"This Harmony RM17-U control relay allows monitoring of overvoltage control." "This modular control relay is ideal for monitoring of electrical values and voltage variation 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 selectable memory function, integral LED for indicating control status, sealable cover, with 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."
