Fast Global Shipping ensures minimal disruption to your production schedule.

Backed by Siemens’ proven engineering heritage, this rack is the preferred choice for engineers in Oil & Gas, Power Generation, Pharmaceutical, and Automotive sectors. Contact us today to confirm availability and lead time.

Typical Application Scenarios

✅ Oil & Gas Upstream & Downstream
Offshore platforms and onshore refineries demand ATEX/IECEx-certified hardware that survives corrosive atmospheres and extreme vibration. The UR2-H rack’s H-system compatibility enables fully redundant S7-400 PLC System configurations, eliminating single points of failure in pipeline control and emergency shutdown systems.

Power Generation & Grid Management
Turbine governors, generator excitation systems, and substation automation require deterministic scan times and high I/O density. The 18-slot architecture of the 6ES7400-0HR02-4AB0 accommodates extensive analog and digital I/O alongside communication processors for seamless SCADA integration.

✅ Pharmaceutical Batch Manufacturing
FDA 21 CFR Part 11 and GMP compliance demand audit-ready, high-availability control platforms. Redundant CPU and power supply slots within this rack support continuous batch operations with zero unplanned interruptions.

✅ Automotive Body & Paint Shop Automation
Multi-robot welding lines and paint booth conveyors require coordinated, high-speed I/O processing. The scalable rack architecture — expandable to 21 racks via interface modules — supports plant-wide Industrial Automation without architectural redesign.

✅ Water & Wastewater Infrastructure
Municipal pumping stations and chemical dosing systems benefit from the rack’s robust EMC shielding and wide operating temperature range, ensuring reliable operation in electrically noisy, humid environments.

Core Features & Technical Advantages

• 18-Slot Capacity — Accommodates CPUs, power supplies, I/O Signal Modules, Communication Processors, and Function Modules in a single robust enclosure
• H-System (High-Availability) Compatible — Supports dual-CPU redundant configurations for zero-downtime process control; a defining advantage over standard UR2 racks
• Precision Aluminum Backplane — Integrated K-bus (communication) and P-bus (power distribution) deliver reliable, low-impedance signal integrity across all 18 slots
• Heavy-Duty Industrial Construction — Rated for operating temperatures 0°C to +60°C, vibration per IEC 60068-2-6, and shock per IEC 60068-2-27; built for harsh plant environments
• Global Safety Certifications — CE, UL 508, cULus, FM Class I Div 2, ATEX Zone 2, IECEx; compliant for worldwide deployment including hazardous areas
• Scalable Expansion Architecture — Extend to up to 21 racks (378 total slots) via IM 460/461 interface modules for enterprise-scale Industrial Automation
