IISAC01 Analog module

Description

Highlights
The IISAC01 Analog Control Station (SAC) provides process loop control and monitoring capabilities for a single loop. The analog control station receives and sends information to and from the
Harmony controller through the CIO-100 control I/O block, the IMCIS12 control I/O module, or
the IMQRS12 quick response module. It includes features not found on earlier digital control
stations:
■ Additional analog input display with square root option.
■ High resolution bar graph displays.
■ Five or 40-kilobaud serial link.
