3INTRODUCTION

The TxRail-USB is an USB configurable DIN rail mount temperature transmitter. It allows selection and configuration of input type, measurement

range, output type and calibration. Its output can be set to either loop powered 4-20 mA or 0-10 Vdc. Highly accurate and user-friendly, the

TxRail-USB performs well from simple to sophisticated measurement applications.

The output current or voltage is linearized according to the selected input sensor and adjusted to the configured range.

magnetic interference, high voltage and other interferences can

permanently damage the unit, and could cause error in the

measured value Abmessungen

Öffnen des Messumformers

To open the transmitter, you must press the orange lockers

located on both sides of the enclosure and pull the frontal cover very

carefully, just like shown in Fig. 2.

BBILDUNG

•Recommended torque fort he connection screws: 0.8 Nm

Recommendations for Installation

•Conductors of small electrical signals must be distant from Power supply and high-tension/current conductors, preferably passing

through grounded conduits.

•A specific electrical power supply network should be provided for instruments use only

•In controlling and monitoring applications, possible consequences of any system failure must be considered in advance.

•RC filters (47R an 100nF, serial) in inductor charges (contactors, solenoids, etc.) are recommended

Electrical Connections

The figures below show the electrical connections required. The terminals 1, 2, 3 and 4 are dedicated to the sensor connection. LOAD

represents the 4-20 mA current or 0-10 V voltage measuring device (indicator, controller, recorder, etc.).

6.2.1 Pt100 2-wires / NTC

Note: When the Pt100/Pt1000 2-wire the terminals 1 and 3 must be interconnected,

according to the figure below. To use the Pt100/Pt1000 2-wire, you must configure the

Pt100/Pt1000 3-wire option in TxConfig II. The Pt100/Pt1000 wire length should be less than

30 cm to

maintain the measurement error within specifications (electrical

resistance).

6.2.2 Pt100 3-wires

6.2.3 Pt100 4-wires

Pt100 3 and 4-wire: For appropriate cable resistance compensation they should be equal for all legs. Maximum wire resistance is 25 Ω per

wire leg. Usage of a 3 or 4 wire with conductors of equal length and gauge is recommended.

7CONFIGURATION

Changes to the configuration are possible through the TxConfig II software, provided free of charge. The transmitter configuration interface

(USB cable) can be purchased from the manufacturer or its authorized sales representatives.

The TxConfig II software is continuously updated, and new versions can be downloaded at no charge from the manufacturer’s website. To

install, execute the TxConfigIISetup.exe file and follow the instructions.

During the setup, the transmitter is powered by the USB, not requiring an external power supply. The transmitter setup can also be made by

connecting it to the loop, using the loop power supply. There is no electrical insulation between the transmitter and the communication port

(interface), therefore it is not recommended to configure it with the sensor inlet connected to the process. See Fig. 2

After these connections, the user must run the TxConfig II software and, if necessary, consult the Help topic to help using the software.

The USB communication port (interface) of the TxBlock-USB is not electrically insulated from the transmitter’s

input.

Software Configuration

The fields in the screen mean:

1. General Information: This field shows information that identifying the transmitter. This information should be sent to the manufacturer

in an eventual request for technical assistance.

2. Sensor: Select the type of sensor to be used. See Table 1.

3. Measuring Range: Sets de measurement range of the transmitter.

a. Lower Range Limit: Desired temperature for minimum retransmission value.

b. Upper Range Limit: Desired temperature for maximum retransmission value.

c. Sensor Range The values chosen cannot exceed the range of sensor shown in this field. See Table 1 of this manual.

d. Minimum Range Do not set a lower band (span) that the Minimum Range indicated below in this same field. See Table 1 of

this manual.

4. Sensor Failure: It establishes the output behavior, when the transmitter indicates a failure:

a. Minimum: output current goes to < 3.8 mA or output voltage is 0 V (down-scale), typically used for refrigeration.

b. Maximum: output current goes to > 20.5 mA or output voltage is 10 V (up-scale), typically used for heating.

5. Zero Correction: It corrects small deviations presented in the transmitter output, for example, when the sensor is replaced.

6. Send Configuration: It applies the new setup. Once sent, the setup will be immediately adopted by the transmitter.

7. Read Configuration: Reads the current setup in the transmitter connected. The screen now presents the current setup that may be

changed by the user.

any measurement errors. See item Zero Correction in the chapter CONFIGURATION of this manual.

The user must choose the most suitable sensor and range to the process. The chosen range must not exceed the maximum range of

measurement defined for the sensor and should not be smaller than the minimum range for the same sensor.

It is important to note that the transmitter accuracy is based on the maximum range of the sensor used, even when a narrower

range is programmed. Example:

The Pt100 sensor in the range 0 to 100 °C and accuracy of 0.12 %, the maximum error will be 1.02 °C (0.12 % de 850 °C).

The Pt100 sensor in the range 500 to 600 °C and accuracy of 0.19 %, the maximum error will be 1.61 °C (0.19 % of the 850 °C).

Note: When measurements are made at the transmitter, see if the Pt100 excitation current required by the calibrator is compatible with the

Pt100 excitation current used in the transmitter: 0.8 mA
