Siemens Sitrans LR260 Guia De Inicio Rapido página 9

Connecting HART
Typical PLC/mA configuration with HART
Notes:
• Depending on the system
design, the power supply may
be separate from the PLC, or
integral to it.
• Loop resistance (total of cable
resistance plus 250 Ohm
[resistor]) must be less than
550 Ohm for the device to
function properly.
