VBOX Analogue Input Module (ADC03)
ADC03
●Record up to 8 analogue signals to a VBOX
●Wide voltage input range ±50 V
●Synchronous sampling of all channels
●Bi-polar voltage input
●Internal scale and offset for conversion to real data
●Timer controlled transmission or polled response
Overview
The VBOX Analogue Input Module (ADC03) is an 8-channel, 16-bit analogue voltage interface for use with the VBOX range of GPS data loggers.
Each channel is electrically isolated and provides bipolar voltage measurement up to ±50 V with a DC accuracy of ±2 mV (calibrated at 23 °C). Isolated, regulated 5 V and 12 V supplies are available on the main 25-way Sub-D connector, in addition to a supply voltage connection.
How It Works
Connection is via the VBOX CAN bus, so modules can be placed very close to the sensors. This reduces noise compared with running long analogue signal cables from the sensors to a main logging system.
CAN connectivity also means multiple modules can be daisy-chained around the vehicle, all sharing the same bus.
Each analogue channel can be configured separately for units, scale and offset using VBOX Setup software. These values are stored in the module, which then transmits real values on the CAN bus to the VBOX, so VBOX Test Suite and the Multi-Function Display can show them in real time.
