1.       General Informaion

HIC is electric-pneumatic valve positioner, which can be used in linear travel and angle travel actuator. It is a two-wire system device. Its power supply comes from 4—20mA input signal. The actuator can be single-action (spring recovery) or double-action (pneumatic open or pneumatic close).

Ø  The movement of actuator drives the resetting shaft of the positioner, passes on to the position sensor, then be transformed to electrical signal.

Ø  The inputted 4—20mA signal and actual position are passed on to CPU through A/D transforming. Microprocessor uses these data to calculate the control deviation by applying advanced algorithm, and drives the I/P module through PWM digital signal.

Ø  I/P module is the pneumatic output module of positioner. It includes guiding stage and simulative 3/3 slide valve assistant stage. The guiding stage transforms electrical signal into air pressure to drive the actuator through nozzle flapper and electromagnetic coil.

 

 

2. Technical Parameters
