Multichannel measurement data acquisition device for microprocessor-controlled data recording, comprises input channels operatively connected to data storage unit, and power supply unit for providing input channels with supply voltages

摘要

The multichannel measurement data acquisition device (G) comprises input channels (EK1,EK2), a data storage unit (SM) and a power supply unit (EV). The input channels are operatively connected to the data storage unit to record the measurement signals received in the data storage unit through the input channels as measurement data. The power supply unit is arranged to provide the input channels with supply voltages (T1,T3), where the value of the former supply voltage is different from the value of the latter supply voltage. A process interface element (P1,P2) is coupled to the input channels.
