Overview

The IMCIS12 Control I/O and IMQRS12 Quick Response I/O modules are designed to interface between the process and the INFI 90 OPEN Strategic Process Management System. They bring four analog and three digital process field signals into the system for processing and monitoring. Additionally, they output four digital and two analog signals for process control.

• Control I/O (CIS): Interfaces with the system to process signals.
• Quick Response I/O (QRS): Provides faster response time for process control.
