SCC-PWR01
The SCC-PWR01 co5 V to ±15 V, which is the analog power
supply that SCC modules use. Set switch S1 on the SCC-PWR01 to select
the source of the +5 V as either
E SER
(E/M Series) or
EXT
(external). If
you select
E SER
, the SCC-PWR01 uses +5 V power from the E/M Series
DAQ device. If you select
EXT
, you must connect a +5 V supply (user
supplied) to the screw terminals of J1 on the SCC-PWR01. Wire the
positive lead to the screw terminal labeled
+
5 V
and wire the negative lead
to the screw terminal labeled
GND
. If you are using the SC-2345 carrier,
pass the leads through the strain relief on the front of the enclosure. If you
are using an SC-2345/2350 with configurable connectors, use a strain-relief
panelette for the leads.
