Omron Relay 4-pole double-throw 4PDT General-purpose Electromechanical LY4N-J

The Omron LY4N-J is a 4-pole double-throw (4PDT) general-purpose electromechanical relay designed for robust switching and control functions in industrial automation, control panels, and machinery interfaces. It is part of Omron’s LY series of power relays, offering reliable contact performance with a plug-in socket interface for rapid installation and serviceability.

Key Characteristics

• Contact Configuration: 4PDT (four independent changeover contacts) enabling multiple circuit switching with a single coil actuation.

• Mounting Style: Plug-in relay designed for use with 14-pin relay sockets such as Omron PTFZ-14-E or push-in plus socket options.

• Coil Operation: Coil voltage-specific version (e.g., 24 VDC or AC variants); specify voltage when ordering.

• Indicator: Built-in LED operation indicator for visual status of relay activation (varies with specific J variant).

• Contact Rating: Typically up to 10 A switching capacity on resistive loads, suitable for moderate power control loads in automation circuits.

• Durability: Designed for high mechanical and electrical endurance with long lifecycle performance.

Typical Applications

• Industrial control panels and PLC output expansion

• Motor starters, solenoid control, and power switching

• Building automation and HVAC control systems

• Signal routing and multipole switching tasks

Summary
The Omron LY4N-J is a versatile, plug-in 4PDT general-purpose relay optimized for industrial control and switching applications, combining a rugged electromechanical design with easy socket-based installation and optional operation indication functionality.
