Safety warnings
Attention: Electrical equipment must be installed and fitted only
by qualified electricians.
To prevent electric shocks, disconnect the mains supply (by
cutting out the circuit breaker) before working on the device.
or on the load. Failure to observe any of the installation
instructions may result in fire and in other hazards.
Function
Important:
The relay station is
not
a KNX / EIB device.
The relay station is equipped with 8 potential-free load contacts (n.o.
contacts) for a maximum current of 10 A each for the switching of
different loads, e.g. lighting.
The relay station can be operated as a momentary-contact (toggle
mode) or as a maintained-contact (doorbell mode) actuator.
The station is controlled with an AC/DC 24V 20 mA touch sensor (e.g.
Art. no. ..2248..) or with mechanical pushbuttons.
The output terminals A1‘ – A8‘ can be used for the connection of
checkback LEDs.
The relay station supplies the control voltage (positive pole) for the
switching inputs (E1-E8) and the common ground line for the
checkback LEDs at its DC output
Operation
The relay station is operated by means of the connected touch
sensor.
The red LEDs (1) of the relay station indicate the switching state of
the relay contacts.

Fitting
Fit the relay station by snapping it onto a mounting rail as per DIN EN
50022.
Installation:
Connect the supply voltage AC 230 V ~ for the relay station to
terminals "L" and "N", see fig.
A
.
Connect the loads to be switched to the output terminals
A1 – A8
of
the relay station, see fig.
A
. The illustration shows 3 lamps connected
to different phase conductors. The remaining terminals are connected
in the same way.
The schematic in fig.
B
shows the relay station used in combination
with the AC/DC 24V 20 mA touch sensor.
Mechanical pushbuttons, e.g. 534U, can be used as an alternative.
Connect the switching inputs of the relay station
E1 – E8
with outputs
1 - 8 of the touch sensor (e.g. Art. no. ..2248..).
The schematic in fig.
B
is a wiring example. The remaining terminals
are connected in the same way.
Connect the LED inputs 1 - 8 of the touch sensor with the output
terminals
A1‘ – A8‘
(DC 24 V, 10 mA) of the relay station.
The schematic in fig.
B
is a wiring example. The remaining terminals
are connected in the same way.
In this case, the switching state of the relay contacts is indicated by
the LEDs of the touch sensor

Connect the 24 V DC output (4) of the relay station with the correct
polarity to the touch sensor, see fig.
B
.
Important:
In the event of a short-circuit at the DC output,
the station will no longer accept commands from the
pushbutton.
the relays will switch off briefly (ca. 1 s).
