Overview

The Control I/O Slave (IMCIS02) module interfaces between the process field signals and the Infi 90 Process Management System. It provides the communication link by bringing in four analog and three digital process signals for processing and monitoring, while outputting four digital and two analog signals for process control. The Control I/O Slave module works with master modules to perform the control functions, providing the I/O to these modules.
