The AZ2100-1A-24DF is a miniature power relay designed for industrial switching applications with a 1 Form A (SPST-N.O.) contact arrangement and 24 VDC nominal coil voltage. It features a maximum switched power rating of 900 W or 10,000 VA with 40 A switching capability on Form A contacts, and operates over a temperature range of -55°C to 85°C (Class B coil). The relay offers a life expectancy of 10 million mechanical operations and 100,000 electrical operations at 240 VAC, with both PCB and quick-connect terminals for flexible installation. Its compact dimensions (32.23 mm × 27.4 mm × 27.9 mm), low initial contact resistance of =50 mO, and UL/CUR approval make it suitable for HVAC controls, industrial automation, and refrigeration applications requiring reliable high-current switching.
