description

The TxIsoPack-USB is a fully isolated 4 to 20mA two-wire loop powered temperature transmitter for in-head assembly.
Complete Sensor type selection and range configuration is achieved by connecting the device directly to a PC USB port thus not requiring any other interface, special converter or any additional driver.
The isolated and linearised current output represents the sensor input signal accoring to the temperature sensor selected.
Configuration of input type and working range is achieved using mini-USB cable (sold seperately) and TxConfig software..
