PLCs, Power Supplies & Others

The Honeywell 900R08R-0101 functions as an 8-slot redundant power supply extension rack for Series 900 control systems. This chassis houses I/O modules and provides dual redundant power for maximum system availability. You can deploy this rack in critical applications requiring uninterrupted operation.

Technical Specifications

High-Availability Architecture

The 900R08R-0101 features 2 dedicated power supply slots supporting 1+1 redundant operation. Both power supplies share the load during normal operation. If one supply fails, the other immediately assumes full load with <10 ms failover time. You therefore experience no process interruption during power supply maintenance or failure.

8 I/O module slots accommodate various analog, digital, and specialty modules. The segmented backplane supports hot-swapping of modules without disturbing other I/O. You can replace failed modules while the system continues operating.

Flexible Power Options

This extension rack accepts either 110/220 VAC or 24 VDC power inputs through field-selectable power supplies. You can therefore match existing plant power distribution systems. The redundant configuration accepts mixed supply types for added flexibility.

The backplane delivers 10 A at 5 VDC and 5 A at 24 VDC to installed modules. This capacity supports fully loaded racks with power-hungry modules. Convection cooling with no moving parts ensures silent, maintenance-free operation.

Seamless System Integration

The Honeywell 900R08R-0101 connects to control processors via PROFIBUS DP or ControlNet through optional gateway modules. This communication links remote I/O to the main controller for coordinated automation. LED indicators display power supply status and module health at a glance.

This rack integrates directly with Honeywell Series 900 and Experion platforms. You can therefore expand I/O capacity while maintaining a single control architecture.

Rugged Mechanical Construction

Measuring 280 mm x 480 mm x 150 mm and weighing 8.2 kg, the 900R08R-0101 mounts on DIN rail or directly on panels. The powder-coated steel enclosure withstands industrial environments. IP20 protection prevents accidental contact with internal components.

Pre-drilled mounting holes accept standard fasteners for secure attachment. The rack ships fully assembled with backplane and mechanical guides for module installation.

Environmental Specifications

This extension rack operates reliably in 0°C to +60°C environments suitable for most industrial facilities. The -40°C to +85°C storage range allows safe transport and inventory management. 5% to 95% non-condensing humidity tolerance ensures dependable performance in varying conditions.

ATEX Zone 2 and IECEx approvals permit installation in hazardous areas with occasional explosive atmospheres. With CE, UL, and CSA certifications, this rack meets global standards for industrial control equipment.
