Wire entrance is per two PG20 conduit openings as shown in Figure 8. The top entrance is for<br />
power; the bottom, for inputs and outputs. Optional 1/2 NPT and 3/4 NPT cable glands are<br />
available for use with these conduit openings.<br />

Input/Output Wiring<br />
The maximum length of signal wires for HART ® communication is 3050 m (10,000 ft). It is<br />
1525 m (5000 ft) in multidrop mode.<br />
Input/Output connections depend on the output signals that were specified for your particular<br />
transmitter. The output signals available for your transmitter can be determined from the model<br />
number on your transmitter data plate as follows:<br />
CFT50-1EA#BK<br />
