Hart modem electrical drawing  


HART modem - Cabling and wiring fundamental drawing - RS232 interface + resistor + 4-20 mA current loop + measure sensor + power supply.

The value of the resistor depends on the global resistivity in the current loop :

In some special cases, the resistor can have a lower value than the minimal value specified in the HART standard.
