INPUTS
Vega MT X CAN monitoring device has three multifunctional inputs that can operate in four modes:
Analog;
Digital;
Frequency;
Pulse.
In analog mode, the input voltage is measured. Such an input can be used for sensors whose
readings vary in a certain range.
Range of measured voltages of the analog input is 0…36 V
In digital mode, the input signal level (0 or 1) is measured. Such an input can be used for logic
sensors, the readings of which are determined by two states (on/off).
In frequency mode, the frequency of the pulse signal is measured. Such an input, for example, is
convenient to use for a car tachometer.
In pulse mode, the number of pulses at the input is counted. Such an input can be used for flow rate
sensors, for example, fuel consumption.
In the settings of multifunctional inputs in the “Configurator” program, in addition to selecting a
mode for each input, there is a parameter called “Active Level”. It can take the value “low” and “high” and
characterizes the magnitude and direction of the input tightening.
