Chapter 4 Chassis Models
4.1 Introduction
The SC 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 identi-
fied by a number (channel 01, channel 02, etc.).
A Virtual channel exists in software only; it does not occupy a
physical slot inside the instrument’s chassis. There is no rear-
panel connector for a Virtual channel. However, a Virtual channel
does require a channel number.
