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
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
for the
steps to set the module address. Refer to
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
for the correct setting of these jumpers.
