Description
The TxIsoPack – USB is an isolated two-wire 4-20 mA temperature transmitter for head mounting. Powered by the current loop, it is configured by connecting the transmitter directly to the PC’s USB interface, without requiring any additional driver.
The output current represents the signal applied to the transmitter input, linearized according to the configured input type.
