In the elevator industry, this relay is a critical \"Safety Integrity\" component, specifically designed so that the Normally Open (NO) and Normally Closed (NC) contacts are mechanically linked. This ensures that if one contact welds, the others cannot move, allowing the controller to detect a hardware failure.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eCore Specifications\u003c\/b\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003eManufacturer:\u003c\/b\u003e Schrack (TE Connectivity)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003ePart Number:\u003c\/b\u003e V23050-A1110-A533\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003eRelay Type:\u003c\/b\u003e Force-Guided \/ Linked Contacts\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003eCoil Voltage:\u003c\/b\u003e 110V DC\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003eContact Configuration:\u003c\/b\u003e 6-Pole (3 NO \/ 3 NC)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003eContact Rating:\u003c\/b\u003e 8A @ 250V AC\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003eCoil Resistance:\u003c\/b\u003e Approx. \u003cspan class=\"math-inline\"\u003e$10,080 \\Omega$\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003eMounting:\u003c\/b\u003e PCB (Through-hole) or Socket-mount\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003chr\u003e\n\u003ch3\u003e\u003cb\u003eElevator Logic\u003c\/b\u003e\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003eSafety Circuit Monitoring:\u003c\/b\u003e Used to monitor the state of the safety string (emergency stops, final limits, and pit switches) to provide a redundant signal to the microprocessor.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003eRedundant Brake Control:\u003c\/b\u003e Frequently employed in the brake monitoring circuit.
