Overview
The Allen-Bradley 700-HN128 relay socket is a miniature 14-blade open style relay base engineered for reliable general-purpose relay applications in industrial control systems. This 700-HN128 relay socket provides a secure platform for 700-HC, 700-HT, 700-HRM, 700-HRC, and 700-HV series relays, delivering dependable switching performance in AC control circuits.
Key Features
- 14-Blade open style design with easy relay insertion and removal
- Screw terminal connections ensure stable, maintenance-friendly wiring
- Rated 10 amp at 300 VAC for standard industrial AC applications
- Compact form factor minimizes panel real estate while maintaining full functionality
- Multi-standard certification (UL, CSA, CUL, CE, CCC, KC) for global deployment
- DIN rail or panel mount flexibility for retrofit and new installations
Technical Specifications
The socket’s robust construction and proven Allen-Bradley engineering make it the preferred choice for replacement and maintenance cycles. Standard screw terminals accommodate #14–#8 AWG wire gauges, and the open style design allows field technicians to service relay elements without breaking power connections.
- Compatible with 700-HC, 700-HT, 700-HRM, 700-HRC, 700-HV relay series
- Supports both AC and general-purpose DC relay applications
- Dimensions optimized for compact control panels and distribution systems
Typical Applications
Common use cases include motor starters, HVAC interlocks, machine tool circuits, lighting controls, and process automation systems where relay-based logic remains the standard. The 700-HN128 is equally at home in legacy systems and modern hybrid control architectures that blend relay hardwired circuits with PLC/motor control logic.
Compatibility & Replacements
This socket is a direct drop-in replacement for worn or damaged 700-HN128 units in existing installations. Verify relay coil voltage (AC or DC), number of contacts, and load rating against your application circuit before ordering. Original equipment manufacturers and third-party integrators specify the 700-HN128 as the standard base for small-footprint AC control circuits.
