1. The system power supply is shown separate from the host input device. In practice, it may be part of the host
input device. The host input device can be a HART or non-HART signaling device, a Primary Master or a
Secondary Master.
2. Network resistance equals the sum of the barrier resistances and the current sense resistor. Minimum value is
250 Ohms; maximum value is 1100 Ohms.
3. A maximum of 15 transmitters may be connected. All must be configured for digital mode.
4. Connect the HART Communicator as shown in Figure 2-2 for hazardous or non-hazardous locations. The HART
Communicator is a non-polar device.
5. Supply and return barriers are shown. Interconnect all cable shields and ground only at the barriers.
6. For access to transmitter field terminals, remove the enclosure cap.
