The Bullet provides a switchable resistor connecting a 250 Ohm resistor between the 
HART and RETURN lead wires. To use the Bullet internal resistor the operator must 
properly configure the Device Description (DD). The operator must configure the DD 
parameter FIELD DEVICE POWER CONTROL to the – ON setting. Refer to section 2 
Configuration, Detailed Setting, Field Device Power Control section for the description 
and use of the Device Description and required operator setting.

Bullet with a 4-20mA Transmitter with Battery Powered Operation 

 

The Bullet is connected in series with a 4-20mA Transmitter, which can be analog only 

or HART capable.  An external battery or other power source (such as solar) is used to 
power the system.  The Bullet will duty-cycle power to the Transmitter to conserve 
power.   
 

 
Bullet installation to Field Device 

 

The Bullet typical installation to a field device is shown Figure 4. 
The Bullet is attached to the field device using the appropriate rated hardware as defined 
by the area classification of the installation.
