Omron K8DT-LS Series Monitoring Relay, 3-Phase Electrical, 0.1to10s Time Delay - K8DT-LS1TD

This monitoring relay is designed to supervise three-phase supplies and detect overvoltage and undervoltage conditions within industrial control panels. It operates on a wide 20.4-26.4V AC/DC supply and is intended for DIN-rail installation in machinery, automation and electrical distribution systems where timely phase supervision and adjustable response are required.

Features and Benefits:

• SPST contact simplifies integration with control circuits and alarms
• Time delay adjustable 0.1-10s to prevent nuisance tripping
• Low power consumption at 1.8VA reduces panel load
• Push-in terminals enable Rapid wiring and secure connections
• IP20 enclosure suitable for protected control panels
• Wide ambient rating from -20 to 60°C for varied environments

Applications

• Suitable for phase-loss detection on industrial motors
• Ideal for three-phase supply supervision in control panels
• Used with contactors to prevent motor re-energisation after faults
• Can be used for protective monitoring in production lines
• Used for plant maintenance systems requiring adjustable response times

What type of electrical phase does it monitor and why is that important?

It monitors three-phase systems, allowing detection of phase loss or imbalance critical to motor protection and preventing mechanical damage.

How is the device mounted within control equipment?

It clips onto a standard DIN rail for straightforward panel installation and space-efficient arrangement.

Which approval standards does it conform to for industrial use?

It meets recognised standards including EN61326-1, UL31010-1, EN61010-1 and RoHS for electrical safety and electromagnetic compatibility.

What Terminal style does it use and what benefit does that provide during wiring?

It uses push-in terminals that provide quick insertion and firm retention of conductors, reducing installation time.

What environmental temperatures can it tolerate during operation?

It is rated to operate between -20°C and 60°C, allowing use in both cool and warm industrial settings.
