Description
:
The PE12316 TRIPLE INCREMENTAL ENCODER INTERFACE consists of three channels each,
which can independently determine the direction of displacement of a mechanical or axis based device
on two input signals from transducers in quadrature. Alternatively, each channel can measure a pulse
width using a known clock rate, or a frequency, by counting input pulses over a known time interval. It
includes three 16/24-bit counters which may also be used separately. The PE12316 may be cascaded
between channels on one device or between devices to provide accuracy greater than 16/24-bits, and
is designed for use in many microprocessor-based systems.
