Omron MK3P-I Relay

The Omron MK3P-I is a 3PDT general-purpose power relay with an 11-pin PF113A socket base, designed for reliable electromechanical switching in industrial control systems. It uses a 24 VAC coil (50/60 Hz) and can switch loads such as motors, solenoids, contactors, and signaling devices, making it suitable for motor control circuits and automated machinery. Common installations include control panels, conveyors, packaging equipment, HVAC systems, and process automation lines where dependable AC and DC load switching is required. Electrical specifications include a 10 A resistive rating at 250 VAC, 7 A general use at 250 VAC, and 10 A at 28 VDC, with a maximum switching voltage of 250 VAC / 250 VDC and a maximum switching current of 10 A; contact material is silver alloy. The relay offers a mechanical life of at least 10,000,000 operations and an electrical life of at least 100,000 operations, with operate and release times capped at 20 ms (AC coil). It mounts via plug-in with a PF113A socket base and operates from -10°C to +40°C. For replacements, common options include Omron MK3P-I AC24, MK3PN-I AC24, and MKS3P-5 24VAC.
