I. Product Overview
(A) it is an intelligent control system.
SD series intelligent motor actuator, with the full E took similar products at home and abroad advanced technology premise, according to the characteristics of industrial control systems, the use of modern chip technology to its fully functional by the reliability of PIC-16C711 microcontroller as the core to complete each kind of control, the various functions performed by "software" to complete the procedure.
(B) it is a fully functional control systems.
1, protection ---- off signal when the input signal is less than 2mA, deemed off signal, the output shaft by a user preset state action. Preset three ways: a, in situ, b, full, c, fully closed.
2, over-current protection ---- overcurrent when the actuator control circuit automatically turns off the machine, the actuator remains in place to protect the actuator and valve.
3, Dynamic electric braking function --- When the motor is running to a given value = feedback value due to the inertia of run-down operation causes the output shaft oscillation. In this case, issued by the "Software" program a dynamic electrical braking instruction (ie, given a momentary reverse current) line agencies to make sweeping immediately stop running, no run-down oscillation, which greatly improved the reliability of the automatic control system and stability.
4, the upper limit and lower limit function --- according to the site needs, rotary in the range of 90 degrees, which groups within the rated travel range, upper and lower limit ends freely adjustable, adjustable in the range of about 40%. At the factory, the lower limit is set to 4mA, the upper limit is set to 20mA.
(Iii) it is a high reliability and stability control systems.
The choice of PIC MCU, its powerful, high reliability. It combines central controller RAM, ROM, I / O ports in one. By eliminating the external lead, may be affected by interference is almost zero. Compared with similar products of the conventional circuit willing to have a compact structure, the use of fewer components, small size, easy adjustment, low failure rate, high stability. Another result of the microcontroller is a single-byte instruction, eliminating the confusion opcode and operand, and further improve the stability. Otherwise, the program is burned in the software design and increase the "watchdog" (This watchdog circuit in the MCU is working independently, free from clock circuit influence) in ROM eliminates the MCU fundamentally "crash "occurs, and therefore, this system is a very reliable system. In summary, SD series intelligent electric actuator is an advanced model of the 90s, is a traditional product upgrading products.
