Omron LY4-AC24 Relay
The Omron LY4-AC24 Relay is a heavy-duty, 4PDT (4-Pole Double Throw) power relay engineered for reliable switching in demanding HVACR and industrial control panels. Operating on a 24Vac coil, this 10Amp general-purpose relay is designed to handle multi-circuit control with high efficiency. Its compact "ice cube" footprint features plug-in/solder terminals, making it compatible with standard PTF14A-E sockets or direct-wired applications. This model is equipped with an integrated arc barrier to prevent cross-phase arcing, a critical feature when managing inductive loads in motor starters or large solenoid assemblies. The silver alloy contacts ensure low contact resistance and long-term electrical durability, maintaining circuit integrity under continuous operation. For technicians looking for a 24V AC power relay that meets UL, CSA, and VDE standards, the Omron LY series remains the industry standard for electromechanical relay replacements in control logic and energy management systems. Its standard bracket mounting facilitates secure installation in high-vibration environments.
Key Benefits- High Switching Capacity: Features a 10A contact rating capable of managing multiple loads across its 4PDT configuration.
- Enhanced Arc Suppression: Built-in arc barriers effectively isolate contacts to prevent short circuits between poles during high-voltage switching.
- Versatile Termination: Utilizes 14-pin plug-in/solder terminals for rapid deployment in relay sockets or custom PCB integration.
- Robust Construction: Dielectric strength of 2,000V ensures safety and performance stability in industrial power-switching scenarios.
What is the primary application for a 4PDT 24VAC relay in HVAC systems?
Contractors typically use the Omron LY4-AC24 for interlocking control circuits, sequence-of-operation logic, and switching multiple independent fans or dampers from a single 24Vac control signal.
Can the LY4-AC24 replace an LY4N-AC24 model?
Yes, the LY4-AC24 is the standard version. The "N" suffix indicates a built-in LED indicator. They are pin-compatible and share the same 24Vac coil and 10Amp specifications, though the standard model lacks the visual status light.
Is this relay suitable for DC loads?
While the coil is designed for 24V AC operation, the contacts are rated for both AC and DC loads (typically up to 30Vdc at 10A). Always verify the specific resistive or inductive derating curves for your DC application.
