PCL-833-BE - Advantech CIRCUIT BOARD, 3-Axis Quadrature Encoder & Counter Card
PCL-833 is a 3-axis quadrature encoder and counter add-on card for the
IBM PC/AT and compatibles (ISA bus). This card lets your PC perform
position monitoring for motion controlsystems. Each input includes a
decoding circuit for incremental quadrature encoding. Inputs accept
either single-ended or differential signals. Quadrature input works with
or withoutan index, allowing linear or rotary encoder feedback.PCL-833
has three independent 24-bit counters. The maximum quadrature input rate
is 1.0 MHz, and the maximum input rate in counter mode is 2.4 MHz. You
can individuallyconfigure each counter for quadrature decoding,
pulse/direction counting or up/down counting.
PCL-833 provides five
digital input channels. Each channel accepts digital input as an index
input for a rotary encoder or as a home sensor input for a linear
encoder. The card cangenerate an interrupt to the system based on a
signal from its digital inputs, overflow/underflow of its counters, or
on a programmed time interval. It can repeatedly generate interruptsat
any time interval you specify, from 0.1 msec. to 255 sec. These
interrupts let you precisely monitor the speed of a control system.
