With remote meter and/or any peripheral device, the voltage drop for these options must be
added to the basic 10.8-volt (for HART) & 15-volt (for DE) supply requirements to determine
the required Transmitter voltage (VXMTR) and maximum loop resistance (RLOOP MAX).
Additional consideration is required when selecting intrinsic safety barriers to ensure that they
will supply at least minimum Transmitter voltage (VXMTR MIN), including the required 250
ohms of resistance (typically within the barriers) needed for digital communications.

5.3 Wiring Variations

The above procedures are used to connect power to a Transmitter. For loop wiring and external
wiring, detailed drawings are provided for Transmitter installation in non-intrinsically safe areas
and for intrinsically safe loops in hazardous area locations.
If you are using the Transmitter with Honeywell's TPS system, see PM/APM SmartLine
Transmitter Integration Manual, PM12-410, which is part of the TDC 3000

5.3.1 Input Sensor Wiring

Connect the input sensors as shown in Figure 15

5.3.2 RTD Connections

Resistance temperature detector (RTD) measurements use the 3 or 4 wire approach. The
transmitter determines by itself if a 3 or 4 wire RTD is connected when powered up.
