Description

This Harmony RM22TA asymmetry control relay allows monitoring of power supply circuits in 3-phase networks. This modular 3-phase 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 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. 0 0 0 0 0 0 0 0 0 0 0 0
