  • Page 21: Operation

    Section 2 OPERATION The TT400 WirelessHART accepts signals from mV generators such as thermocouples or resistive sensors such as RTDs. The criterium is that the signal is within the range of the input. For mV, the range is -50 to 500 mV and for resistance, 0 to 2000 Ohm. Functional Description-Hardware Refer to the block diagram (Figure 2.1).
