Overview

The IISAC01 Analog Control Station (SAC) is a single-loop process control and monitoring solution. It communicates with the Harmony controller via various modules, such as the CIO-100 control I/O block, IMCIS12 control I/O module, or IMQRS12 quick response module. This station incorporates advanced features over earlier digital control stations:

• Additional analog input display with square root option.
• High-resolution bar graph displays.
• Communication options supporting 5 or 40 kbaud serial links.

Specifications

Displays

• Three gas plasma bar graphs:
  • 200 segments for process variable and set point (0.5% resolution).
  • 100 segments for output (1.0% resolution).
• 8-character, 14-segment alphanumeric display.

Bypass

• Automatic entry or selectable from the faceplate.

Communication

• RS-485 serial link at 5 or 40 kbaud to the controlling module through the termination unit.
• Supports 40 kbaud with IMMFP11 and IMMFP12 modules (firmware revision E_0 or higher).
