 19 Connection example for HART input (master mode) via current output (active)
1
Automation system with current input (e.g. PLC).
Prerequisite: automation system with HART version 6, HART commands 113 and 114 can be processed.
2 Cable shield, observe cable specifications
3 Resistor for HART communication (≥ 250 Ω): observe maximum load
4 Connection for HART operating devices
5 Analog display unit
6 Transmitter
7 Sensor for external measured variable
Potential equalization Requirements
No special measures for potential equalization are required.
Please consider the following to ensure correct measurement:
•
Same electrical potential for the medium and sensor
•
Company-internal grounding concepts
For devices intended for use in hazardous locations, please observe the guidelines in the
Ex documentation (XA).

Cable entries
• Cable gland: M20 × 1.5 with cable 
6 to 12 mm (0.24 to 0.47 in)
• Thread for cable entry:
– M20
– G ½"
– NPT ½"
Cable specification Permitted temperature range
• The installation guidelines that apply in the country of installation must be observed.
• The cables must be suitable for the minimum and maximum temperatures to be expected.
Power supply cable
Standard installation cable is sufficient.
Signal cable
Current output 4 to 20 mA HART
A shielded cable is recommended. Observe grounding concept of the plant.
Pulse/frequency/switch output
Standard installation cable is sufficient.
