Overview
The Allen-Bradley 800H-JRN5 /G is a 30mm selector switch base for the Bulletin 800H industrial control family. This base unit serves as the mechanical foundation for selector switch operators, designed for three-position selection in manual control, mode switching, and equipment sequencing applications. As part of the robust 800H platform, it delivers the reliability and durability required in factory floor, water treatment, power generation, and processing plant environments.
Key Features
- 30mm industry-standard form factor for integration with existing 800H control stations
- 3-position capability for mode or selector applications
- Compact base design minimizes footprint while supporting full operator interface
- Compatible with standard 800H cam blocks and contact modules
- Rated for industrial environments including hazardous locations (Class I, Div. 2)
- Drop-in replacement in 800H-compatible panels and stations
Technical Specifications
The 800H-JRN5 operates within the electrical and mechanical parameters of the 800H family. Standard contact block configurations support low-voltage logic circuits and control applications. The base accepts standard D018 cam keys and cam blocks from the 800H selector switch line.
- Operating Temperature: -40°C to +60°C (per 800H standard)
- Mechanical Life: 1,000,000+ cycles
- Positions: 3-position selector configuration
- Size: 30mm diameter standard opening
- Material: Die-cast aluminum construction with corrosion-resistant treatment
Typical Applications
- Mode selection switches (Auto/Off/Manual operation)
- Equipment start/stop/neutral selector controls
- Pump or motor lead/lag selection
- Process flow direction or bypass selectors
- Hazardous location manual switchover controls
