The TELE K3UM24VDC02 is a DC voltage monitoring relay designed for reliable supervision of 24V DC systems. It offers two selectable monitoring modes: undervoltage and window monitoring, ensuring flexible protection depending on application needs.

The relay features adjustable threshold values—minimum between 75–125% and maximum between 80–130% of the nominal voltage—along with configurable hysteresis for accurate response to voltage deviations. Equipped with two changeover contacts (250V AC, 5A), the K3UM24VDC02 ensures dependable switching performance. It is housed in a compact 38mm plug-in enclosure for 11-pin socket mounting, making it easy to install in various control setups.

LED indicators provide clear status updates: a green LED signals supply voltage presence, red indicates a fault condition, and yellow shows the output relay state. Robust and precise, the K3UM24VDC02 is ideal for protecting sensitive equipment in low-voltage DC applications.
