What it is and where it fits
The Siemens 6AG1193-4CL30-7AA0 is a SIPLUS ET 200S terminal module — a spare part with conformal coating, built on the base of the standard 6ES7193-4CL30-0AA0. It serves as the wiring interface for a 2 AI TC High Feature electronic module, giving you spring-loaded terminal access to AUX1 with a continuous rating. This drops into a 15 mm slot on an ET 200S rail, typically specified when the panel sees condensation, corrosive gases, or salt spray — the coating buys you that margin. Operates from 0 °C to 70 °C ambient. Altitude rating up to 5 000 m with standard pressure derating curve. CE marked.
