Chassis Models
4.1 Single-Input Chassis
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 various configurations of Input channels, Output chan-
nels, or Virtual channels. This chapter describes the Model SC500 single-input
chassis.
4.1.1 Input Channel
The Model SC500 is a chassis whose small 1/8-DIN form factor allows for a single
Input channel identified as “Channel 01”. The type of Input channel installed in
the instrument is selected at the time of order. Input channels are available for a
wide variety of transducers including strain gage, AC/AC LVDT, RTD and high-
level voltage and current inputs. The Input Channel uses a 12-pin connector
located at the top, rear of the instrument.
If the DAC (Digital-to-Analog Converter) Output option is selected at the time of
order, then two pins of the Input Channel connector will be used for the DAC Out-
put.
4.1.2 Options Board
The Options Board is installed when optional features such as Limits (and their
Relay Outputs), DAC Output or RS-232/RS-485 communications are selected at
the time of order. The Options Board uses a 12-pin connector located at the bot-
tom, rear of the instrument.
4.1.3 Virtual Channels
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.
