Connectors
This section describes the connectors on the CVS-1450 device and includes
pinouts and signal descriptions for each connector.
Table 3-1 summarizes the functions of the connectors on the CVS-1450
device.
Power Connector
The power connector on the CVS-1450 device accommodates two power
supplies. The terminals labeled
V
and
C
provide the voltage and
common-mode signal for the main power of the CVS-1450 device. The
terminals labeled
Viso
and
Ciso
provide the voltage and common-mode
signal to power the isolated output circuitry.
Caution
The isolation provided by the CVS-1450 device is intended to prevent ground
loops that could introduce noise into the system. This isolation does
not
provide safety
isolation.
