General
As opposed to mechanical contactors,
electronic load relays offer the benefit of a
practically unlimited service life and a high
operating speed for functions.
Optocoupler technology enables a non-
contacting, bounce-free and wear-
resistant switching of phase loads With a
switching frequency up to 10 Hz, a
considerable increase in economic
efficiency can already be seen compared
to conventional, electromechanical
components. Electronic relays are
primarily used as output elements by
programmable controllers.
An additional RCV protective circuit of the
outputs enables a continuously reliable
operation.
Electronic three-phase contactor
The solid-state relays can switch inductive
loads such as motors on and off during
zero voltage operation.
Electronic reversing contactor and DC
motor driven relay
Apart from switching on and off, the
reversing contactor allows a change in the
direction of travel for three-phase
inductive motors. The DC motor-driven
relay performs the same function for DC
motors.
Further characteristics include a reciprocal
closing lockout as well as a fixed
minimum changeover time between anti-
clockwise and clockwise rotation.

Thermistor overload relay
TMS 101
General
The electronic thermistor overload relay
monitors the windings of electrical
machines in connection with PTC
thermistor detectors. During usage,
reliable protection against thermal
overload is guaranteed. A bimetal
overload trip unit is not required.
The areas of application are:
Function and structure
The thermistor overload relay TMS 101
evaluates up to six series-connected PTC
resistors.
Three-phase inductive motors are usually
fitted with three sensors. Pole-changing
three-phase inductive motors with
separate winding require six sensors. The
relay is energised in normal operation i.e.
the permitted temperature level has not
been exceeded. If the temperature rises
above the defined value, which occurs in
conjunction with an increase in resistance,
the relay drops out. The motor is
simultaneously disconnected and the fault
indicator lights up.
Due to an internal memory circuit, the
motor remains switched off until the reset
resistance is reached and the ‘reset’
button (internal or external) is pressed.
Only then is it possible to start up the
motor again. To detect a wire breakage,
the sensor cables operate using a closed
circuit current methodology.

Monitoring modules
General
The increasing automation and
centralisation of electrical installations
requires more feedback information from
the process to guarantee an error-free
functional sequence.
Three-phase system monitoring
The most simple and effective way to
monitor a three-phase network is to
measure the under-voltage. The process
involves recording each phase so that a
voltage drop is immediately detected.
A signal is generated if the voltage falls
below 85% of the mains voltage
(according to VDE 0108).
Three-phase fuse monitoring
Three-phase induction motors are
particularly at risk when a phase fails. The
three-phase fuse monitoring is specially
designed for monitoring supply leads of
three-phase induction motors for which
system monitoring is not suitable.
Rotation indicator
The rotation indicator monitors the phase
sequence L1-L2-L3 which determines the
direction of rotation for three-phase
induction motors. If the phase sequence
of the monitored three-phase network is
incorrect, the relay of the rotation indicator
remains open.
Lamp test module
The test module is designed for 14
indicator lights.
It is used for:
Fuse module
The module has been designed for 4
miniature fuses for control circuits.
The fuse module can be used for 12 to 24
V (with LED failure indicator) or 110 to 220
V (with neon lamps failure indicator).
