Omron LY2 24VDC Socketed Relay: Technical Guide, Applications and Installation
Ask a panel builder which components they trust after midnight when nobody is around to troubleshoot, and you will hear brands like Omron come up immediately. The LY2 24VDC Socketed Relay is a prime example of why — designed for control panels, built to keep runningat 24V DC when it matters most.
Omron’s strength lies in offering complete automation subsystems rather than isolated components. The Omron Sensor lineup complements the relay and switch range by providing the detection layer, so the entire signal chain — from physical event to control output — stays within one trusted supplier.
Omron LY2 24VDC — Product Profile
The Omron LY2 24VDC is a Socketed Relay rated at 24V DC, built to handle control panels reliably over a long service life. Key engineering features include arc barrier, compact body, wide socket compatibility, and the unit mounts via socket + din rail or pcb.
On the bench, arc barrier, compact body, wide socket compatibility stands out immediately. The 24V DC rating align with the control voltage standards used across manufacturing, building automation, and process control industries, reducing the need for additional conversion stages.

Where This Product Fits
The Omron LY2 24VDC Socketed Relay is commonly specified for the following applications:
- Control panels
- Machine automation
- Building management systems
Across these use cases, the consistent thread is a need for dependable switching over a large number of operations, often in environments where an unplanned fault would create significant disruption. The Omron LY2 24VDC is designed with exactly those conditions in mind.
The Omron LY2 24VDC is designed to be used with PF083A / PTF08A. Using a non-compatible socket model can compromise contact pressure and reduce overall service life, so always verify socket compatibility before ordering.
Practical Installation Tips
Commissioning the Omron LY2 24VDC Socketed Relay is straightforward. Snap or screw it into position on the DIN rail, connect cables at the correct terminals, and confirm polarity where applicable. During the first powered test, verify that the indicator LED (where fitted) responds correctly and that the output contacts behave as expected under a controlled test load.
For ongoing maintenance, periodically inspect for contact discolouration, check terminal screws for loosening, and look for any signs of heat stress on the housing. Catching these early avoids the much larger cost of an unplanned production stop.
Performance You Can Rely On
From a total cost of ownership perspective, the Omron LY2 24VDC Socketed Relay makes financial sense even when its purchase price is higher than alternatives. Reduced unplanned downtime, fewer replacement cycles, and lower maintenance labour costs add up to a clear advantage over the operational lifetime of a machine.
Frequently Asked Questions
What applications is the Omron LY2 24VDC designed for?
