ABSTRACT
With over 20 HART device categories, detailing their individual parameters here is not practical. So, listed below alphabetically, are general categories and types of devices available.
Actuator/Positioner: Linear and rotary actuators (positioners) are available, with positioning power supplied from electric, hydraulic, or pneumatic power sources. Some types include valve positioners, electropneumatic positioners, electric actuators, and hydraulic positioners. In these devices, Nominal 24 VDC electrical power supply is typical.
