Features:
- Nine-slot backplane: Organizes S7-400 processing, communication and I/O modules.
- Redundant supply capacity: Accepts two power-supply modules for higher availability.
- XTR construction: Adds extended-temperature capability and conformal coating.
6ES7400-1JA11-0AA1 is the physical rack and backplane foundation for a nine-slot S7-400 or PCS 7 station.
Its UR2 layout supports both central and distributed configurations while keeping module positions and bus connections defined.
The XTR environmental variant is intended for installations that require wider temperature tolerance and coated electronics.
For 6ES7400-1JA11-0AA1 sourcing, Apter Power can help confirm rack layout, power-supply redundancy and installed module compatibility. Siemens 6ES7400-1JA11-0AA1 is listed as SIMATIC S7-400 UR2 XTR 9-Slot Rack.
