difference between the terminals is within the input low range,
the channel registers as low.
Note
Refer to the
NI 9361 Datasheet
on
for more information about digital logic
levels.
Incremental Encoders
Incremental encoders typically have channel A and channel B.
By monitoring both the number of pulses and the relative phase
of channels A and B, you can track both the position and
direction of rotation. Some encoders have a third channel,
channel Z, which is also referred to as the index channel. A high
level on channel Z causes the counter to be reloaded with a
specific value in a specific phase of a cycle.
Connecting Single-Ended Incremental Encoders
You can connect single-ended incremental encoders to the
NI 9361.
