13.MST2000 HART® Communications Information

13.1 Power and Loop Conditions

The MST2000 Multivariable differential pressure transmitter is a HART® conforming loop-powered 4-20 milliamp transmitter. Power connection is made at the two left terminal positions marked LOOP+ and LOOP-. Nominal power supply voltage is 24 volts DC which allows up to 600 ohms series resistance in the loop circuit. Higher loop resistance can be used with higher power supply voltages as required. See the loop resistance-voltage graph below in determining the minimum loop voltage required.

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 HCF_SPEC-54 (HART® FSK Physical Layer Specification, Revision 8.0) for additional information. The current sense resistor may be connected in either the high or low sideof the field loop wiring. HART® communication devices must be connected in accordance with HCF_SPEC-54 for proper operation. Typical connection methods are shown in the following diagrams.

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.
