The Siemens 6ES7400-1JA00-0AA0 is a SIMATIC S7-400 UR2 rack with 9 slots, designed for both centralized and distributed I/O configurations in an S7-400 system. It mounts in a standard 19-inch cabinet or panel and accepts S7-400 power supplies, CPUs, and I/O modules in the 9 available slots.
This rack is classified at a mature lifecycle stage, meaning it is no longer in active new-production runs but remains available through our sourcing channels for BOM fills, line-down replacements, or expansion of existing S7-400 installations. We source this part to order against an RFQ; lead time and pricing depend on current availability from our multi-region supply network.
