   Communications 

Interface type 

Siemens specific protocol 

   DC output 

Nominal voltage 

DC 24V 

 

Max. current  

600 mA  

(sufficient for typically 8 TX-I/O modules) 

 

Parallel switchable with 3 supply 

modules TXS1.12F10  

For details, see: TX-I/O planning and 

installation manual, CM110562)  

 

Short-circuit proof, overload-proof 

Self-resetting 

 

Protection 

Short-circuit proof 

Island bus connector on 

side 

Protection against faulty wiring with 

AC 24 V 

No electric protection. 

Use the terminal cover. 

 

 

 

KNX PL-Link interface 

 

 

    Communications 

Interface type 

KNX, galvanically separated 

 

Transceiver 

TP-UART 

 

Baud rate 

9.6 kbps 

    Bus power supply 

Nominal voltage 

DC 29 V 

 

Max. supply  

 

Note: for devices with higher power 

requirement, use the output AC 24 V 

2 A, see above.

 

160 mA for max 32 devices with KNX 

PL-Link. Default: Auto detection; must 

be turned off via ABT if external bus 

supply is used. 

Up to 64 devices with KNX PL-Link can 

be operated using one or two external 

bus supplies. 

 

Protection  

Short-circuit proof  

Protection against miswiring up to AC 24 V 

 

 

 

DALI interface 

 

 

    Communications 

Interface type 

DALI, galvanically separated  

 

Baud rate 

1.2 kBit/s 

 

Insulation strength 

Reinforced insulation for 230 V (1.5 kV) 

Suitable for installations in overvoltage 

category III (4 kV). 

    Bus power supply 

Nominal voltage 

DC 16 V 

 

Max. current  

128 mA for max 64 DALI devices 

 

Protection  

Short-circuit proof  

Upon power-on, AC 230 V bus voltage is 

recognized on terminals DA+ and DA–. 

 

NO protection against miswiring with AC 24 V or AC 230 V: 

Voltage between DA+ / DA+ or between DA– / DA– will destroy the DALI PCB!
