100S-D180EA22BC Allen Bradley

The 100S-D180EA22BC is an Allen-Bradley 100S-D Series Safety Contactor. It is a device specifically designed for use in safety-critical applications, typically as part of a machine safety circuit, to safely switch and isolate power to equipment like motors.

Key features of this series include:

• Mechanically Linked/Captured Contacts (Per IEC 60947-5-1 Annex L): This design is critical for safety applications, as it ensures that if a main power contact welds closed (fails to open), the auxiliary monitoring contact will not signal that the contactor has opened.
• Mirror Contacts (Per IEC 60947-4-1 Annex F): These auxiliary contacts are used in the monitoring circuit of the safety system.

⚙️ Product Parameters (Typical Specifications for 100S-D180EA22BC)

(Note: The exact coil voltage and auxiliary contact configuration are essential for ordering. “EA22BC” codes a specific configuration—”EA” for the coil voltage and “22” for the auxiliary contact arrangement.)

➕ Product Advantages

• Enhanced Safety Reliability: The mechanically linked and mirror contact design provides highly reliable feedback to the safety monitoring system, making it suitable for applications up to Performance Level e (PLe) and Safety Integrity Level 3 (SIL 3).
• High Performance: Capable of handling a substantial $180 \text{ A}$ load, suitable for large motor control.
• Space Saving: Often designed with a compact footprint relative to its current rating.
• Global Compliance: Conforms to major international standards, simplifying use in global applications.
• Electronic Coil: Provides a wider operating voltage range and typically lower holding power consumption compared to standard AC coils, reducing heat generation.

⚠️ Important Considerations (Precautions)

• Safety Circuit Integration: This contactor must be used with a compatible safety monitoring device (like a safety relay or safety PLC) that checks the status of the mirror contacts to ensure the contactor has opened safely.
• Correct Wiring: The auxiliary contacts (especially the mirror contacts) must be wired correctly into the safety circuit monitoring loop for the safety function to be effective.
• Coil Voltage: Verify that the specified control voltage (coded by “EA” in the part number) matches your control power supply.
• Load Type: Ensure the $AC-3$ rating is appropriate for your motor load (AC-3 is standard for starting and switching off squirrel-cage motors).

🏭 Product Applications

The 100S-D series safety contactors are primarily used in Emergency Stop (E-Stop) and Guard Interlock circuits for machinery that requires a high degree of operational safety.

• Motor Control for Safety Shut-down: Safely isolating power to large motors on machines like conveyors, mixers, pumps, or machine tools.
• Emergency Stop Systems: Used as the final switching element to immediately remove power from a hazardous movement when an E-Stop button is pressed.
• Guard Door Monitoring: Isolating power when a safety guard or gate is opened, ensuring the machine cannot start or continues to run in a dangerous state.
