second generation intelligent executive IQ35,Analog 4-20mA.Actuator
for Valve Position Feedback Si
(1) Convenient remote parameter setting function. Before putting
into use, as long as the special setting tool provided by the
manufacturer is used, the parameter can be set remotely by aligning
the actuator. It not only simplifies the setting work procedure,
but also improves the safe operation of the equipment, especially
those places that require explosion-proof;
(2) Rich online display functions. The use of liquid crystal
display technology, the use of built-in liquid crystal display
board, not only can accurately display the valve open and close
status and normal valve opening, and in the parameter setting or
actuator failure, but also can display important information;
(3) Perfect self-diagnosis and protection function. It can diagnose
the servo motor overload, overheating and the state of the power
supply online, and can automatically identify the phase of the
three-phase power supply. In case of emergency, the actuator can
maintain the position or run to the pre-set safety position;
(4) Advanced control functions. It adopts computer technology and
designs advanced automatic following control technology as one of
its standard functions. The response speed of the actuator is
proportional to the deviation size of the actual requirement, that
is, the so-called "variable speed control", which greatly improves
the response quality of the actuator;
(5) Strong field adaptability. The whole machine design has IP54
level protection capability, and the actuator internal and external
signal port also adopts photoelectric isolation technology, which
improves reliability, especially the actuator internal control card
adopts shock-proof fixing method, all connectors are equipped with
"reverse buckle" to prevent loosening, and the building block
structure makes maintenance very convenient.
