HART Communications
The HART Communicator interfaces with any HART device from any wiring termination point in a 4-20 mA
loop, provided a minimum resistance of 250 ohms is present between the communicator and power supply.
The HART Communicator uses the Bell 202 frequency shift keying (FSK) technique. This technique superim-
poses high-frequency digital communication signals on the standard 4-20 mA transmitter circuit loop.
Because the net energy added to the loop is zero, communication does not disturb the 4-20 mA signal.
