Schneider Electric - Optimise equipment efficiency and availability with Harmony Relays


The Harmony relay range includes a wide range of electromechanical relays, guard relays and time relays that can be obtained pre-assembled. The range is designed to be perfectly and easily mounted in control cabinets and electrical panels. Harmony relays are designed with the highest certification which is ideal for demanding applications.

Harmony electromechanical relays

Harmony's electromechanical relays include a whole range of narrow interface, miniature, universal and high-power relays, from 1 CO to 4 CO contacts, up to 30 A. The relay bases are space-saving and suitable for both DIN rail and panel mounting. Harmony relays are also available pre-assembled, only one reference needed, saving time during selection and installation.


Harmony monitoring relays

The monitoring relays monitor and detect special / unexpected operating conditions related to phase, current, voltage, fluid level, frequency, speed, temperature and pump control. They feature a memory function and integrated LED to indicate control status. In case of fault detection, the relays will automatically switch off so that the end user can take necessary measures before serious and costly failures occur/occur.


Harmony time relays

Harmony time relays time events in industrial automation systems by closing and opening contacts before, during or after a specified period of time. They are designed for wired logic automation systems that complement the functions of PLCs. The time relays are suitable for various applications such as machinery, buildings, water treatment and HVAC.
