Bus module for tough environments — 2 slots, wide temperature range
The Siemens 6AG1193-6BR00-7HM0 is the SIPLUS version of the ET 200SP BU type M0 base unit, built from the standard 6ES7193-6BR00-0HM0. It provides two slots for R1-capable interface modules, giving you the environmental range that matters when the panel sits outdoors or near process heat. Vertical mounting holds to 50 °C maximum; horizontal keeps going to 70 °C, with a cold floor at -40 °C including frost and condensation. That means it can handle washdown zones, cold stores, and desert cabinets without derating. Rated supply is 24 V DC, isolated from the backplane bus (tested at 707 V DC type test). The bus module measures 100 mm wide × 141 mm high × 29 mm deep — a slim footprint that leaves space for signal modules and termination boards in the same profile.
What uses this class — ET 200SP distributed I/O racks
Backplane carrier for an ET 200SP I/O station. Supplies the IM and signal modules via backplane bus. BU type M0 supports PROFINET R1 redundancy with two slots for the IM and server module.
