Harmony Control. This mains frequency monitoring relay is used to monitor frequency fluctuations in alternating current networks 120-277 VAC with 50 Hz or 60 Hz. A separate limit value is set for the undershoot and overshoot and each is output via an output with a relay changer. An error memory can be set and holds the error message until a reset.
