Counter module UR20-1CNT-100-1DO (Order No. 1315570000)
The counter module UR20-1CNT-100-1DO can read square-
wave signals (e.g. from an rotary encoder) with a maximum
input frequency of 100kHz. The 32-bit counter can count up
or down within a predetermined range of values. The coun-
ter’s basic functions are controlled by the coupler. In addition
the counting behaviour can be inuenced via the latch, gate
and reset inputs.
A digital output can be parameterised to be activated imme-
diatly upon either dropping below, meeting or exceeding the
set comparison value. An overrun time can be provided with
the parameter Pulse duration. Thus even a comparison
condition that exists only for a very short time can be eva-
luated at the output. Moreover the output can be set back
early in case the comparison condition is being met during a
longer period.
In signal mode Pulse and Direction, channel CH0A is
used as the input and channel CH0B as a direction-deter-
mining input. In incremental mode, an rotary encoder with
track A and B can be connected.
A status LED is assigned to each channel. The module elec-
tronics supply the connected sensors with power from the
input current path (I
IN
).
