Succession of TX devices on TX rails

If more than one TX rail is required, bus connection modules are required. If island bus expansion modules are used, a power supply module is required as well. See the TX-I/O planning and installation manual, CM110562, for the correct place of these devices on the rail and their wiring.

Bus power supply ¹⁾

The internal bus power supply has to be configured using one of the following settings.

Manual off: Internal bus power supply is permanently off.

Auto detection depending on connected devices: Internal bus power supply is automatically turned off if no TX- I/O modules are connected to the TX rail.

Manual on: Internal bus power supply is permanently on.

Auto detection depending on connected devices

Total power available

Total power available shows the sum of the powers of the internal power supply of the TX rail and the power supply modules on the TX rail.

The value is calculated automatically.

Unit: [mA]

600

Power remaining

Power remaining shows the remaining power of the TX rail.

The value is calculated automatically, based on the power consumption of the power supply modules and TX modules that consume power.

Unit: [mA]

Note:
If the value of the internal power supply of the TX rail is exceeded, a TXS1.12F4 Power supply is automatically added to the TX rail.

600

¹⁾ If the subsystem-specific extension TX-I/O (FldBusMgmt - subsystem-specific extension) of the BACnet object Field bus management object (FldBusMgmt) is enabled, you have to configure this property in the BACnet objects editor or in Web interface.

Internal island bus supply

DC 24 V

The internal bus supply can typically power 8 TX-I/O modules. See TX-I/O planning and installation manual CM110562 for details.

For consumption data of TX devices see table below.

max. 600 mA

TXS1.12F4

TXS1.12F10

The internal bus supply can be reinforced by external power supply modules (may be operated in parallel).

See TX-I/O planning and installation manual, CM110562 for details.

1200 mA

TXS1.EF4

TXS1.EF10

These are pure island bus connectors and do not supply any power to the modules.

Power consumption of modules on TX rails

Following table shows the consumption data DC 24 V per I/O point and for TX accessories. Values in mA.
