Honeywell SmartLine SLG 700 - Figure 2-2: Example of HART Connection RL

Revision 8 SLG 700 SmartLine Level Transmitter User’s Manual Page 7
Figure 2-2 is an example of a HART connection to the transmitter. The communication
resistor RL may be inserted anywhere in the 4-20 mA loop but it is recommended to be
installed close to the positive supply. Refer to section 0 for acceptable power supply and RL
ranges
The MC Toolkit is a dedicated Honeywell communication tool that uses Device Description
(DD) files to communicate with multiple transmitter models. Also, other equivalent tools or a
HART-to-USB converter may be used. Device Description files are available from:
