PLC INTERFACE With SPDT Relay,
High-Current Version
INTERFACE
Data Sheet
100221_03_en
Description
A number of applications such as electrical heating systems
require higher continuous load currents than miniature
relays can carry and switch.
Long Electrical Service Life
The above-average service life of the contacts is particularly
noticeable in the mid-load range when compared with less
powerful relays. On average, the interval between servicing
can be doubled or tripled, thus reducing costs.
Rugged SPDT Relay for Higher Loads
The abbreviation "HC" in the designation stands for
"High Current" applications with up to 10 A continuous
current. The block contains a 16 A power relay with
PDT contact application, so that additional reserves are
used if overdimensioning occurs, e.g., in the event of
temporary overload. The relay is secured against vibration
by a captive retaining bracket and can be replaced if it
becomes worn without having to remove the wiring. The
relay is sealed with RTII protection to protect the relay
mechanics against external influences such as dust.
Vibration-Resistant Plug-In Bridge System Reduces the
Amount of Wiring Required
Another feature of the PLC series is the FBST 500 plug-in
bridge system, which can be cut to any length. It can be
plugged into the control and/or contact side "with a click"
and snapped into place to ensure vibration-resistant
connection. Up to 35 PLCs can be clearly connected
"to the block" within seconds, without any errors.
Additional user-friendly wiring is provided by the contact
connections arranged in pairs, if more than one conductor
has to be connected per contact.

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.
