SECTION 1 - INTRODUCTION
OVERVIEW
The NIAC04 Analog Input Calibration Module is required to
calibrate the IMASM04 Analog Slave Module (10 ohm RTD).
Calibration resistances are read from the NIAC04 module
through the IMASM04 module. Calibration values are read
across the slave expander bus and processed by the IMAMM03
master module.
This manual explains the purpose, set up, handling precautions
and steps to install the NIAC04 module. Calibrate the slave
according to the IMAMM03 product instruction. Refer to the
Table of Contents
to find the information. Refer to the
entry in this section to get started.
INTENDED USER
System engineers and technicians should read this manual
before installing and using the termination module. Put the
module into operation only after reading and understanding
this instruction.
MODULE DESCRIPTION
The NIAC04 module is a single printed circuit board that uses
one slot in a NTMU01 or NTMU02 Termination Mounting Unit.
The module has one card edge connector (P1) that connects to
a slave module mounted in a dedicated calibration slot,
through a cable. Jumpers on the NIAC04 module select one
input at one time to be calibrated for zero or span.
HARDWARE APPLICATION
The NIAC04 module has on-board precision resistors that are
used to calibrate the zero and span of the slave inputs. The
IMASM04 module must be physically moved to the dedicated
calibration slot. The associated IMAMM03 module issues the
calibration commands to the IMASM04. Figure
shows an
application example for the NIAC04 module.
FEATURES
The design of the NIAC04 module, as with all INFI 90 devices,
allows for flexibility in creating a process management system.
Refer to the
entry of this section for the list
of devices that can be used with the calibration module in an
INFI 90 system.

A standard factory-wired cable connects the calibration
module to the slave module.
