SECTION 1 - INTRODUCTION
OVERVIEW
The NIAC03 Analog Input Calibration Module is required to
calibrate the IMASM03 Analog Slave Module (100 ohm resis-
tance temperature detector (RTD)). Calibration resistances are
read from the NIAC03 module through the IMASM03 slave
module. Calibration values are read across the slave expander
bus and processed by the IMAMM03 master module.
This manual explains the purpose, setup, handling precau-
tions and steps to install the NIAC03 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 NIAC03 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 NIAC03 module select one
input at a time to be calibrated for zero or span.
HARDWARE APPLICATION
The NIAC03 module has on-board precision resistors on the
termination module that are used to calibrate the zero and
span of the slave inputs. The IMASM03 module must be physi-
cally moved to the dedicated calibration slot. The associated
IMAMM03 module issues the calibration commands to the
IMASM03 module. Figure
shows an application example
for the NIAC03 module.
FEATURES
The design of the NIAC03 module, as with all INFI 90 devices,
allows for flexibility in creating a process management system.
