TxIsoPack

TEMPERATURE TRANSMITTER – OPERATING MANUAL V1.1x C

INTRODUCTION

The TxIsoPack is an 4-20 mA 2-wire isolated temperature transmitter, for

head assembly. Powered by the current loop, its configuration is

accomplished by connecting the transmitter directly to the PC USB interface,

not requiring installation of additional drivers.

The output current is linearized and adjusted in fuction of the input sensor

type and range configured.

CONFIGURATION

When the transmitter is already configured with the sensor and desired

ranges, no intervention is necessary and its installation may be executed

immediately. When it is necessary to change the configuration, it should be

made through the TxConfig software.

USB cable and TxConfig software make up the Transmitter Setup Kit that

can be purchased from the manufacturer or any authorized representative.

The setup software may be updated at no charge at the manufacturer’s

website. To install, execute the file Tx_setup.exe and follow the instructions.

Fig. 1 – USB cable connections

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.

Fig. 2 – USB cable connections – Loop powered

After these connections, the user must run the TxConfig software and, if

necessary, consult the Help topic to help using the software.

The USB communication port (interface) of the

TxIsoPack is not electrically insulated from the

transmitter’s input.
