Use this expansion module from Siemens to transmit signals between processors and control devices. When combined with a PSU8600 power supply unit (PSU), it can provide multiple integrated outputs with selective monitoring. This results in a more versatile PSU with numerous uses. The unit comes complete with TIA (totally integrated automation), so you can set voltage and current response thresholds individually for each output of the system. You can then monitor selective outputs in order to quickly find faults and diagnose problems. The product benefits from a three-colour LED display so you can easily check its operating status.

• Diagnostic and maintenance information is available via PROFINET, offering fast transmission of data suitable for automation, logistics and oil and gas industries
• DIN rail mounting for straightforward and fast installation
• PROFIenergy allows for specific activation or deactivation of outputs depending on energy consumption, which helps to reduce energy use

Yes, it's possible to add more modules – such as those used for buffering short power failures – to this versatile system.
