Interface and Connectivity Features

The expansion rack contains two dedicated slots for SCALANCE W-700 series modules. Each slot includes a backplane connector that supplies power and data signals. The rack routes communication signals between the connected modules seamlessly. An integrated grounding terminal ensures proper system earthing for EMC compliance. The slot guides align modules precisely for secure and reliable connections.

Power Distribution Architecture

The Siemens 6GK1560-3AA00-0AU0 distributes the 24 VDC supply to both module slots. It handles a total current capacity of up to 5 A across both positions. The backplane PCB includes separate power and ground planes for current distribution. Each slot receives filtered and protected power through the backplane. The rack itself requires no external power connection independent of the modules.

Internal Construction and Component Details

A custom-designed backplane PCB forms the core of this expansion rack. This PCB contains copper traces for power distribution and signal routing. Two plastic guides align each module correctly during insertion. The steel chassis includes DIN rail clips for quick mounting and removal. Four mounting holes accommodate optional screw fixing for vibration-prone installations. The assembly includes 16 decoupling capacitors on the backplane for noise suppression.

Environmental Performance and Certifications

This expansion rack operates reliably from -40 °C to +70 °C in extreme industrial environments. It also withstands humidity levels from 5% to 95% without condensation issues. The 6GK1560-3AA00-0AU0 complies with UL 508, CSA, CE, and EN 61000-6-2 standards. These approvals ensure compatibility with global wireless automation installations.
