ANALOGUE INPUT MODULE - (ADC03) - OVERVIEW

Allows the recording of up to 8 analogue signals to a VBOX data logging system.

  • Timer controlled transmission or polled response
  • Synchronous sampling of all channels
  • Internal scale and offset for conversion to real data
  • Wide voltage input range ±50 V
  • Bi-polar voltage input

How does it work?

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.

Connection is via the VBOX CAN bus, which means the modules can be placed very close to the sensors. This technique reduces noise compared with having long analogue signal cables running from the sensors to a main logging system.

CAN connectivity also means you can have multiple modules daisy-chained around the vehicle, all sharing the same Bus.

Inputs/Outputs

Each individual analogue channel can be separately configured for Units, Scale and Offset using the VBOX Setup Software. These values are stored inside the input module, which then transmits "real" values on the CAN bus to the VBOX.

This means that VBOX Test Suite and the Multi-function Display can show these values in real-time.
