700-CF310Z Allen‑Bradley Control relay

Product Detailed Description

The Allen-Bradley 700-CF310Z is a robust IEC-style industrial control relay from the Bulletin 700-CF series, manufactured by Rockwell Automation. It is designed for reliable control circuit applications in demanding industrial environments. This 4-pole relay features 3 normally open (NO) and 1 normally closed (NC) main contacts, with a DC electronic coil rated at 24V DC (including an integrated diode for surge suppression). It supports vertical mounting and is compatible with a range of accessories, such as front- and side-mounted auxiliary contacts, timing modules, and mechanical latching attachments. The relay complies with IEC 60947-5-1 standards, ensuring high performance in automation systems for switching resistive, inductive, and motor loads. It is noted that this specific model has been discontinued by Rockwell Automation but remains available through secondary markets for legacy applications.

Product Parameters

The following table summarizes the key technical specifications for the 700-CF310Z, based on the 700-CF series datasheet.

Product Advantages

• Reliability and Durability: Mechanically linked and mirror contacts provide safety interlocking, preventing hazardous operation if contacts weld. Offers exceptional long life (15 million mechanical cycles) for reduced maintenance in harsh environments.
• Versatility: Supports AC/DC electronic and conventional coils with low power consumption (e.g., 1.7 W sealed for DC), enabling efficient integration into PLCs, contactors, and timing systems. Compatible with accessories like solid-state timers (repeat accuracy ±10%) and DC interfaces for flexible control.
• Compact and Easy Installation: DIN rail mountable with a slim 45 mm width, allowing space-efficient panel designs. Screw terminals ensure secure, vibration-resistant connections.
• High Performance: Handles demanding loads (up to 690V AC/440V DC) with fast operating times and high breaking capacity, ideal for global standards compliance (IEC, UL/CSA, NEMA).
• Cost-Effective Safety: Integrated diode in DC coil suppresses voltage spikes, extending component life and minimizing downtime.

Precautions and Notes

• Installation Precautions: Mount vertically only to ensure proper heat dissipation and operation. Use ferrules for wires with >16 strands to prevent terminal damage. Tighten screws to specified torque to avoid loose connections. Ensure minimum OFF time of 50 ms between operations to prevent contact arcing.
• Environmental Warnings: Derate current by 15% for AC-12 loads above 60°C; do not exceed +70°C ambient. Protect from excessive vibration (>5G) or shock (>30G) during operation. For DC electronic coils, limit ripple to ±15% to avoid malfunction.
• Safety Notes: Mechanically linked contacts are for supplementary protection only—do not use as sole safety device. Verify certifications for your region; products sold after September 2025 may have updated markings. If using with timing attachments, allow reset time (10…70 ms).
• General Warnings: This model is discontinued; source from authorized distributors for warranty. For non-standard conditions (e.g., altitude >2000 m), consult Rockwell Automation. Always follow lockout/tagout procedures during maintenance to prevent accidental energization.

Product Applications

The 700-CF310Z is suited for general-purpose control in industrial automation, particularly where reliable switching of control circuits is required. Typical applications include:

• Motor Control Centers: Interlocking and sequencing in contactor-based systems for pumps, fans, and conveyor motors.
• PLC and Automation Panels: As auxiliary relays for signal amplification, interposing, or logic functions in manufacturing lines.
• HVAC and Process Control: Switching solenoids, valves, and heaters in heating, ventilation, and industrial processes.
• Power Distribution: Resistive and inductive load control (e.g., AC-13/DC-13 categories) in substations or machinery.
• Safety Circuits: Integrating with emergency stops or sensors due to mirror contact design, in packaging, material handling, and assembly automation. It excels in environments requiring compliance with international standards, supporting voltages up to 690V AC for global deployments.
