SD Series Bernard Electric Actuators
(1) The Bernard electric actuator is an intelligent control system. SD series intelligent motor actuators, under the premise of taking advanced technologies of similar products at home and abroad, according to the characteristics of China's industrial control system, using modern MCU skills to complete its function entirely by the reliability of the PIC-16C711 microcontroller. Controls and various functions are completed by "software" programs.
(b) The Bernard electric actuator is a fully functional control system. 1. Break signal maintenance function ----When the input signal is less than 2mA, it is regarded as a broken signal, and at this moment, the output axis will act according to the preset condition of the user. There are three preset methods: a, in situ, b, full open, c, full off. 2, over-current maintenance function ---- When the actuator over-current when the machine control circuit is actively closed, the implementing agency insists on the in situ, to maintain the implementation of agencies and valves. 3, dynamic electric brake function --- When the motor works to a given value = response value, due to inertial operation will make the output shaft vibration. 4, the upper limit and lower limit function --- According to the needs of the scene, the angular travel within 90 degrees, so that it is in the extra range of travel, the upper and lower limit limit adjustable at random, the adjustable range at 40%. At the factory, the lower limit is set to 4mA and the upper limit is set to 20mA.
(c) It is a highly reliable and stable control system.
The PIC series microcontrollers selected by the motor actuators are powerful and reliable. With the elimination of external leads, the effects of disturbances may be zero. Comparing with the similar products of the custom circuit, the utility model has the advantages of compact structure, convenient adjustment, low failure rate and high stability. In addition, because the single-byte instruction of the single-chip microcomputer for the motor actuator eliminates the confusion between the operation code and the operand, the stability is further improved. Therefore, this system is a very robust system. To sum up, Tianjin's Mai-Zhifu's SD series of intelligent electric actuators is a leading model with the level of the 1990s, and is a product of the upgrading of traditional commodities. Strong technical advantages. In addition, the service level of Tianjin Majyofu has always been widely praised by customers. Therefore, Tianjin Majyofu enjoys a high level of assessment among its domestic counterparts.
Dot peen marking works by electromechanically striking a carbide or diamond stylus assembly against the surface of a part to be marked.For example,dog tag engraver.The result is a succession of dots to create digits, text, logos, and 2D data matrix codes. Each such dot is the result of a pulsed current that runs through a solenoid, punches a magnet toward the surface, and subsequently returns the stylus to its starting position, awaiting the next pulse. Because each pulse occurs in only a fraction of a second, an entire 2D data matrix code, for example, can be completed in seconds (depending on the size).
Notable Characteristics:
Cost effective
Requires no consumables
High speed accuracy
Will mark any material (including hardened steel)
Compressed air is not required.
