CountermoduleUR20-1CNT-100-1DO(OrderNo.1315570000)
The counter module UR20-1CNT-1DO-100 can read sig-
nals (e.g. from an incremental encoder) with a max. input
frequency of 100kHz. The 32-bit counter can count up or
down within a predetermined range of values. The counter
can be controlled using software or externally through the
latch, gate and reset inputs. A digital output can be param-
etrized to be activated immediatly upon dropping below,
meeting or exceeding the set comparison value. In order to
make it possible for the PLC to always recognise the signal
in its sequential operations in case ofvery fast events, an
overrun time can be provided with the parameter Pulse du-
ration.
In counter mode, CH0A on plug-in connector 1 can be used
as the input and CH0B as a direction-detection input. In
incremental mode, an incremental encoder with track A and
B can be connected and at the same time supplied with op-
erating voltage. The control inputs are then connected to the
other plug-in connectors. A status LED is assigned to each
channel. The module electronics supply the connected sen-
sors with power from the input current path (U
IN
).
