4.0 CHASSIS MODELS
4.1 Introduction
The DFI Series of Signal Conditioners/Indicators are available in several different chassis models. In general, each
chassis model operates in an identical fashion and can be ordered with any type of Input channels, Output
channels, or Virtual channels.
Input channels and Output channels are printed circuit boards that occupy a physical slot inside the instrument’s
chassis. 12-pin connectors are located on the rear panel to connect to each Input or Output Channel. Each
channel in the instrument is identified by a number (channel 01, channel 02, etc.).
A Virtual channel exists in software only; it does not occupy a physical slot inside of the instrument’s chassis.
There is no rear-panel connector for a Virtual channel. However, a Virtual channel does require a channel number.
