Description
Omron LY2N-J 8-Pin Electromagnetic Power Relay (DPDT) The Omron LY2N-J is a highly reliable, compact electromagnetic power relay widely used in electrical engineering, control panels, and automation circuitry. Operating as a DPDT (Double Pole Double Throw) switch, this 8-pin relay allows a single control signal to switch two separate electrical circuits simultaneously. The “N” designation features an integrated LED indicator lamp inside its transparent casing, providing instant visual feedback on whether the relay coil is energized. Key Features Contact Configuration: DPDT (2 Form C: 2 Normally Open / 2 Normally Closed contacts). Switching Capacity: Heavy-duty contacts rated up to 10A at 240V AC or 10A at 28V DC. Visual Diagnostics: Built-in LED indicator illuminates when the internal coil is active, significantly simplifying troubleshooting. 8-Pin Layout: Comprises 2 pins for the coil mechanism, 2 common (COM) contact pins, 2 normally open (NO) pins, and 2 normally closed (NC) pins. Terminal Design: Standard flat, plugin plug-in blades designed for secure placement inside matching control sockets. Compatibility Guide The LY2N-J operates universally across standard automated machinery, power distribution layouts, and protective industrial logic arrays. 1. Compatible Control Voltages (Coil Options) Ensure the supply voltage of your triggering circuit matches the specific coil rating printed on the relay’s clear chassis layer. The most common varieties include: AC 220V / 240V Coils (Most Common): Designed for standard industrial control transformers and mains voltage pilot circuits. DC 24V / DC 12V Coils: Ideal for direct integration with microcontrollers, Arduino projects, PLCs, and low-voltage automotive circuits. 2. Compatible Mounting Sockets Rather than soldering wires directly to the flat pins, this plug-in relay typically drops into a dedicated chassis or DIN-rail base module: PTF08A Sockets: The standard matching 8-pin screw-terminal socket base. It allows technicians to clip the layout onto a standard 35mm DIN rail and secure raw wire runs directly to the terminal screws. 3. Common Applications Industrial Automation: Serves as an intermediate interface relay to isolate low-current controller outputs from high-draw machinery components. Motor Control: Manages small single-phase fractional horsepower motors, inline ventilation blowers, and water pumps. Lighting Arrays: Switches commercial light banks, heaters, and auxiliary HVAC dampers safely on and off.
