13.MST2000 HART® Communications Information
13.1 Power and Loop Conditions
The MST2000 Multivariable differential pressure transmitter is a HART® conforming
Note: For HART® communication applications, minimum loop resistance is 250 ohms.
13.2 HART® Connections
Maximum resistance versus DC loop voltage
All electrical connections are per standard HART® connections. Refer to HART® Communication Foundation Document
13.3 CablingRequirements
The field wiring of a HART® based system should use shielded twisted pair cable. When using cable with multiple twisted pairs, it is important not to use the other pairs for signals that might interfere with the HART® communication signals.
Typical multi-drop
connection with digital communications.
