The SS-23 static time relay is a new type of digital time relay designed and manufactured using crystal oscillator, frequency division, and counting principles. It is used in relay protection systems, especially in situations where accurate delay and shortened coordination level are required, as well as industrial control and program control that require low power consumption and a large setting range.
