Digital frequency meters are suitable for power grids and automation control systems, mainly measuring frequencies in the grid. According to their additional functions, they can be divided into X/K series of digital display instruments.
The X series intelligent digital frequency meter is a digital power meter that measures the frequency of the power grid and directly displays it through a digital tube (LED) or liquid crystal (LCD) on the meter head.
The K series intelligent digital frequency meter adds a variable ratio keyboard function on the basis of the X series. Optional functional modules include:
/C - Communication function (instrument data is directly displayed on the computer and can be printed out, RS485 communication interface, standard Modbus RTU protocol);
/M - Analog output (when the instrument is working, it can output one or three sets of isolated analog signals, which are linear with the displayed value, and the output power is DC4-20mA, DGO-5V, DCO-10V);
J - Relay alarm output, two relay alarm outputs, the upper and lower line alarm values can be set freely.
/K-switch input/output (I/O) module;
