Omron 3 Phase Monitoring Relay SPST Contact DIN Rail Mount 20.4-26.4 V dc 26.4 V ac K8DT-LS1TD

Omron K8DT-LS1TD Monitoring Relay is a high-precision device designed for supervising three-phase electrical supplies in industrial and automation control panels. It features a compact DIN rail mount form factor with IP20 enclosure, making it suitable for installation in protected environments requiring reliable phase monitoring.

This model utilizes a SPST contact configuration to simplify integration with control circuits and alarms, and it offers an adjustable time delay setting from 0.1 to 10 seconds to minimize false trips caused by transient fluctuations. The device supports both DC (20.4 to 26.4 V) and AC (26.4 V) supply voltages with a very low power consumption of 1.8 VA, ensuring minimal impact on panel load.

The push-in terminal design facilitates rapid wiring with secure connections, improving installation efficiency and reducing maintenance time. With a wide ambient operating temperature range from -20°C to 60°C, the relay is capable of operating reliably across diverse industrial conditions.

Typical applications include phase loss detection on industrial motors, three-phase supply supervision in control panels, protective monitoring in manufacturing lines, and plant maintenance systems requiring adjustable response times. The relay helps prevent motor re-energisation after faults by integration with contactors, thus enhancing equipment safety and longevity.

The K8DT-LS1TD meets international safety and electromagnetic compatibility standards, including EN 61326-1, UL 31010-1, EN 61010-1, and RoHS compliance, ensuring trustworthy use in various industrial sectors such as manufacturing, electrical distribution, and automation.

Monitors three-phase power supply for voltage irregularities. Adjustable time delay from 0.1 to 10 seconds prevents nuisance tripping. Operates on 20.4 to 26.4 V DC and 26.4 V AC supply voltages. Low power consumption of 1.8 VA reduces panel energy load.

Push-in terminal design allows quick and secure wiring. Compact DIN rail mount with dimensions 90mm x 90mm x 17.5mm. IP20 rated enclosure suitable for protected control panels. Wide operating temperature range of -20 to 60°C for diverse industrial environments.
