SECTION 1 - INTRODUCTION
OVERVIEW
The RTD Analog Input Termination Module (NIAI03) is used by
the RTD Analog Slave Module (IMASM03/04). Each NIAI03 can
input eight three-wire RTD signals from field equipment. The
signals pass through the slave module to the Analog Master
Module (IMAMM03). This manual explains the purpose, setup,
handling precautions and steps to install the NIAI03 termina-
tion module.
INTENDED USER
System engineers and technicians should read this manual
before installing and using the termination module (TM). Put
the module into operation only after reading and understand-
ing this instruction. Refer to the
Table of Contents
to find the
information. Refer to the
entry in
this section to get started.
MODULE DESCRIPTION
The NIAI03 is a single printed circuit board that uses one slot
in a Termination Module Mounting Unit (NTMU01/02). The
termination module (TM) has one card edge connector that
connects to the slave module through a cable. The terminal
blocks for field wiring are on the TM. The NIAI03 handles up to
eight three-wire RTD inputs for the IMASM03/04. Figure
shows an application example for the NIAI03.
FEATURES
The design of the NIAI03, 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 TM in an INFI 90 system.
•
A standard factory-wired cable connects the TM to the
slave module.
•
Connect I/O wires on terminals at the front edge of the TM.
•
Each TM fits in a standard termination mounting unit.
•
Field wire termination for eight three-wire RTD inputs.
•
Input channel transient and surge protection.
•
RTD input signal routing to the IMASM03/04.
