Industrial 3-Phase Sequence & Voltage Monitoring Relay for Machinery Protection
The Omron K8DS-PH1 Phase Sequence Relay is a critical protection device designed to safeguard industrial motors, pumps, compressors, and other 3-phase equipment from costly damage caused by incorrect phase sequence (rotation), phase loss, or significant voltage imbalance. By continuously monitoring all three phases (L1, L2, L3), this DIN rail-mounted relay prevents machinery from starting or automatically shuts it down under fault conditions, ensuring operational safety and reliability. It features a wide operating voltage range of 200-480VAC and offers adjustable response delays to prevent nuisance tripping from transient voltage fluctuations. With a compact design, clear LED status indicators for power and relay output, and a robust SPDT output relay contact, the K8DS-PH1 is an essential component for maintaining the integrity of automation systems, HVAC equipment, and industrial machinery, helping to avoid downtime and expensive repairs.
