SPECIFICATIONS
Model Number
Model DT333-0700
Dual Output Signal Transmitter
Isolated TC/mV Input
Four-Wire w/ Isolated Power
CE Approved
Includes cULus Class I, Div 2,
ATEX/IECEx approvals
Custom calibration to your
specifications can be added as a
separate line item at time of
purchase.
The DT model prefix denotes a Dual Transmitter. The 3
rd
digit of 3 denotes a 4-wire,
separately powered transmitter type. The trailing 33 denotes a thermocouple/
millivolt input type from our DIN-Mounted DT300 Transmitter family.
The trailing “
-
0700
” model
suffix denotes a 4-wire transmitter with CE and cULus Class I, Division 2,
ATEX/IECEx Zone 2 Approvals.
Models can be mounted on standard 35mm
“T” Type DIN rail.
Optional factory
calibration to your own specification is ordered as a separate line item at time of
purchase, and on a per unit basis. Factory calibration will require the specification of
nominal input type/range, filter levels, lead-break detent, and if CJC must be set on
or off. You must also set an output current or voltage range, plus scaled input range
zero/full-scale values to corresponding output range zero/full-scale values. You can
also specify whether output is normal or reverse acting.
A Standard model without adding factory calibration is calibrated by default to
reference test conditions for T/C Type set to J, a 0°C to 200°C input range for both
channels, and inputs mapped to a normal acting 4.000mA to 20.000mA, with upscale
fault detection and channel CJC turned ON. Field recalibration of any model will
require use of the TTC-SIP configuration kit, ordered separately (see Accessories).
Input (Each)
This unit has separate isolated
input channels at TB1 and TB3 for
thermocouple or millivoltage
input signals.
This unit has three different
operating modes: dual
transmitter, single transmitter,
and CH1 signal splitter.
Input Reference Test Conditions:
TC Type J with at least a 10mV span (e.g. Type J
with 200
C span), or ±100mV range with a 10mV minimum calibrated span; Output
4-20mA; Ambient = 25
C; Power Supply = 24VDC.
Input Range & Accuracy:
Unit has two separate input channels at TB1 & TB3 for the
ranges indicated (unit provides TC linearization, Cold-Junction Compensation (CJC), &
lead break detection).

Note (Table 1):
Accuracy is generally ±0.1% of the full-scale span, typical, or per the
Table 1 specification, whichever is greater. Accuracy is given with CJC switched off.
CJC uncertainty should be combined with the numbers of Table 1 to determine
potential overall inaccuracy. Inaccuracy with CJC enabled may increase by as much
as
0.5
C during the post power-on warm-up period and will be
0.2
C typical after
reaching thermal equilibrium in about five minutes.
