Notes:

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 either be a HART or non-HART signaling device, a Primary Master or Secondary Master.

2.Network resistance equals the sum of the barrier resistances and the current sense resistor. Minimum value 250 Ohms; maximum value 1100 Ohms.

3.A maximum of 15 transmitters may be connected. All must be configured for digital mode.

4.Connect the MXC (a Secondary Master) to the loop only in the non-hazardous location. The MXC is a non-polar device.

5.Interconnect all cable shields and ground only at the power source.

6. For access to Model 344 terminals, remove enclosure end cap.
