Preface
The IMASO11 Analog Output (ASO) module outputs fourteen
analog signals from the INFI 90®OPEN Strategic Process Man-
agement System to process field devices. Control modules (i.e.,
MFP, multifunction processor or MFC, multifunction controller)
use these outputs to control a process.
This instruction explains the analog output module features,
specifications and operation. It details the procedures to set up
and install an analog output module. It explains troubleshooting,
maintenance and module replacement procedures.
The system engineer or technician using the ASO should read
and understand this instruction before installing and operat-
ing the output module. In addition, a complete understanding
of the INFI 90 OPEN system is beneficial to the user.
The IMASO11 Analog Output Module can be used as a direct
replacement of the IMASO01 Analog Output Module.

Safety Summary
®
GENERAL
WARNINGS Equipment Environment
All components, whether in transportation, operation or storage
must be in a noncorrosive environment.
Electrical Shock Hazard During Maintenance
Disconnect power or take precautions to ensure that contact with
energized parts is avoided when servicing.
Special Handling
This module uses electrostatic sensitive devices (ESD).
SPECIFIC
WARNINGS Disconnect power before installing dipshunts on the MMU back-
plane (I/O expander bus). Failure to do so could result in severe or
fatal shock. (p. 3-5, 5-3)
The outputs go to zero percent at start-up. On error detection, these
outputs will change to a fixed value. This value must be selected by
the user (and configured in the MFP) to ensure safe operation when
error conditions occur. (p. 3-2)
Never clean electrical parts of components with live power present.
Doing so exposes you to an electrical shock hazard. (p. 6-2)
Wear eye protection whenever working with cleaning solvents.
When removing solvents from printed circuit boards using com-
pressed air, injury to the eyes could result from splashing solvent as
it is removed from the printed circuit board. (p. 6-2)
There are exposed AC and DC connections inside the cabinet.
These exposed electrical connections present a shock hazard that
can cause injury or death. (p. 6-4)
If input or output circuits are a shock hazard after disconnecting sys-
tem power at the power entry panel, then the door of the cabinet
containing these externally powered circuits must be marked with a
warning stating that multiple power sources exist. (p. 6-4)

SECTION 1 - INTRODUCTION
OVERVIEW
The IMASO11 Analog Output (ASO) module outputs fourteen
separate analog signals that the INFI 90 OPEN system uses to
control a process. It is an interface between the process and
the INFI 90 OPEN Strategic Process Management System. Con-
trol modules perform the control functions; input/output mod-
ules provide the I/O.
This manual explains the purpose, operation and maintenance
of the IMASO11 output module. It addresses handling precau-
tions and installation procedures. Figure 1-1 illustrates the
INFI 90 OPEN communication levels and the position of the
ASO module within these levels.
