Omron LY4-AC120 Relay
The Omron LY4-AC120 is a heavy-duty 4PDT power relay engineered for demanding industrial HVACR applications and control panels requiring high switching capacity. Operating on a 120VAC coil voltage, this general-purpose relay features a 10A contact rating capable of handling inductive and resistive loads across four poles. The plug-in/solder terminal design provides versatile installation options, while the integrated standard bracket mounting ensures secure mechanical stability in high-vibration environments. Reliability is maintained through a robust arc barrier that prevents flashover between adjacent poles, essential for electromechanical relay longevity. Whether used for motor starting, sequencing, or auxiliary signal isolation, the Omron LY series remains the industry standard for contractors needing a dependable 120V relay replacement that fits standard PTF14A sockets or accommodates direct chassis mounting.
Key Benefits for Technicians:- High Switching Capacity: The 10 Amp 4PDT configuration allows for simultaneous control of multiple circuits, reducing the need for additional relay logic.
- Enhanced Arc Protection: Built-in arc barriers significantly reduce the risk of short-circuits during high-current switching cycles.
- Versatile Mounting: Includes a standard mounting bracket for direct attachment or can be used with compatible DIN rail sockets.
- Dielectric Strength: Delivers 2,000V insulation between coil and contacts to protect sensitive upstream control boards.
What is the difference between the LY4-AC120 and the LY4-DC24?
The primary difference is the coil voltage; the LY4-AC120 requires 120V alternating current to energize the coil, whereas the DC24 model requires 24V direct current. Always verify your control circuit voltage before installation.
Can I use this relay to replace a 2-pole or 3-pole relay in the same series?
Yes, provided the coil voltage and contact ratings match. A 4PDT relay can be wired to perform as a DPDT or 3PDT, but you must ensure the physical footprint and socket compatibility match your existing configuration.
How do I test the Omron LY4-AC120 relay for failure?
Verify the coil resistance using a multimeter to check for an open circuit. If the coil is intact, check for continuity across the NO and NC contacts while the relay is energized and de-energized to confirm the armature is moving correctly.
