Overview

The IMDSO04 is a Digital Slave Output module used in the Infi 90 system, providing 16 digital output signals to control field devices. It acts as an interface between the process and the Infi 90 Process Management System. While master modules handle control functions, slave modules like the IMDSO04 handle I/O operations.
