The NI 9205 provides connections for the 32 single-ended or
16 differential analog inp
u
t channels, as well as one digital inp
u
t
channel, one digital o
u
tp
u
t channel, COM, and AI SENSE.
Note
The digital o
u
tp
u
t channel is s
u
pported only in
CompactRIO systems.
The NI 9205 with spring terminal has a 36-terminal detachable
spring-terminal connector, and the NI 9205 with DSUB has a
37-pin DSUB connector. Each analog inp

t
device. The NI 9205 is capable of an aggregate sampling rate of
250 kS/s. The NI 9205 also s
u
pports triggering. Refer to the
software help for information abo
u
t inp
u

programmable gain instr
u
mentation amplifier and are m
u
ltiplexed
to an ADC. Each channel also has
±
30 V overvoltage protection.
For more information abo
