Information
This Harmony RM22-UB relay allows monitoring of voltage control in single phase networks. This modular multi function single phase voltage control relay is ideal for monitoring of electrical values in industrial and building control panels. It applies to a wide type of industrial automation applications such as hoisting, packaging, lifts, textile, water. It has one of market slim form-factors with 22.5mm width, allowing for a flexible and easy installation on DIN rail, using the same space as any modular 1-pole DIN device. It also offers a diagnostic button, sealable cover, simple and precise settings with screw trimmers. It provides automatic shutdown management and fault information to user for a quick fault identification and troubleshooting. multi function controller for wide choice selected in hard-wired logic automated systems, ideal for refurbishment of old installations without using a PLC.
