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.

LED on 

 

relay contact closed open 

LED off

 

 

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  

 

relay contact closed 

LED on 

 

relay contact closed open 

LED off 

 

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).
