EX200 HART  -  A SMART CONTROL SYSTEM FOR ELECTRO-HYDRAULIC ACTUATORS

 

The EX200-HART gives all the functions of the popular EX200 with the addition of HART protocol data on either the actual position or the command signals. The HART commands incorporate all Universal and a selection of Common Practice commands, all conforming to HCF V7. Additional Device Specific commands allow the remote configuration of certain aspects of the instrument. A PC based host application, SW002, is available for setting up the EX200-HART.

The EX200 is an essential component in the control of electro-hydraulic actuators.This compact instrument switches the solenoids of the actuator such that it moves to the position dictated by an incoming analogue command signal. The actual position of the actuator, measured by a position transducer, is conditioned by the EX200 and re-transmitted back to the central control system as a scaled analogue signal.

 

The positioner is calibrated by a simple two-step procedure. Other features include actuator speed control by pulsing the control solenoids, signal break and fault detection with default positioning and hydraulic pump control.
