Digital counter module UR20-1CNT-500 (Order No. 1315580000)
The digital counter module UR20-1CNT-500 includes a
RS422 interface for recording difference signals (e.g. from
an differential rotary encoder) with a maximum frequency
of 500kHz. The 32-bit counter can count up or down in a
preset range of values. The counter‘s basic functions are con-
trolled by the coupler. Via a reset the counitng value can be
set to zero.
In signal mode Pulse and Direction, channel CH0A is
used as the input, channel CH0B is used as a direction-
determining 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
electronics supply the connected sensors with 5VDC or
24VDC from the input current path (I
IN
).

Connection diagram UR20-1CNT-500
– One 32-bit counter, invertible, RS422, max. 25VDC
– Counting frequency 500kHz max. (A/B channel, 1/2/4-
times sampling or pulse and direction)
– input filter (parametrisable)
– Comparison value, set value
– Alarm and diagnostic function with μs time stamp
– μs time stamp for value counting (e.g. for speed measure-
ments)
Twisted-pair cables with additional foilscreen
(SF/UTP) have to be used to connect the rotary
transducer.
