Omron LY4N Series Power Relay, 120V Coil Voltage, 4PDT Contact Configuration - LY4N 110/120VAC


This power relay is a Compact electromechanical switching device designed for control and signalling tasks in industrial and electronic systems. It operates on an alternating Coil supply and provides multiple changeover contact paths for complex switching arrangements, suitable for PCB mounting in automation and electrical assemblies.

Features and Benefits:


• 120V AC Coil consumes 2.5W for predictable drive requirements
• Coil resistance 1800Ω reduces Coil current draw for efficiency
• Four-pole double-throw contact configuration enables complex switching
• Silver alloy contacts deliver low contact resistance of 50mΩ for minimal voltage drop
• Rated switching current 10A supports moderate power loads
• PCB Terminal format simplifies integration onto printed circuit boards

Applications


• Suitable for motor control logic in automated machinery
• Ideal for relay-based sequencing in control panels
• Used for signal routing in industrial instrumentation
• Can be used for switching DC loads up to 125V in control circuits
• Used with PCB-mounted assemblies in electrical equipment

What ambient temperature range can it withstand during operation?


It operates within a -25°C to 55°C ambient range suitable for typical indoor industrial environments.

Which voltages can be switched by the contacts in AC and DC systems?


The contacts are rated to switch up to 125V in both AC and DC applications.

How is the relay packaged for PCB use and what connection type does it require?


It uses PCB terminals allowing through‑hole mounting directly onto printed circuit boards.

What approvals indicate suitability for industrial deployment?


It carries recognised CSA and UL approvals indicating compliance with established safety standards.

Approvals

VDE, UL, CSA, TUV
