The Synchronous Versatile Input Module (SVIM) is a compact
expander that works in conjunction with an ACL or ADL3 Data Logger to
facilitate the synchronized logging of high-speed, high-resolution inputs.
The SVIM acquires data of the highest integrity for use in
advanced chassis and suspension analysis. It samples 18 inputs at the same
instant in time using 18 separate converters with 5th order anti-aliasing
filters.
Multiple SVIMs are synchronized so that every SVIM in the
vehicle samples its high resolution AV inputs at the same instant in time. This
is important when looking at the relationships of signals collected from
different sensors around the vehicle and is useful for test rigs and real time
simulations.
SVIMs are versatile in nature and can be located close to
sensors, reducing the weight and complexity of wiring. When used in multiples,
up to 200 sensor inputs are available. The SVIM supports many different types of
sensors, including unamplified thermocouples and strain gauges.
The SVIM is configured and controlled using the Data Logger
Manager software, that has special programming functions for the SVIM. This
will also automatically update the firmware version in the SVIM if necessary.
The Data Logger communicates to the SVIM via the CAN bus.
Compatible with:
- ACL (up to eight SVIMs)
- C185 (up to two SVIMs)
Inputs:
- 6 x Fast analogue voltage inputs
Update rate 5000 Hz (1000 Hz when used with ADL3),
resolution 12 bit
Used to measure the signals from sensors with variable
voltage outputs, such as potentiometers, 3-wire pressure sensors, thermocouple
amplifiers, accelerometers.
- 10 x High resolution analogue voltage inputs
Update rate 1000 Hz, resolution 15 bit
Used to measure the signals from sensors with variable
voltage outputs, such as potentiometers, 3-wire pressure sensors, thermocouple
amplifiers, accelerometers.
