Siemens 6ES7400-2JA10-0AA1 SIMATIC PCS 7-400 UR2-H XTR Rack
01Overview
Siemens 6ES7400-2JA10-0AA1 is the UR2-H XTR rack for SIMATIC PCS 7-400 systems requiring an extended environmental design. The rack provides two independent segments with nine slots each and supports two redundant power-supply positions per segment. Conformal coating and the extended-temperature XTR design distinguish this article from the standard UR2-H rack, so the complete PCS 7 hardware approval and environmental requirement must be matched by exact article number.

03Features
Key Functions
- Two independent nine-slot segments support a complete high-availability PCS 7 station arrangement.
- Two redundant power-supply positions are available on each segment.
- The XTR design provides an extended environmental version of the UR2-H platform.
- Conformal coating supports the documented enhanced environmental design.
- Separate communication-bus and P-bus paths preserve the two-segment architecture.
- The rack supports central or distributed use when all installed modules are approved for the intended system and environment.
Product Identity
- Manufacturer: Siemens
- Model: 6ES7400-2JA10-0AA1
- Product Type: SIMATIC PCS 7-400 UR2-H XTR segmented rack
- Status: Active product
04Applications
- PCS 7 automation systems requiring the documented XTR environmental design.
- High-availability control stations with two nine-slot hardware segments.
- Projects requiring conformal-coated rack hardware as part of an approved environmental concept.
- Central and distributed PCS 7-400 station configurations.
- Service replacement of an existing UR2-H XTR rack with the same full article number.
- Industrial installations where redundant power-supply positions are required on both rack segments.
05Lifecycle
- Siemens identifies the exact UR2-H XTR article as an active product.
- Match the XTR and conformal-coating requirement across the complete installed hardware; a standard UR2-H rack is not automatically equivalent.
- Record both rack segments, power modules, controllers, interface modules and approved environmental conditions before replacement.
- Maintain the documented clearance, mounting, grounding and cabinet-climate requirements.
- After installation, validate both segments, redundant supplies, system communication and all PCS 7 diagnostics.
06FAQ
What is Siemens 6ES7400-2JA10-0AA1?
It is the UR2-H XTR segmented rack for SIMATIC PCS 7-400 central and distributed system configurations.
How many slots are provided?
The rack has two segments with nine slots each, giving eighteen module positions.
What distinguishes the XTR version?
The exact article is specified with an extended-temperature design and conformal coating.
How many redundant power supplies can be positioned?
The product description specifies two redundant power-supply positions for each of the two rack segments.
Can a standard UR2-H always replace this rack?
No. The XTR environmental design, conformal coating and complete PCS 7 approval must be verified before any substitution.
What should be verified after installation?
Verify both segments, power redundancy, all module positions, communication paths, system diagnostics and the approved environmental operating conditions.
