POWER
SUPPLY
CONNECTING HART
Typical PLC/mA configuration with HART
Depending on the system design, the power supply may be separate from the PLC, or integral to it.
HART resistance (total loop resistance, that is, cable resistance plus 250 Ohm (resistor) must be less than 550 Ohm for the
device to function properly.
