6ES7400-1JA11-0AA0 SIMATIC S7-400 UR2 universal rack. 18 slots (9+9 split), accepts S7-400 CPUs, signal/power modules, IM modules. For central or distributed S7-400 configurations.
Product Overview
6ES7400-1JA11-0AA0 is a SIMATIC S7-400 Universal Rack UR2 (18-slot) — the standard mechanical chassis for mounting S7-400 CPUs (e.g., CPU 414-2, 416-2), power supplies (PS 407), signal modules (SM 421/431, SM 422/432), interface modules (IM 460/470 for distributed I/O extension), and communications processors. The UR2 has 18 module slots divided into two 9-slot segments (left/right), which can host a CPU + I/O in a central rack or be split between a central and expansion configuration with appropriate interface modules. It is the go-to rack for medium-to-large S7-400 control cabinets.

Product Family
SIMATIC S7-400 — Rack / Chassis
Rack Type
UR2 (Universal Rack — 18 Slots)
Total Slot Count
18 Slots (Split: Slot 1–9 Left Segment / Slot 10–18 Right Segment)
Slot Assignment (Typical Central Config)
Slot 1: PS 407 (Power Supply) Slot 2: CPU (or CR with IM) Slots 3–9: SM / FM / CP (Left Segment) Slots 10–18: SM / FM / CP (Right Segment — if no 2nd CPU)
Backplane Bus
S7-400 Parallel Bus (I/O, K-Bus for FM/CP, DP via IM) — passive (no active components on rack itself)
Mounting
35 mm Top-Hat DIN Rail (Adapter included) or Direct Screw Mount (M6 bolts — holes in rear panel)
Dimensions (W × H × D)
~482.6 mm (19" rack width) × 147 mm (3U) × ~147 mm (depth varies — ~147 mm typical for UR2)
Material / Finish
Sheet Steel, RAL 7035 (Light Grey)
Grounding / Shielding
Integrated ground strap to cabinet; rear-panel earth stud
18-Slot UR2 Flexibility: Supports a single CPU with up to ~16 I/O/FM/CP modules centrally, or can be partitioned with Interface Modules (IM 460/461) to create a CR (Central Rack) + ER (Expansion Rack) in a multi-rack S7-400 system.
Standard 19" Width: Fits directly into control cabinet 19" uprights — no adapter plate needed.
Passive Backplane: No active electronics — reliability determined solely by inserted modules; bus continuity is factory-tested.
Future-Proof S7-400 Platform: Compatible with all current S7-400 CPUs and I/O modules — a single rack type covers most project sizes before needing ER/Distributed I/O.
Applications
Central Control Rack: Hosting CPU, PS, analog/digital I/O, and communication processors for a medium-complexity process cell or machine line.
Multi-Rack S7-400 Systems: Used as Central Rack (CR) with Interface Modules linking to Expansion Racks (ER1/ER2 via IM 460-1/461-1 or IM 470-1/471-1 over fiber or copper).
Retrofit / Brownfield: Replacement rack for aging S5 or early S7-400 installations — same footprint and slot numbering conventions.
Test / FAT Benches: Building a representative S7-400 configuration for factory acceptance testing prior to site commissioning.
Note: For smaller S7-400 racks, see UR1 (9 slots — 6ES7400-1TA11-0AA0). For redundant H-systems, both CPUs occupy slots in the same UR2 or separate UR2s with synchronization modules. The PS 407 power supply (e.g., 6ES7407-0KA02-0AA0 for 10A 120/230V AC) and CPU must be ordered separately. Slot 1 is reserved for PS 407; Slot 2 is the default CPU slot in a central configuration.
