Siemens is expanding its modular Sitop PSU8600 power supply system to include a new single-phase 480-watt basic unit. The new product features four integrated monitored outputs with a total of 24 volts DC at five amperes per output. Each output is flexible and can be set during operation in a range between 4 and 28 volts either manually or remotely via software. This eliminates the need for additional power supply units to supply five or twelve volt loads. The CNX8600 expansion module can be used to monitor up to 36 total outputs. Thanks to its integration into the TIA (Totally Integrated Automation) Portal engineering framework, fast implementation in to the automation is supported. In addition, the Sitop Manager provides easy parameterization and diagnostics. Comprehensive diagnostic and maintenance information are also available via the two integrated Ethernet/Profinet interfaces and via OPC UA, and can be evaluated directly in the automation systems. This means that errors can be located quickly and reduces downtime.
