Digital counter module UR20-2CNT-100 (Order No. 1315590000)
The digital counter module UR20-2CNT-100 can read
square-wave signals (e.g. from an rotary encoder) with a
maximum input frequency of 100kHz. Depending on the
operating mode, both 32-bit counters can count up or down
independent of each other in a preset range of values.
In signal mode Pulse and Direction, channel CH0A and
CH1A respectively is used as the input, channel CH0B and
CH1B respectively is used as a direction-determining input.
In incremental mode, an incremental 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
).
