Related introduction:

Skd-120 / F06 electric actuator is an imported technology

1、 Product overview
(1) It is an intelligent control system.
SD series intelligent motor actuator, on the premise of fully taking the advanced technology of similar products at home and abroad, according to the characteristics of China's industrial control system, uses modern single-chip technology to complete its functions with reliable pic-16c711 single-chip microcomputer as the core, and all kinds of functions are controlled by & lt; Software & quot; Program to complete.
(2) It is a control system with complete functions.
1. Off signal protection function: when the input signal is less than 2mA, it is regarded as off signal. At this time, the output shaft acts according to the preset state of the user. There are three preset modes: A, in situ, B, full open, C, full close.
2. Over current protection function: when the actuator is over-current, the control circuit of the machine will automatically close and the actuator will remain in place to protect the actuator and valve.
3. Dynamic electric braking function --- when the motor runs to the given value = feedback value, the output shaft will vibrate due to inertia. In this case, the & lt; Software & quot; The program sends out a dynamic electric braking command (that is, gives an instantaneous reverse current) to stop the sweeping mechanism immediately without idling oscillation, which greatly improves the reliability and stability of the automatic regulation system.
4. Upper limit and lower limit function --- according to the needs of the site, the angular stroke is within 90 degrees, and it is within the rated stroke range. The upper and lower limit can be adjusted at will, and the adjustable range is about 40%. When leaving the factory, the lower limit is set to 4mA and the upper limit is set to 20mA
(3) It is a control system with high reliability and stability.
The pic series single chip microcomputer has powerful function and high reliability. It integrates central controller ram, ROM and I / O port. Due to the elimination of external leads, the possibility of interference is almost zero. Compared with the similar products of conventional circuits, Ken has the advantages of compact structure, less components, small volume, convenient adjustment, low failure rate and high stability. In addition, because the MCU is a single byte instruction, the confusion between operation code and operation number is eliminated, and the stability is further improved. Otherwise, the program is burned in ROM, and the software design is improved; Watchdog & quot( The watchdog circuit works independently in the MCU, and is not affected by clock and circuit; Crash & quot; Therefore, this system is a very reliable system. In summary, SD series intelligent electric actuator is an advanced model with the level of 90's, which is an upgrade of traditional products.
2、 Main technical performance:
The following technical performance mainly refers to the proportional regulation type, and the following items 1, 2, 3, 4, 5, 6, 11, 12, 13 and 14 of remote control type and switch type are not involved.
1. Input signal: 4mA-20mA DC or 1v-5v DC;
2. Input channel resistance; 250Ω;
3. Number of input channels: 1 (3 in discrete form);
4. Basic error:±1,±2.5%;
5. Return difference: 1%, 1.5%;
6. Dead zone: 0.5-3% (can be set according to system requirements);
7. Damping characteristics: no swing
8. Power supply voltage: single phase 220 V (+ 10%, - 15%) 50 Hz±1%
Three phase 380V±10% 50Hz±1%
9. Working environment: temperature: integral - 10 - + 55 ℃; Split type - 25 - + 70 ℃;
Humidity:≤85%, the surrounding air does not contain corrosive substances;
10. Enclosure protection grade; Comply with gb4208 IP65 (i.e. rainproof and dustproof);
11. Off signal protection function: there are three preset modes: A, home position, B, full open, C, full close;
12. Over current protection function: for different models, the protection current value can be adjusted( Over torque protection switch in mechanical part)
13. Dynamic electric braking function;
14. Upper limit and lower limit function: within the rated travel range, the upper and lower limit adjustable range is about 40%( The mechanical part has travel control switch and mechanical limit switch
15. Working system; Reversible intermittent working system, connection duration rate 50%, connection times 1200 per hour.
