The E1858EL converter is designed to measure AC frequency on the basis of analogue-to-digital conversion of input signals.
The converter provides the following features: software selection of the input signal, measurement range; software selection of the range of the output analogue signal; formation of the output discrete signal when the set threshold value is reached; display on the indicator of the input signal as a percentage of the nominal value; data transmission via RS485 interface (Modbus RTU protocol); production of converters without RS485 interface or analogue output.
The possibility of programme selection of input and output signal range allows to quickly solve questions on application of converters with different values of range and type of input signal. The parameters of the converters can be changed with the help of a specialised program "Configurator" or by buttons on the front panel. E1858EL are included in the State Register of SI of the Russian Federation No. 59809-15....
