Product Detailed Description

Allen-Bradley relays, part of Rockwell Automation’s industrial automation portfolio, are electromechanical and solid-state devices designed to control electrical circuits by opening and closing contacts in response to electrical signals. They are widely used in industrial environments for switching, timing, and safety functions. The product line includes general-purpose relays (e.g., Bulletin 700-HA tube base, 700-HB square base, 700-HC miniature “ice cube” relays, 700-HK slim line), power relays (e.g., 700-HG for DC loads), timing relays (e.g., 700-HT alternating and off-delay timers), and safety relays (e.g., Guardmaster® MSR series and 700S-P control relays). These relays are engineered for reliability, with features like plug-in bases, blade-style terminals, and optional LED indicators for status monitoring. They support both AC and DC coils, with tamper-resistant covers and mechanically linked contacts in safety models to ensure compliance with global standards.

Product Parameters

Allen-Bradley relays offer a range of configurations tailored to specific needs. Key parameters vary by model but commonly include:

For precise specs, refer to the Bulletin 700 series datasheets on Rockwell Automation’s site.

Product Advantages

Allen-Bradley relays provide several key benefits that make them a preferred choice in industrial automation:

• Reliability and Durability: Built to withstand demanding environments, with long operational life (e.g., high cycle rates in solid-state models) and arc suppression features for DC switching, reducing maintenance and downtime.
• Versatility: Wide range of models for general-purpose, timing, and safety applications; plug-and-play design with quick-connect terminals simplifies installation and allows easy replacement.
• Safety Compliance: Safety relays (e.g., Guardmaster®) meet stringent global standards like ISO 13849-1, offering mechanically linked contacts and tamper-proof features to enhance worker protection in hazardous areas.
• Cost Efficiency: Lower power consumption and modular expansion (e.g., GuardLink® technology for smart diagnostics) reduce overall system costs; optional features like manual overrides and LED indicators improve troubleshooting.
• Global Compatibility: IEC and NEMA terminal options ensure seamless integration in international setups, with proven performance in high-vibration industries like automotive and elevators.

Precautions and Notes

When using Allen-Bradley relays, adhere to these guidelines to ensure safe and optimal performance:

• Installation: Mount in a dry, vibration-resistant location away from direct heat sources; use appropriate sockets and torque terminals to manufacturer specs (e.g., 7-9 in-lbs for blade terminals) to prevent loose connections.
• Electrical Safety: Verify coil and contact ratings match your circuit to avoid overloads; for safety relays, maintain dual-channel inputs for redundancy and test mechanically linked contacts regularly per ISO standards.
• Maintenance: Inspect for dust accumulation under covers; replace if contacts show wear (e.g., after 100,000 cycles); avoid exceeding temperature limits to prevent coil failure.
• Compatibility: Ensure firmware or accessories (e.g., expansion modules) are current; in high-interference environments, use surge protection on coils.
• Handling: Ground enclosures properly; for DC models with blowouts, align magnetic fields correctly during assembly. Always consult Rockwell’s user manuals for model-specific warnings, and de-energize systems before servicing.

Product Applications

Allen-Bradley relays are deployed across diverse industries for control, automation, and protection:

• Industrial Automation: Machine tools, pulp and paper processing, and OEM equipment for general switching and interposing between controllers and field devices.
• HVAC and Building Systems: Elevator controls, air conditioning units, and refrigeration for load alternating and timing functions (e.g., 700-HT series).
• Transportation and Automotive: High-vibration environments requiring robust relays for signaling and power distribution.
• Safety-Critical Systems: Emergency stops, guard interlocking, and feedback circuits in manufacturing (e.g., Guardmaster® for zone control and delayed outputs in robotics).
• Power Management: DC load switching in pumps, compressors, and high-current circuits, with expansion for complex safety architectures.

These applications leverage the relays’ flexibility to enhance productivity while prioritizing safety and efficiency.
