Connecting the 4–20 mA Analog Signal

Cabling considerations

If possible, use individually shielded twisted pair cable, either in single pair or multi-pair 
varieties. Unshielded cables may be used for short distances, provided ambient noise and 
cross-talk will not adversely impact communication. The minimum conductor size is 0.51 
mm diameter (#24 AWG) for cable runs less than 1,500 meters (@ 5,000 ft.) and 0.81 mm 
diameter (#20 AWG) for longer distances. Resistance in the loop must be 1000 ohms or 
less.

Powering the 4-20mA Output

For transmitters with non-I.S. Output, the 4–20 mA output signal may be powered internally 
or externally. The default position of this switch is in the internal position and is located on 
the front of the electronics board.

8732E terminal connections

Connect negative (-)DC to Terminal 1 and positive (+)DC to Terminal 2. See Figure 19.

Internal Power Source

The 4–20 mA analog signal loop is powered from the transmitter itself. 

External Power Source 

The 4–20 mA analog signal loop is powered from an external power source. HART 
multidrop installations require a 10–30 V DC external analog power source.

NOTE:

If a HART Field Communicator or control system will be used, it must be connected across a 
minimum of 250 ohms resistance in the loop.

To connect any of the other output options (pulse output and/or digital input/output), consult 
the comprehensive product manual.
