SECTION 1
Model Numbers and Options
The following section provides details of the Moore Industries model number and the available
options for the THZ
3
and TDZ
3
.
Moore Industries model numbers for the THZ
3
/TDZ
3
are structured as follows:
THZ
3
/ PRG / 4-20MA / 12-30DC / [HPP]
Unit / Input / Output / Power / - Options [Housing]
Refer to
Section 9 Ordering Information
for a quick reference table of ordering information.
Further details are provided for each model below.
INPUT
PRG
The THZ
3
/TDZ
3
supports one or two RTD, T/C, mV, Potentiometer and Ohms as configurable
inputs.
The input field of the model number string can also specify the specific sensor in a temperature
transmitter assembly (see RTI series data sheets for more information). If a second sensor is
required in the assembly then this needs to be ordered separately.
Note:
While the THZ
3
/TDZ
3
will accept a dual input sensor configuration the following
limitations apply only when using two input sensors:
TDZ
3
[HP]
– 2-wire and/or 3-wire sensors. 4-wire sensors (RTDs) cannot be used.
THZ
3
[DIN]
– (see figure 3.2) 2-wire and/or 3-wire sensors. 4-wire sensors (RTDs) cannot
be used.
THZ
3
[HPP]
– (see figure 3.4) Sensor 1 can be configured as 2-wire or 3-wire sensor.
Sensor 2 is then restricted to a 2-wire sensor.
OUTPUT
4-20MA
The isolated analog output provides a 4-20mA signal (scalable to narrower ranges) with a HART
signal superimposed.
POWER
The THZ3 and TDZ3 are 2-wire, loop powered instruments. They are powered either by an
external power supply, or by a DCS (or PLC) input channel that provides power to the loop.
12-42DC
12-42Vdc is the standard power range.
12-30DC
To specify units for installation in intrinsically safe areas, specify the 12-30Vdc power option. This
option is not applicable to DIN housing.
