OVERVIEW
The IMDSO01, IMDSO02 and IMDSO03 Digital Output (DSO)
Modules output eight isolated digital signals from the INFI 90
system to control a process. The signals provide digital switch-
ing (on or off) for process field devices. Control modules per-
form the control functions and I/O modules provide the input
and output signals. Figure
illustrates the position of the
DSO module within the INFI 90 architecture.
The DSO modules all function and operate the same. The only
difference is in the output switching capability and associated
fusing.
