Programmable Isolated
Thermocouple Transmitter
Introduction
Moore Industries’ Programmable Isolated Thermo-
couple Transmitter (TIY) is a 2-wire, microprocessor-
based instrument that converts thermocouple or
millivolt input into 4-20 mA output. The output is
field-configurable to be linear with temperature or
millivolt input.
The highly accurate TIY features easy-to-use mem-
brane push buttons (referred to as “push buttons” in
the manual) and solderless jumpers for easy field
calibration and configuration.
This manual contains the information necessary to
calibrate, install, operate, maintain, and troubleshoot
the TIY. It includes a brief unit description, a table
of performance and operational specifications, and
an explanation of Moore Industries’ model/serial
number-based product data tracking system.
The following guidelines are used throughout the
manual:
WARNING – Hazardous procedure or condition that
could injure the operator.
Caution – Hazardous procedure or condition that
could damage or destroy the unit.
Note – Information that is helpful for a procedure,
condition, or operation of the unit.
Description
The TIY is a loop-powered, thermocouple transmit-
ter that accepts input from standard ISA thermo-
couples (types J, K, E, T, R, S, or N) or a millivolt
source, and produces proportional 4-20 mA output.
Front panel push buttons set zero and span (full-
scale) values. These values remain until they are
changed by the user.
An LCD provides readouts of the applied input (ei-
ther in temperature or millivolts), displays problem
codes, and is used for quick ranging.
Several functions of the TIY are configured with
solderless jumpers. Each of these jumpers is ac-
cessible without disassembling the unit. The jump-
er-selectable features include:
• Reference junction compensation/no reference
junction compensation
• Degrees Fahrenheit/Celsius
• Upscale/downscale burnout
• Linearization/no linearization of the output
• Quick/standard ranging
The TIY is available in two housing styles: Hockey-
puck (HP) and DIN-style. The TIY’s application will
determine which housing style is suitable.
The HP-style housing is equipped with spring clips
for mounting in an explosion-proof enclosure. The
TIY packaged in an HP-style housing and equipped
with flange plates (FL housing option) is designed
to mount on a flat surface or on relay tracks (refer
to the Installation Section). The all-aluminum DIN-
style housing snaps directly onto standard G-type
or Top Hat rail.
The performance and operational specifications for
the TIY are next. Refer to the Installation Section
for the outline dimensions of both housing styles
and to the Calibration section for span accuracy
information.
