DESCRIPTION
Symbols on equipment:
Means “Refer to User’s Manual
(this manual) for additional
information”.
DT335-0700 channels are modeled after ANSI/ISA Type IV transmitters. Input
channels interface with RTD sensors or resistance inputs and drive isolated DC
outputs of voltage or current. This dual channel device is unique in that it may
operate as a dual channel transmitter, a single channel transmitter, or channel 1
signal splitter. Units are setup, calibrated, and scaled using configuration software
and a USB connection to Windows-
based PC’s (Windows
7 and later versions only),
or using a USB-OTG cable to Android smartphones or tablets using the Agility
mobile app. Units provide adjustable/scalable input/output ranges, plus dual signal
output drive capability for voltage or current, input/output/power isolation for each
channel, and variable input filtering.
Key Features
•
Digitally configured and calibrated w/ Windows software via USB, or a wired
USB-OTG connection to Android smartphones or tablets.
•
Dual Channels in a thin 17.5mm wide enclosure for high-density mounting.
•
Operates as a dual transmitter, a single transmitter, or a CH1 signal splitter.
•
High measurement accuracy and linearity with 16-bit I/O conversion.
•
RTD input transmitter is linearized with respect to temperature (°C or °F).
•
Resistance input transmitter is linearized with respect to resistance (Ω).
•
Pt100, Pt200, Pt500, Pt1000, Copper, and Nickel type RTDs supported.
•
25Ω, 450Ω,
2250Ω, and 4500Ω resistive ranges also supported.
•
Connects to two-wire, three-wire, or four-wire RTD sensors.
•
Four-wire sensor wiring eliminates error associated with lead-wire resistance,
while three-wire sensor wiring compensates for lead-wire resistance.
•
Supports Celsius, Fahrenheit, and Kelvin temperature units.
•
Separate short-circuit protected voltage and current output terminals at each
output supports ±10V, ±5V, 0-10V, 0-5V, or 0-20mA, 4-20mA output.
•
Output channels can transmit Normal or Reverse Acting output signals.
•
Up or down-scale lead-break/burnout detection.
•
Both inputs and outputs are independently adjustable/scalable.
•
Variable input filter adjustment (none, low, medium, high).
•
Reverse-polarity protected 6-32VDC power is bus/redundant power ready.
•
Wide ambient temperature operation from -40°C to +70°C.
•
Thoroughly tested and hardened for harsh environments.
•
CE Approved.
•
FCC Conformity Class A
•
cULus Listed - Class I/Division 2 - Haz. Loc., ATEX, & IECEx.

DT300 dual transmitters are designed for high-density mounting on T-type DIN rails
and can be mounted side-by-side on 0.7-inch (17.5mm) centers and support 6-32V
DC power via terminals on the unit, or optionally via power wired to a DIN-rail bus
connector. This model interfaces with RTD or resistance elements, isolates the
input and allows it to mate with grounded or non-grounded signals, and provides an
output signal linearized to the RTD sensor temperature, or resistance. Unit drives
isolated outputs that source current or voltage from 0-20mA, 4-20mA, ±10V, ±5V, 0-
10V, and 0-5V.
