Siemens 7KM9900-0XA00-0AA0 SENTRON PAC USB Cable Adapter, 3 m, Black/Grey

Where generic USB converters merely bridge physical connections, the Siemens 7KM9900-0XA00-0AA0 cable adapter opens a direct, electrically isolated channel to the SENTRON PAC family. This 3-metre adapter turns a standard USB Type-A port into a proprietary service interface for parameterization, data readout, and diagnostics of PAC3100, PAC3200, PAC4200, and 7KM9300 devices. No intermediate hardware, no protocol guesswork—just plug-and-play communication backed by Siemens powerconfig software.

Highlights

• Direct USB Type-A to SENTRON PAC service interface
• 3 m cable length for flexible field or bench use
• Electrical isolation protects both PC and measuring device
• Compatible with PAC3100, PAC3200, PAC4200, and 7KM9300
• Rugged PVC/plastic construction, black/grey finish
• Operates from -25 °C to +70 °C

In daily use

Connect the adapter to any Windows PC, install the Siemens USB drivers, and launch powerconfig. The adapter enumerates as a virtual COM port, allowing you to set parameters, read energy values, update firmware, and perform service functions on the connected PAC device. The 3-metre length reaches devices inside enclosures without straining the connector, while the isolation barrier prevents ground loops that can corrupt measurements or damage ports.
