Abstract
An asset management system includes a controller area network bus and a data acquisition module connected to the controller area network bus. The data acquisition module has a plurality of analog input channels. One or more sensor systems are connected to the input channels with the input channels receiving analog signals from the sensor systems. The data acquisition module passively conditions the received analog signals prior to digital conversion.
