For a 8-channel analog input board with per-channel isolation, also see AI-218.

Pinout Same for both models

Noise Filtering Averaging engine that aver-

ages multiple samples to

improve resolution.

AI-217 has a simple analog

low-pass RC filter on the

front-end for anti-aliasing

designed for 60k-120kS/s.

Digital FIR filter for all chan-

nels with user-configurable

coefficients on back-end.

AI-217-1 has 128-tap FIR,

AI-217-803 has 512-tap.

Channel List Specifies the channels that

are to be read and the order

in which to read them. Thus,

the returned data is in the

order that the channel list

shows. If a channel needs to

be sampled more often than

other channels, the AI-207

allows the channel to be

entered more than once in

the channel list.

Specifies the channels that

are to be read, but because

they are simultaneously

sampled, the sequential

order concept does not

apply. The AI-217 always

returns data with the chan-

nels in numerical order

regardless of what order

they were in the channel list.

A channel may only appear

once in the channel list.
