Product Description

Lifecycle Status:

The Harmony RM22-TU relay is a modular multi-function 3-phase control relay that offers comprehensive monitoring capabilities for electrical values in various industrial and building control panels.

It is suitable for a wide range of automation applications such as hoisting, packaging, lifts, textile, and water systems. Its compact form-factor with a width of 22.5mm allows for flexible installation on DIN rail, occupying the same space as any modular 1-pole DIN device.

This relay comes equipped with a diagnostic button and a sealable cover for easy access and maintenance. It also features simple and precise settings using screw trimmers, ensuring efficient operation in automated systems.

The Harmony RM22-TU relay provides automatic shutdown management and fault information to the user, enabling quick identification and troubleshooting of any issues that may arise.

This multi-function controller is an ideal choice for hard-wired logic automated systems, making it perfect for refurbishing old installations without the need for a PLC.
