Frequency CD2121 (CD 2121, CD-2121)
 
Frequency CD2121 designed to measure the frequency of industrial networks with a nominal frequency of 50 Hz and can be used to determine the power quality at the enterprises producing and consuming electricity.
Dimensions - 100h60h111mm.
 
Technical characteristics of the devices CD2121 frequency counters:
 
Frequency CD2121 allow you to perform the following functions:
- Measuring the frequency of industrial networks AC, 50 Hz;
- Digital display of measurement results
- Exchange of information on the RS-485-USB or RS-232-USB;
- Conversion of the measured frequency of the output signal strength uniform direct current from 0 mA to 5 mA, 0 mA to 20 mA of from 4 mA to 20 mA;
- Circuit switching loads on the comparison of the measured frequency to the predefined set points.Setpoint through software via RS485 or RS232;
Each of the devices frequency CD2121 combines the two measuring devices - the converter being measured in the current or the digital signal and the measuring device with digital display.
Constructively in the form of panel meters and replace outdated items F205, F246, TSD2120.1, TSD2120.2.
