Description
REF542PLUS 1VCR007346
The REF 542plus feeder terminal is a compact digital bay control technology solution. It can be used in several different medium voltage applications, such as in feeder protection, transformer protection and motor protection.
The feeder terminal REF 542plus, like its predecessor REF 542, combines measurement, monitoring, protection, control and self diagnostics in one package. With its integrated communication protocols, the REF 542plus can be easily incorporated into any substation automation system from ABB or third parties.
These new generation devices provide exceptional flexibility and scale-ability resulting in smart and clean solutions compared to more traditional approaches. The software solution allows you to use the REF 542plus in all ABB primary air and gas insulated switchgear solutions.

It also has many counters and timers, which are beyond the reach of relay circuits. Small box or module, its internal timer and counter can reach hundreds or thousands. This is also because only one word in the memory plus some flag bits can become a timer and a counter, so there are so many.
In addition, these internal devices can also be set to maintain or not maintain after power loss, that is, reset after power on. To meet different use requirements. These are also difficult for relay components.
Its data storage area can also be used to store a large amount of data, hundreds, thousands, and tens of thousands of words of information can be stored, and it will not be lost after power failure.
PLC also has abundant external equipment, which can establish friendly human-computer interface for information exchange. Can enter program, input data, can read program, read data. In addition, reading and writing can be carried out on the screen with pictures and texts. After reading the data, it can be dumped and printed. Data input can be keyed in, read and card in, and so on.
The PLC also has a communication interface, which can be linked or networked with the computer to exchange information with the computer. It can also be networked to form a larger and wider control system than a single machine.
The PLC also has a powerful self-test function for self-diagnosis. The results can be recorded automatically. This makes its maintenance more transparent and convenient.
The rich functions provide the possibility for the wide application of PLC; At the same time, it also creates conditions for the automation, telecontrol and intelligent control of industrial systems.
PLC, which integrates rich functions, is not available in other electric controllers; It is incomparable with traditional relay control circuit.
