VT2808
Current Measurement Module
The module VT2808 provides 8 inputs for analog signals for voltage and current measurement. They may be connected directly to the outputs or load path of an ECU.
Current Measurement Module: VT2808
Characteristics:
VT2808
Functions for Each Channel
- Current measurement with 3 measurement ranges (automatic range switching)
- Simultaneous voltage measurement
- Measurement related to external reference or ground (switchable)
- Alternatively, current measurement with an external measuring resistor
- Calculation of instantaneous, maximum, and minimum values from the raw measurement values of the A/D converter; access to these values within CANoe
