What this backplane does and what the ratings mean
The 6AG1590-0BL00-7AA0: This is the SIPLUS version of the 6ES7590-0BL00-0AA0 active backplane – it provides the backplane bus and 12 slot positions for S7-1500 IO modules in an ET 200MP station, supporting hot swapping during operation. The extended temperature range of -40 to +70 °C in horizontal installation and the conformal coating (Class A) mean it survives condensation, frost, and corrosive atmospheres where a standard backplane would fail. Width of 434 mm dictates the mounting rail and cabinet space – you need the matching S7-1500 rail and allow room for the slot covers and modules. Depth is only 14 mm, so it sits flush on the rail. The active backplane bus supplies up to 2 W of power to the modules and supports isochronous mode and firmware update, making it suitable for motion control and PROFINET IRT applications.
Production status and environmental compliance
Rated for installation altitudes up to 5 000 m, with derating above 2 000 m per the manual. Resistant to diesel, oil droplets, coolants, salt spray, and harmful gases (levels GX, LC3, LB3). Type 1 protection against fouling keeps particulates and films from degrading creepage distances.
Sourcing and fit confirmation
Because the backplane defines the physical rack for an ET 200MP station, confirm that the mounting rail and slot covers are ordered separately. The backplane itself accepts up to 12 single-width modules, with a maximum of 1 IM and 12 power supplies or IO/CM/CP/TM modules per station. For a BOM line requiring this exact order code, we can quote against your requirement – the part is available for procurement without lifecycle risk.
