Compact 3-Phase Monitoring Relay for Motor Protection and Phase Sequencing
The Omron K8DS-PM2 is a compact, high-performance 3-phase 3-wire monitoring relay designed to protect motors and critical equipment from damaging electrical faults. This protective relay continuously monitors phase sequence (reverse phase) and detects phase loss (open phase) in AC power systems, providing reliable protection against incorrect wiring, power supply failures, and phase imbalances. With its miniature design and 1c (SPDT) output contact, the K8DS-PM2 is ideal for integration into control panels, motor starter circuits, and machinery where space is limited. It operates on a wide-range AC/DC power source for versatile installation and features a clear LED indicator for operational status. Engineered for industrial automation, HVAC systems, pumps, compressors, and conveyor systems, this monitoring relay helps prevent equipment damage, reduce downtime, and enhance operational safety by ensuring correct phase rotation and presence.
