Preface
The Universal Analog Input Slave Module (IMASI03) interfaces
field inputs to the multi-function processor module. The
IMASI03 supplies 16 separate process field signals into the
INFI 90®Process Management System. These analog inputs are
used by the Multi-Function Processor Module (MFP) to monitor
and control a process.
Universal analog input slave modules provide an isolated ther-
mocouple, millivolt, RTD, and high level analog signal interface
for the Multi-Function Processor Module with variable ana-
log-to-digital conversion resolution up to a maximum of 24
bits.
This instruction explains the slave module features, specifica-
tions and operation. It details the procedures to set up and
install an IMASI03 module, and explains status indicators that
help in system test and diagnosis.
System engineers or technicians using the IMASI03 should
read and understand this instruction before installing and
operating the slave module. In addition, a complete under-
standing of the INFI 90 system is beneficial to the user.

OVERVIEW

SECTION 1 - INTRODUCTION
OVERVIEW
The Universal Analog Input Slave Module (IMASI03) performs
analog input signal processing for up to 16 input channels and
sends this information to a Multi-Function Processor
(IMMFP01/02/03) in the INFI 90® System.
This manual explains the purpose, operation, maintenance,
handling precautions and installation procedures of the slave
module.
INTENDED USER
System engineers and technicians should read this manual
before installing the IMASI03 module. Put the module into
operation only after reading and understanding the informa-
tion in this manual. Refer to the Table of Contents to find spe-
cific information. Refer to the HOW TO USE THIS MANUAL
entry in this section to get started.
MODULE DESCRIPTION
The IMASI03 is a single printed circuit board that occupies one
slot in an INFI 90 Module Mounting Unit (MMU). Two captive
latches on the module faceplate secure it to the MMU. The
slave module has three card edge connectors for external sig-
nals and power: P1, P2 and P3. P1 connects to the supply volt-
ages. P2 connects the IMASI03 to the slave expander bus, over
which it communicates with the MFP.
Connector P3 carries the inputs from the input cable plugged
into the termination unit (TU) or termination modules (TM).
The terminal blocks for field wiring are on the TU/TM.
The single dipswitch on the IMASI03 module sets the address
for the slave or selects on-board tests. Refer to Section 3 for the
steps to set the module address. Refer to Section 6 for the
on-board tests. Be sure to check the switch setting before put-
ting the module into the MMU.
Jumpers configure the type of analog input signals. Refer to
Section 3 for the correct setting of these jumpers.
Figure 1-1 shows the INFI 90 communication levels.

FEATURES
The design of the IMASI03 module, as with all INFI 90 mod-
ules, allows for flexibility in creating a process management
system. Refer to the NOMENCLATURE entry of this section to
see the list of devices that can be used with the slave module in
an INFI 90 system.
•The IMASI03 conditions (filters, amplifies and isolates) up
to 16 analog input signals.
•The IMASI03 converts analog signals to digital values, adds
compensation and corrections as needed, and provides dig-
ital values to the MFP through the slave expander bus.

•Each channel is individually programmable for these input
types:
E, J, K, L, N (14 AWG), N (28 AWG), R, S, T, U thermocouples.
Chinese type E and Chinese type S thermocouples.
Millivolt (-100 to +100 mV).
3-wire RTDs (10, 100 U.S., 100 European, 120 and Chinese
53 Ohm).
High level (-10 to +10 V).
Current (4-20 mA).
•Resolution of the analog-to-digital conversion process is
programmable over a range from 16 to 24 bits.
•Input type and channel resolution may be selected inde-
pendently for each channel, permitting any mix of inputs
on a single IMASI03 module.
•Channel isolation and open input detection are provided
for each channel.
•Input circuit offset, gain and nonlinearity errors are
recorded during a one time factory calibration procedure.
These measurements provide error compensation during
normal operation. The slave does automatic recalibration
during normal operation to compensate for component
aging and temperature drift. No user calibration is ever
required.
•Engineering units conversion to degrees C or F is automat-
ically calculated on all input signals that are thermocouple
or RTD types. These conversions correct for nonlinearities
in the conversion to temperature units using industry
standard linearization tables.
•The slave scales the block output value to engineering
units for low and high level voltage inputs. Input type and
zero and span values are specified in function code 216.
•Thermocouple inputs have cold junction compensation.
Each termination device has a built-in cold junction refer-
ence. The cold junction reference applied to thermocouple
inputs may be this built-in reference or it may be a remote
reference read from another input from this or another
slave.
•The slave compensates for lead wire resistance in the con-
nection between the thermocouple, RTD or low level voltage
input signals.
•The IMASI03 can be removed or installed without turning
off power to the system.
