The Siemens 6ES7400-1JA11-0AA1 is a UR2 XTR S7-400 rack designed for central or distributed use in SIMATIC PCS 7 systems. It provides 9 slots and supports two redundant power supplies. The XTR designation means it carries conformal coating (ISA-S71.04 severity levels G1, G2, G3) and an extended operating temperature range of 0 °C to 70 °C, making it suited for harsh or uncontrolled environments like chemical plants, offshore platforms, or outdoor enclosures.
Certifications and approvals
The rack carries CCC, CE, UKCA, FM, KC, UL, EAC, and RCM approvals. That covers global installations including China, Europe, North America, South Korea, Russia, and Australia. The conformal coating and extended temperature rating are factory-applied and tested; no field coating is required.
