OVERVIEW
One Thermocouple Input Termination Module (NIAI02) is
required for each Thermocouple Slave Module (IMASM02).
Each NIAI02 can input eight thermocouple or millivolt signals
from field equipment to the thermocouple input slave module.
The signals pass through the slave module to the Analog Mas-
ter Module (IMAMM03).
This manual explains the purpose, setup, handling precau-
tions and steps to install the NIAI02 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 NIAI02 is a single printed circuit board that uses one slot
in a Termination Mounting Unit (NTMU01/02). The termina-
tion module (TM) has one card edge connector, P1. It connects
to the slave module through a cable. The terminal blocks for
field wiring are on the TM. The NIAI02 handles up to 8 thermo-
couple inputs for the IMASM02. Each input may be thermo-
couple or millivolt from -100 to +100 millivolts or 0 to 100
millivolts. Figure
shows an application example for the
NIAI02.
FEATURES
The design of the NIAI02, 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 thermocouple or millivolt
inputs.
•
Input signal routing to the IMASM02.
•
Source of the local cold junction reference.
