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.

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.

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.

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.
