2、 Product performance and indicators
1. Product performance
Adopting large-scale digital integrated chips, with powerful functions and high precision levels.
Mechatronics design, small size and light weight.
Classic mechanical torque protection device, stable and reliable operation
The displacement sensor adopts a Hall sensor and digitally quantifies the pulse signal, so the basic error of valve positioning accuracy reaches level 1 accuracy.
The functions, parameter settings, debugging, and on-site electric operation of the actuator are all set through a handheld remote control, without the need to open the box cover.
Full Chinese and character display, menu style operation, easy to learn, understand, and operate.
Multiple protection functions, high reliability.
The Profibus DP redundancy protocol complies with international standards and supports DPV0 and DPV1.
Provide EDDL and FDT/DTM device descriptions.
