Length(ft) = [160,000 - 50,000pF] [50pF/ft] Length = 2200 ft. The HART communication cable length is limited by the cable characteristic capacitance. To increase cable length, select a wire with lower capacitance per foot. Contact your Emerson Process Management sales office for specific information relating to your control system.
Installation in Conjunction with a Rosemount 333 HART Tri‐Loop HART‐to‐Analog Signal Converter Use the DVC6200 digital valve controller in operation with a Rosemount 333 HART Tri‐Loop HART‐to‐Analog Signal Converter to acquire an independent 4‐20 mA analog output signal for the analog input, travel target, pressure, or travel. The HART Tri‐Loop accepts any three of these digital signals and converts them into three separate 4‐20 mA analog channels. Refer to figure 2‐29 for basic installation information. Refer to the 333 HART Tri‐Loop HART‐to‐Analog Signal Converter Product Manual for complete installation information. Figure 2‐29. HART Tri‐Loop Installation Flowchart START HERE
