Digital counter and communication modules
100/500 kHz; 32-bit counter resolution; individual
channel diagnosis
Incremental and absolute value encoders have become
indispensible in today’s automated systems.
Developed especially for these applications, Weidmüller
offers you various counter modules that can accept an
input frequency up to 500 kHz. The synchronous-serial
interface (SSI) module allows high precision positioning
tasks to be realised with absolute value encoders.
The module can be parameterised for listening or
master mode operation in order to cope with all fields
of application. A module with pulse input is available
to you for frequency measurement up to 100 kHz and
the UR20-1CNT-500 offers an input that can accept
frequencies up to 500 kHz. The UR20-2CNT-100 module
has two independent counter inputs; it is supplemented
with the UR20-1CNT-100-1DO module with one counter,
which however offers additional options thanks to a
latch, gate and reset input. This allows external control
of the counter. In addition, this module can trigger an
immediate event via a digital output using a set reference
value.
The UR20-1COM-232-485-422 module offers you
extended communication options; for example devices
can be integrated consistently in u-remote systems via
an RS232, RS485 or RS422 interface. The UR20-1COM-
SAI-PRO module presents a solution for connecting the
control cabinet to the field. This gateway allows the
integration of up to 15 decentral IP67 SAI-PRO Subbus
modules per u-remote module.
The module electronics supply the connected sensors
with power from the input current path (UIN).
