SDM-CVO4 4-Channel Current/Voltage Output Module
7
6. Specifications
Operating voltage
:
12 VDC nominal (8 V to 16 V)
Current drain at 12 VDC
: Typical active quiescent current 27 or 54 mA,
depending on operating mode (no load on output
ports). To estimate the total current, add the
quiescent current to the sum of all output currents
multiplied by 1.5.
For example, if each port is at 10 mA output, the
total = 54 + (1.5*4*10) = 114 mA. The device
can be shut down to <0.5 mA with all outputs off.
Maximum total
SDM cable length:
6 m (20 ft) if the
SDMSpeed()
CRBasic
instruction is not used. Longer cable lengths may
be acceptable if
SDMSpeed()
is used.
Operating temperature:
–25 to 50
°
C standard (–40 to 80
°
C optional)
Size:
176 mm wide x 111 mm high x 24 mm deep
234 mm wide x 111 mm high x 24 mm deep
when fitted with brackets for mounting in
enclosure. Mounting brackets have two holes at
203.2 mm (8 in) spacing for screw fixings.
Weight:
370 g
EMC status:
Complies with EN55022-1:1998 and
EN50082-1:1998
