Omron PCB Relay 24V AC Coil 10A 3PDT Plug-In, Mechanical Indicator, MKS3PI-5 24VAC

The Omron MKS3PI-5 24VAC is a high-quality, general-purpose PCB relay designed for use in industrial automation, control systems, and electrical panels. Featuring a 24V AC coil with a 3PDT (three-pole, double-throw) contact configuration, this relay is engineered to provide reliable circuit control in a wide range of industrial and commercial environments. Its plug-in, PCB-mount construction ensures both ease of installation and secure long-term operation.

With a switching current capacity of up to 10A and support for both AC and DC loads up to 250V, this relay handles medium power switching needs effectively - making it suitable for use in motor control panels, signaling equipment, and relay logic circuits. The mechanical indicator on the relay body enables operators and maintenance staff to instantly verify the operational state of the relay, providing essential feedback during installation, commissioning, or routine checks.

Built for versatility and durability, the Omron MKS3PI-5 24VAC is RoHS compliant and is constructed with silver alloy contacts for low resistance, high conductivity, and long life. Its coil resistance is precisely engineered at 48.4 Ω for efficient power use and dependable actuation. The relay operates efficiently across a broad ambient temperature range from -40°C to +60°C, ensuring stable performance even in demanding industrial and laboratory settings.

The relay's compact 34.5 x 34.5 x 53.3 mm form factor fits well in densely populated PCB layouts, maximizing space efficiency in control panels and machinery. Its plug-in terminal interface is compatible with standard relay sockets, simplifying replacement and reducing maintenance downtime. Additional features include a built-in mechanical indicator and a lockable test button on all MKS series units, enhancing operational flexibility and verification during testing protocols.

Applications of the MKS3PI-5 24VAC include use in automation systems for switching control circuits, electrical panels for equipment management, relay sequence logic in machine automation, and as a general main or signal relay in process control systems, HVAC installations, and commercial or laboratory electrical racks. Regular inspection and maintenance of the installed relay - ensuring the wiring and operating temperature remain within specified limits - will maximize reliability and operational safety.

This product is essential for engineers designing circuit control for manufacturing plants, building management systems, or laboratory automation, where robust, high-quality relays with mechanical status indicators help ensure both circuit integrity and easy troubleshooting. As part of Omron's MKS family, the relay upholds a tradition of reliable performance and high build quality, making it a secure choice for industrial applications and automation projects.
