Power supply techniques
The DSCP6x series of signal conditioners
can be powered in three different ways.
First, the 24VDC power supply can
be connected directly to each signal
conditioner. Second, power can be
connected to one signal conditioner
and, using the expandable Power-Bus
connector, be distributed to a maximum
of 16 adjacent modules. Third, using
the DSCP70 Power Supply Connection
Module and the expandable Power-Bus
connector, power is distributed to a
maximum of 75 modules. See diagrams
to the right.
