This Harmony RM17-UB relay allows monitoring of voltage control in 3-phase networks. This modular multi function 3-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 slimmest form-factors with 17.5mm 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 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.
