Its 482.5 mm aluminum profile supports central, distributed and expansion configurations with the documented S7-400 module placement rules.
Key Functions
Dual-Segment Rack
Provides two sections with nine single-width slots each.
Separated Backplane Buses
Separates both the I/O bus and communication bus between the two rack systems.
S7-400H Mechanical Platform
Accommodates redundant and standard S7-400 hardware in central or expansion arrangements.
