The SIEMENS 6ES7400-2JA00-0AA0 is a UR2-H backplane rack for the SIMATIC S7-400H series. This rack is designed to house two central racks or expansion racks within a single unit, suitable for compact setups of redundant S7-400H systems.
The Siemens 6ES7400‑2JA00‑0AA0 is a UR2‑H universal mounting rack engineered exclusively for SIMATIC S7‑400H redundant controller systems, designed to consolidate two electrically isolated 9‑slot subracks into a single physical chassis for compact, fault‑tolerant industrial automation deployments.
Originating from Germany, this rack delivers dual‑segment electrical isolation (P‑bus, communication bus), 18 total single‑width slots, and compatibility with S7‑400 CPUs, power supplies, I/O, CPs, and IMs—making it ideal for centralized or distributed redundant setups in process control, energy, and discrete manufacturing requiring 24/7 uptime.
It integrates seamlessly with TIA Portal, supports hot‑swap module replacement, and meets global compliance standards (UL, CE, FM, RoHS), balancing rugged mechanical design with deterministic backplane communication for critical applications like chemical plant safety interlocks, power generation turbine control, and automotive assembly line redundancy.
