Voltage relay with display

Display

— usually, the simplest segmental LCD displays are installed in the control relays, capable of displaying numbers and some special characters. This screen has two main functions. Firstly, during operation, it displays key network parameters — voltage, current and/or power, as well as notifications of problems; some models provide several separate displays, each for its own parameter. Secondly, the screen is used when changing device settings.
