SECTION 1 - INTRODUCTION
OVERVIEW
The Controller Module (IMCOM03-Enhanced/04-Advanced) is
an INFI 90
®
plug-in module. Implementation of analog and dig-
ital control strategies is the primary purpose of this module. A
variety of control functions is available for the user to custom
design the control scheme, making the controller module a ver-
satile and powerful element of the INFI 90 system.
The Controller Module (IMCOM03/04) is a stand-alone control-
ler that can be dedicated to one or two loops. It brings four
analog and three digital process field signals into the INFI 90/
Network 90
®
system for processing and monitoring. It outputs
four digital and two analog signals for process control. The
controller module can control the process and communicate to
the communication network. The COM can communicate with
the INFI-NET
®
or plant loop communication networks. The
COM performs the control functions and provides the I/O. The
INFI 90 Controller Module (IMCOM03/04) is a direct replace-
ment for the Network 90 Controller Module (NCOM03/04).
This manual explains the purpose, operation and maintenance
of the controller module. It addresses handling precautions
and installation procedures. Figure 1-1 shows the INFI 90 sys-
tem and the position of the COM module.
INTENDED USER
System engineers and technicians should read this manual
before installing and operating the COM module. A module
SHOULD NOT be put into operation until this instruction is
read and understood. Refer to the Table of Contents to find
specific information after the module is operating.
MODULE DESCRIPTION
The COM consists of a single printed circuit board (PCB) that
occupies one slot in a module mounting unit (MMU). A
dipswitch on the PCB configures each of the analog outputs;
jumpers configure each of the digital inputs. Each analog input
is configured on its Termination Unit (TU) or Termination
Module (TM).
Two captive latches on the faceplate secure the module to the
MMU. A front panel LED indicates the module status.
