The Siemens 6AG1153-2BA10-7XB0 is a PROFIBUS DP interface module for the ET 200M distributed I/O system, built to the SIPLUS extreme spec with a -40 to 70 °C operating range. It communicates at up to 12 Mbit/s over RS-485, handles 244 bytes each of inputs and outputs, and draws a maximum 650 mA from a 24 VDC supply. The firmware ships at V6.0.0, and it supports STEP 7 configuration as well as third-party DP masters importing the GSD file SI05801E.GSG.
If you're dropping this into an existing ET 200M station, the 40 mm width and the standard mounting scheme mean it fits the same backplane slot — no panel rework. The I²t value of 0.1 A²·s is what you'd pass to the panel builder for backplane fuse coordination; the inrush current typ 3 A helps size the 24 V supply branch. The temperature range covers non-conditioned cabinets, so no heater is needed for cold starts down to -25 °C (cold restart minimum).
