Digital input modules P- or N-switching; Reverse
polarity protection, up to 3-wire +FE
Digital input modules from Weidmüller are available
in different versions and are used primarily to receive
binary control signals from sensors, transmitters, switches
or proximity switches. Thanks to their flexible design,
they will satisfy your need for well co-ordinated project
planning with reserve potential.
All modules are available with 4, 8 or 16 inputs and
comply fully with IEC 61131-2. The digital input modules
are available as P- or N-switching variant. The digital
inputs are for Type 1 and Type 3 sensors in accordance
with the standard. With a maximum input frequency of up
to 1 kHz, they are used in many different applications. The
variant for PLC interface units enables rapid cabling to the
proven Weidmüller interface sub-assemblies using system
cables. This ensures rapid incorporation into your overall
system. Two modules with a timestamp function are able
to capture binary signals and to provide a timestamp
in 1 μs resolution. Further solutions are possible with
the module UR20-4DI-2W-230V-AC which works with
accurant current up to 230V as an input signal.
The module electronics supply the connected sensors
from the input current path (UIN).

Potential-distribution modules; system accessory
A wide range of accessory modules is available
for individual requirements of machine and plant
engineering. Various potential distribution modules
are available for the supply of sensors with 2- to 4-wire
connection technology directly from the remote I/O
system. These offer 16 "PUSH IN" potential points and
supply your application with any auxiliary potential
available. An empty module, where the system bus and
voltage supply are looped through, allows you to plan
expansion slots in a system and to start these up without
any interruptions if required.
