Information
This Harmony RM35-HZ control relay allows monitoring of frequency control. This modular control relay is ideal for monitoring of frequency variations in electrical power sources such as wind turbine and micro-power stations. It has one of market medium form-factors with 35mm width, allowing for a flexible and easy installation on DIN rail, using the same space as any modular 3-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 an automatic detection of abnormal electrical values before they incur serious damage to machinery thus reducing your maintenance and downtime costs. Multi function controller for wide choice selected in hard-wired logic automated systems, ideal for refurbishment of old installations without using a PLC.
