Temperature Transmitter - TxIsoPack-USB

Temperature Transmitter - TxIsoPack-USB
Brand: Novus - Model: 8807000000

* TxIsoPack-USB is a fully isolated 4 to 20 mA 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 linearized current output represents the sensor input signal according to the temperature sensor selected.
