Current and Voltage Data Collection Device "Passer-T" for Industrial Equipment Monitoring

Current and voltage data acquisition device "Passer-T" is a part of LimanISU-Monitor PAC, provides automated diagnostics of equipment technical condition at industrial enterprises. Operating principle of "Passer-T": input signals of current and voltage through matching circuits come to the input of analogue-to-digital converter, which produces analogue-to-digital conversion of instantaneous values of measured signals of industrial frequency 50Hz and transmits data to the microcontroller. It provides calculation of electrical network parameters, averaging of measured and calculated parameters, processing of discrete inputs states, data exchange with external systems via Ethernet interfaces.Serial number, service information, calibration coefficients set at factory setting, as well as user settings are stored in non-volatile memory.Current, voltage, discrete inputs and outputs, interfaces and power supply circuits of the Passer-T are galvanically isolated from each other and the housing.
