Relays & contactors

Relays & Contactors
Product Description:

Relays and contactors are electrical switching devices used in control panels, motor control centers (MCCs), automation cabinets, and equipment skids across pharmaceutical, biopharmaceutical, medical device, and other GMP-regulated environments.

Relays are typically used for signal-level switching and control logic, while contactors are designed for higher-current power switching, particularly for motors and large electrical loads.

Technical Specifications:

Device types:

  • Electromechanical relays

  • Solid-state relays

  • Motor contactors

Control voltages:

  • Common AC and DC control voltages (e.g., 24 VDC, 120 VAC)

Current ratings:

  • Low-current signal switching through high-current motor loads (application dependent)

Contact configurations:

  • Normally open (NO)

  • Normally closed (NC)

  • Changeover contacts

Mounting options:

  • DIN rail-mounted

  • Panel-mounted

Protection and features:

  • Auxiliary contacts

  • Overload relay integration

  • Arc suppression and contact protection

Design considerations:

  • Switching frequency and duty cycle

  • Compatibility with control systems

  • Electrical isolation and safety
