Omron Relay Base 14pin

Description

Omron LY4N-J 14-Pin Miniature Power Relay (4PDT – High Capacity) The Omron LY4N-J is a high-capacity, heavy-duty miniature electromagnetic power relay designed for demanding industrial automation panels and heavy machinery control setups. Featuring a 14-pin terminal layout, this 4PDT (4 Pole Double Throw) relay allows a single control input to safely toggle up to four separate high-amperage electrical pathways simultaneously. While it shares a similar 14-pin footprint with the standard MY4 series, the LY4 family is physically larger and engineered with beefier contacts to handle double the switching current. Key Features Contact Configuration: 4PDT (4 Form C: 4 Normally Open / 4 Normally Closed contacts). High Switching Capacity: Upgraded heavy-duty capability, confidently handling loads up to 10A at 240V AC or 10A at 28V DC (compared to the standard 3A–5A ratings of the MY4 series). Visual Diagnostics: Outfitted with an integrated LED status indicator lamp within a transparent “ice-cube” protective shell, providing instant verification when the control coil is energized. 14-Pin Layout: Comprises 2 pins for the triggering solenoid coil, 4 common (COM) lines, 4 normally open (NO) contacts, and 4 normally closed (NC) contacts. Heavy Blade Pins: Uses wider, robust flat blade plug-in terminals engineered to manage high current distribution safely without overheating. Compatibility Guide The LY4N-J is universally relied upon in heavy industrial applications where the space-saving footprint of a plug-in relay is needed, but the current demands match those of a small contactor block. 1. Compatible Control Voltages (Coil Types) While the physical chassis across the LY4 series remains uniform, your triggering line voltage must align perfectly with the specific coil rating stamped on the relay: AC 220V / AC 240V Coils: Engineered to plug directly into standard plant utility grids, facility mains lines, and direct line-voltage safety sequence loops. DC 24V / DC 12V Coils: Optimized for low-voltage integration with industrial sensor arrays, safety circuits, and digital output modules on Programmable Logic Controllers (PLCs). AC 110V / AC 120V Coils: Frequently found in manufacturing plants, marine control consoles, and legacy automation networks. 2. Compatible Base Sockets (Mounting) Because the flat blade terminals on this high-capacity model are significantly wider than standard miniature relays, it cannot use standard MY4 sockets. It requires its own dedicated high-capacity base: PTF14A / PTF14A-E Sockets: The standard matching 14-pin high-capacity screw-terminal tracking base. It snaps directly onto a standard 35mm DIN rail, giving field technicians a rugged block to secure heavy, thick raw panel wiring with a standard screwdriver. 3. Common Applications Multi-Phase Motor & Pump Control: Directly switches or isolates small three-phase motors, industrial fluid pumps, heavy exhaust blowers, and air compressor systems. High-Inductive Load Isolation: Acts as a rugged sacrificial barrier to absorb the heavy electrical arc flashes produced by large solenoids, heating blocks, or heavy contactors, thereby protecting delicate upstream logic cards. Complex Multi-Circuit Interlocking: Instantly distributes a single system trigger (such as an emergency stop or safety gate trip) to isolate four completely independent high-current power lines at the same time.
