Separation of supply
When used with the relevant base module, any electronic supply voltage module is suitable
to separate supplies and form supply groups.
To separate supplies, the supply (periphery supply and C-rail supply) to the preceding (left-
hand) modules is disconnected and a new supply provided for subsequent (right-hand)
modules.
With a new supply group it is also possible to refresh the module supply by providing a new
supply voltage. The 0 V supply on the module supply is never interrupted, but is always
looped through across the whole module bus.
You should always refer to the description of the relevant electronic supply voltage module.
The following modules are suitable for separating supplies, for example:
Electronic module
Base module
Module supply
Periphery supply
and C-rail

PSSu BS-R 1/8 S
PSSu BS-R 1/8 C
