Omron LY2N-J 24VDC DPDT Plug-In Relay with LED
The Omron LY2N-J is a general-purpose electrical relay designed for compatible laser machine control circuits and industrial electrical systems. It uses a 24VDC operating coil to control two independent sets of switching contacts.
Featuring a double-pole, double-throw (DPDT) contact arrangement, this relay allows a low-voltage control signal to switch connected electrical circuits. Its transparent housing provides visibility of the internal components, while the integrated LED indicator helps technicians identify when the relay coil is energized.
The standard 8-pin plug-in design allows convenient installation and replacement using a compatible relay socket, making the LY2N-J a practical replacement component for equipment requiring this specific relay configuration.
Important: Relays with similar appearances may have different coil voltages, terminal arrangements, or contact ratings. Verify the original relay specifications before ordering.

How the Relay Works
The LY2N-J uses an electromagnetic coil to operate two separate sets of electrical contacts. When the 24VDC coil is energized, the internal switching mechanism changes the position of both contact sets.
Each contact set includes:
- Common (COM): The shared connection for the switching circuit.
- Normally Closed (NC): Connected to common when the relay coil is not energized.
- Normally Open (NO): Connected to common when the relay coil is energized.
The built-in LED provides a convenient visual indication of coil energization, which can assist with troubleshooting machine control circuits.
Note: An illuminated LED does not confirm that the relay contacts are operating correctly. Contact operation and connected equipment should be tested separately when troubleshooting.
Compatibility
This relay is intended for equipment requiring an Omron LY2N-J or an approved equivalent with a 24VDC coil, DPDT contacts, and the corresponding 8-pin terminal arrangement.
The relay is designed for use with compatible LY-series relay sockets, including the PTF08A Relay Base (Rabbit Laser USA SKU 330), subject to verification of the socket and wiring configuration.
Before ordering, compare the replacement relay with your existing component:
- Manufacturer and model number
- 24VDC coil requirement
- DPDT contact arrangement
- 8-pin terminal configuration
- Electrical contact ratings
- Physical dimensions and socket fit
- Coil polarity and indicator requirements
- Wiring diagram printed on the original relay
Important: A 24VAC relay is not a direct replacement for this 24VDC model. Relays with matching dimensions may still have different electrical specifications.
Relay socket sold separately. Confirm compatibility before purchasing a replacement socket or relay.
Installation & Safety
- Turn off and disconnect the laser machine from its electrical power source before replacing the relay.
- Verify the replacement relay's coil voltage, contact ratings, and terminal arrangement.
- Inspect the relay socket for heat damage, corrosion, or loose electrical connections.
- Align the relay pins correctly with the socket before installation. Do not force the relay into place.
- Follow the terminal wiring diagram and any polarity requirements marked on the relay.
- Confirm the relay and connected control circuit operate correctly after installation.
- If a replacement relay overheats, chatters, or fails repeatedly, troubleshoot the connected circuit before installing another relay.
Safety Note: Electrical components inside a laser machine may carry hazardous voltages. Repairs should be performed by qualified personnel familiar with electrical control systems. Never bypass machine safety interlocks or protective circuits.
Rabbit Laser USA supplies replacement electrical components, relays, controllers, and parts for CO2 laser machines. If you're unsure whether the Omron LY2N-J is compatible with your equipment, contact our team with your machine model and clear photographs of the existing relay and socket.
