Comparison Novatek-Electro RN-132T vs Novatek-Electro RN-132

— Display. As a rule, control relays are equipped with simple segment LCD displays that can display numbers and some special characters. This screen performs two main functions. Firstly, during operation it displays key network parameters - voltage, power and/or power, as well as notifications of problems; Some models provide several separate displays, each with its own parameter. Secondly, the screen is used when changing device settings.

— Operation indicator. A pointer indicating the operation of a device, and often a specific mode of operation. Note that in this case we are talking about the simplest indicators - for example, in the form of an LED, which lights up green in normal mode and lights up red after the protection is triggered. The display is not considered an operation indicator, although it can perform such a function.

— Thermal protection. A safety system that turns off the device when it reaches a critical temperature. Some models also provide a shutdown when the permissible heating rate is exceeded. This function serves as additional insurance in case of malfunctions in the relay itself (for example, if the settings are lost and the device does not respond to overload), and in case of fire (in case of fire, the equipment must be de-energized).

— Memory of emergency operations....The function of saving data on the state of the network during emergencies. Allows you to assess the situation of what happened after resuming work.
