What this module does in a dirty, cold, or hot cabinet
The Siemens 6AG1193-6PA00-7AA0 is a SIPLUS ET 200SP server/termination module — the ruggedized version of the standard 6ES7193-6PA00-0AA0, carrying conformal coating and a wider environmental envelope. It provides the backplane bus connection and mechanical mounting for one ET 200SP I/O slice, occupying a single 7 mm wide slot. Width is 7 mm, depth 36 mm, height 117 mm. The temperature range runs from -40 °C to 70 °C, including condensation and frost at the low end. That's the full span without derating — important for refrigerated areas, outdoor cabinets, or unheated plant floors. At altitude, the module holds its temperature rating to 2 000 m (-1 000 m to +2 000 m), then derates by 10 K up to 3 500 m and by 20 K up to 5 000 m.
