More Information

Overview Manuals Rack Architecture Power Redundancy XTR Environment Product Applications

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.

  • Capacity: Nine module slots.
  • System family: SIMATIC S7-400 and PCS 7 station hardware.
  • Deployment: Supports central or distributed configuration.
  • Backplane: Provides the mechanical and bus connection for installed modules.
  • Dual supply: Two redundant power-supply modules can be installed.
  • Availability: A redundant supply design can reduce loss from one PS failure.
  • Engineering: Confirm the exact PS pair and incoming feeds.
  • Service: Isolate both supply paths before rack work.
  • Temperature: Extended-temperature design broadens cabinet use.
  • Coating: Conformal coating improves resistance to environmental contamination.
  • Grounding: Preserve rack bonding and shield connections.
  • Selection: Do not replace the XTR article with a standard rack without environmental review.
  • PCS 7 process stations: Forms the rack for controller and communication modules.
  • Redundant control: Supports two power supplies in high-availability designs.
  • Remote stations: Provides a defined distributed S7-400 module chassis.
  • Harsh cabinets: Uses XTR temperature and coating features in demanding environments.
Description
6ES7400-1JA11-0AA1 provides the nine-slot mechanical and electrical backplane for a SIMATIC S7-400 central or distributed station. It accepts S7-400 modules in a defined rack layout and supports two redundant power-supply modules, making it suitable for PCS 7 architectures that need higher availability.

6ES7400-1JA11-0AA1 is the extended-temperature, conformal-coated UR2 XTR variant. That environmental design gives engineers a clear advantage in demanding control rooms and process cabinets, while the exact slot plan and bus arrangement keep controller, communication and I/O modules organized for maintenance.
Technical notes
Confirm the installed rack article, slot allocation, redundant power-supply design and backplane-bus requirements before replacing 6ES7400-1JA11-0AA1. The rack supports nine S7-400 slots but does not make every module combination interchangeable. De-energize both supply paths, preserve grounding and shielding, and verify all bus connectors before restoring the station.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
How many slots does 6ES7400-1JA11-0AA1 provide?
6ES7400-1JA11-0AA1 provides nine S7-400 module slots in the UR2 XTR rack.
Can 6ES7400-1JA11-0AA1 use redundant power supplies?
Yes. The rack can accept two redundant power-supply modules, but the exact supply pair and incoming feeds must be engineered together.
What does XTR mean for 6ES7400-1JA11-0AA1?
It identifies the extended-temperature, conformal-coated rack variant for more demanding environmental conditions.
Can 6ES7400-1JA11-0AA1 be used as a distributed rack?
Yes. Siemens specifies it for central or distributed S7-400 configurations; confirm the required interface modules and bus layout.
What should be recorded before replacing 6ES7400-1JA11-0AA1?
Record every slot, module order number, power-supply feed, interface-module position, grounding point and backplane connector condition.
Can a standard UR2 rack automatically replace 6ES7400-1JA11-0AA1?
Do not assume so. The XTR temperature and conformal-coating requirements must be reviewed before accepting a standard environmental variant.
