Relay Basics 2-5 DC Power Relays | OMRON - Korea

Definition

This is a relay that performs high-voltage and high-capacity urgent shutdown of DC circuits.
These relays not only energize DC circuit but also shutdown the high voltage circuit at high speed when an error occurs.

Features

Omron's DC power switching technique contributes to space saving, noise reduction, miniaturization, and power saving, and is characterized by a safety and reliability design.

Types

Omron's DC power relays meet the diverse needs with a wide range of products of small size and high capacity.
