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