the machine-oriented field level
in automated process control, production plants and power plants.
Offering 10-plug-in sockets for electronic and thermal-magnetic circuit
breakers and an integrated alarm handling function for single and group
signalisation, the SVS09 distribution board can be cascaded on the
master-slave principle to meet specific requirements. This cascading
allows transducers, actuators, valves, distributed PLCs, intelligent
terminals etc. to be clustered into distinct function groups and to be
conveniently incorporated into the plant’s overall alarm monitoring
scheme. Particularly for applications with a great number of sensors/
actuators, the SVS09 offers possibilities for cost- and space-saving in
the design of control cabinets.

= 25 °C, U = DC 24 V)
Each load circuit that is interrupted by an overload or short circuit trip
always generates a single alarm. In addition, a group alarm for the entire
SVS09 cascade is induced which will be acknowledged by means of
a command element (momentary switch, relay, PLC) either locally in
the control cabinet or remotely in the control room. Acknowledging
the group alarm immediately reactivates the group signalling function
of the SVS09 cascade remobilising it for new incoming short-circuit or
overload messages.
