The Omron LY4N General Purpose Relay, sold as a 10-pack with a 120 VAC coil, is an industrial plug-in relay for control panels and automation systems. It uses a 4PDT (4 Form C) contact configuration with a 10 A switching rating and supports voltages up to 250 VAC or 125 VDC. The coil operates at 110–120 VAC and draws about 2–2.5 W, with silver-alloy contacts and a plug-in / socket mount (14-pin) terminal configuration. Designed for industrial switching and control circuits, the LY4N is suitable for control panels, machine automation, HVAC systems, and related applications, and supports socket or panel-mount installations.
