Operating instructions
8-channel relay station
1. 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.
2. 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.
3. 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.

4. Installation
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).

Commissioning
Pushbutton (2) and LED (3) are accessible only during the fitting and
installation activities, see fig. A. For switching over between the two
modes of operation press the pushbutton (2) for at least 7 s. The selected
opmode is stored in a non-volatile memory. The device is delivered
preset to the toggle mode.
doorbell mode LED (3) lit up red; the relay contact is closed as
long as them control pushbutton is kept depressed.
toggle mode LED (3) lit up green the relay contact is closed or
opened after each press of the control pushbutton.
Response to mains failures
After a mains failure, all relay contacts are open and must be activated
again.
Troubleshooting
If an undefined fault occurs during operation of the device, the LED (3)
lights up yellow. Acknowledge the fault by pressing the pushbutton (2) for
ca. 1.5 s. The relay station is then in the toggle mode. If necessary,
switch over to the other opmode, see commissioning.
