Monitoring Relays
A Monitoring Relay is a protective control device. The basic functions are to receive input signals, monitor and determine them, and output an alarm signal if a set value (threshold) is reached. Monitoring Relays monitor power supplies (voltage, current, power, phase), temperatures, and other analog signals and detects abnormalities in machines and equipment by determining values against alarm thresholds.

Frequency Sensing Relay
This relay is a frequency monitoring relay with four stages of adjustable frequency pick up & drop out points. Each frequency set point can be set for under or over frequency operation & has an independent time delay driving an output relay. An undervoltage lockout is used to disable the four frequency outputs when the voltage falls below a preset level. Each of the four setting stages has a rate of change of frequency (ROCOF) element with an independent time delay.
