DESCRIPTION

The 2-1618067-9 is a protective frequency relay from TE Connectivity's 20-000 Series designed to monitor and respond to frequency deviations in power systems. This relay energizes its output contacts when the frequency exceeds an adjustable set point, with independently adjustable pick-up and drop-out frequency settings featuring a maximum differential of 1%. The relay operates on 120 VAC single-phase input (±10%), supports frequency ranges of 40-500 Hz depending on the model configuration, and maintains stable operation across a temperature range of -40°C to +85°C with ±1% frequency error over temperature. It provides one set of normally open and one set of normally closed contacts rated at 5 amperes resistive at 120 VAC or 28 VDC, making it suitable for power system protection, grid monitoring, and industrial control applications where frequency stability is critical.
