PLC Interface for High Inrush Currents (Lamp Loads,
Capacitive Loads, Etc.) With Screw or Spring-Cage
Connection – PLC-R...1IC/ACT
1. Short Description
PLC interface, the narrow, plug-in, and flexible
modular interface system with a user-friendly plug-in
bridge system, now offers an extended range of relay
interfaces for special load applications, such as lamp
loads, capacitive loads and/or loads with increased
continuous current.
Lamp Loads and Capacitive Loads
The most difficult loads to manage include all loads
with high inrush currents. If the wrong relay is selected,
this can considerably shorten service life due to welded
contacts.
These heavy loads include all types of lamps that
cause high inrush currents due to their low cold
resistance. This category also includes loads that cause
high inrush peaks due to capacitors in the circuit. These
include energy-saving lamps, shunt-compensated
fluorescent tubes or types with electronic ballasts,
AC motors with starting capacitor, etc.
Inrush Currents up to 130 A
The 14 mm wide PLC-R...-24DC/1IC/ACT inrush
current relay offers the ideal solution with an N/O
contact designed specifically for these applications.
This relay safely manages short-term inrush peaks of
up to 130 A. The maximum permissible continuous
current is 6 A, when the double contact connections of
the relay are connected (e.g., with the FBST 14-PLC…
plug-in bridge) continuous currents of up to 10 A are
supported. The block is controlled with 24 V DC signals
directly from PLCs, IPCs or DDCs.
The actuator block version enables the connection
and bridging of lamp and motor return conductors,
which eliminates the need for additional return
conductor terminal blocks.
All Other PLC Advantages
The PLC-R…1IC/ACT series also features the other
advantages of the PLC range:
– User-friendly plug-in bridge system
– Integrated input wiring
– Relay can be quickly replaced using an engagement
lever
– Safe isolation between I/O
– Markers from the standard modular terminal block
range
– Cost-effective

Input wiring depends on the type, see Technical Data for input side.
Available for screw versions, provided for spring-cage versions.
3)
For voltages greater than 250 V (L1, L2, L3) between the same
terminal points on adjacent modules, the PLC-ATP insulating plate
(see INTERFACE catalog) should be fitted. FBST 8-PLC... or
FBST 500... can be used for potential bridging.
4)
The values in brackets are permitted if connections 13/13, 14/14, and
BB/BB are bridged.
5)
The PLC-ATP insulating plate (see INTERFACE catalog) should be
fitted between adjacent modules for safe isolation. FBST 8-PLC... or
FBST 500... can be used for potential bridging.

For torque of terminal block screws, see INTERFACE catalog.
For marking systems and assembly material, see CLIPLINE
catalog.
The dimensioning cross section (see INTERFACE catalog) refers to
simple wires without ferrules.
Inductive loads must be attenuated with an effective protective circuit
to protect inputs and outputs.
The PLC-ATP insulating plate should always be fitted at the start
and end of a PLC terminal strip.
