DESCRIPTION
Symbols on equipment:
Means “Refer to User’s Manual
(this manual) for additional
information”.
The TT235-0600 is an ANSI/ISA Type 2 transmitter designed to interface with RTDs
(Resistance Temperature Detector), or resistive elements, isolate the input signal,
and modulate a 4-20mA current signal to drive a two-wire current loop. The
transmitter provides RTD sensor excitation, linearization, lead-wire compensation,
and lead break or sensor burnout detection. Configuration is performed using
software and a USB connection to Windows-
based PC’s (Windows XP and later
versions only).
Key Features
•
Fully configurable using Windows software via USB.
•
Thin 12.5mm wide enclosure for high-density DIN-rail mounting.
•
High measurement accuracy and linearity.
•
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 sensors.
•
Four-wire configuration eliminates error associated with lead-wire resistance.
•
Up or down-scale lead-break/burnout detection.
•
RTD inputs are linearized with respect to temperature.
•
Supports Celsius, Fahrenheit, and Kelvin temperature units.
•
Adjustable input range and selectable output ranges.
•
Input and output circuits are fully isolated from each other.
•
Convenient two-wire loop power with non-polarized output connections.
•
Normal or reverse acting output.
•
Namur compliant loop current.
•
Variable input filter adjustment.
•
Wide-range DC power input from 12
–
32VDC.
•
Wide ambient temperature operation.
•
Thoroughly tested and hardened for harsh environments.
•
CE Approved.
•
FCC Conformity Class B.
•
UL/cUL Class I, Division 2 Approved.
•
Model TT235-0600 is ATEX/IECEx Certified for Explosive Atmospheres.

Application

The TT235 transmitter is designed for high-density mounting on 35mm T-type DIN
rails. Modules may be mounted side-by-side on 0.5 inch (12.5mm) centers.
This model interfaces with RTD or resistive element inputs and isolates the input
signal allowing it to mate with grounded or non-grounded input signals. It provides
an output signal linearized to the RTD sensor temperature. Optionally, it can
support simple resistance input and drive an output signal linear with sensor
resistance.
