Data Sheet

Description
The
PLC-…-EIK 1-SVN 24…
electronic sensor terminal
block converts the variable resistance of a NAMUR sensor
into a digital signal that can be read by a PLC.
In addition, the internal circuitry monitors the sensor side for
a short circuit or wire break and indicates these errors via
the integrated LED.
Thanks to a corresponding resistance circuit, the
PLC-…-EIK 1-SVN 24… can be used to monitor all me-
chanical switches (N/C or N/O contacts) for short circuits
and/or wire breaks.
In addition to a high packing density, this switching amplifier
features the following:
– Stabilized supply voltage for the NAMUR proximity
switch
– Defined recognition and evaluation of the analog sen-
sor signal
– Monitoring of the sensor cable for short circuits and
wire breaks; a fault is indicated by the red LED
– Status display (high signal) via green LED
– 24 V/50 mA digital output for directly connecting pro-
grammable logic controllers
– Positive or negative error output depending on the
version
– Additional output for error messages
– Connection option for PLC V8 adapter
– Bridging and labeling with standard terminal block

The PLC-ATP BK insulating plate should be used in the following cases: always fit at the start and end of a PLC terminal strip for voltages
greater than 250 V (L1, L2, L3) between the same terminal points on adjacent modules (FBST 8-PLC... or FBST 500... can be used for
potential bridging) and for safe isolation between adjacent modules.
For other accessories such as power terminal blocks and plug-in bridges please consult the INTERFACE catalog and
