Remote control devices
Controllers are used to simultaneously switch in the last few quarters have sent the message, as well as for start, stop and control of electrical machines
Magnetic starters and contactors are designed for remote start-mediocre without network connectivity, Stopping and reversing the three-phase Asa-hronnyh motors with closed rotor briefly at a voltage to 660 V AC 50 and 60 Hz. In agriculture-use basis or a series of starters: PML, PME, PMA, PM and PAE contactors, KT5000, VP6000, KMY.

Contactor (eg series KMY) allow remote management circles lighting, to perform switching of three-phase capacitor and primary winding three-phase low-voltage transformers.
Magnetic starter is an electromagnetic device AC, magnesium-TNA system is divided into two parts: Fixed to Z - shaped anchor mounted on flexible basis, and a moving system with contacts for switching power circle. Office of magnetic actuators is done with the help of my bahatovytkovoyi coil, which is located on the middle core non-movable part III - a similar magnetic system.
The principle of: When current flows through the coil under the influence elektroma-hnitnoho field pulling the coil draws the anchor to the core and moves along with moving the system placed on it by moving contacts, which close the co-lo power settings.
It closed magnetic system and overcome resistance reverse springs and spring contact bridges. To prevent detonation under heavy cage aluminum rings that press-fitted in the pole nakone-owl fixed part of the magnetic system.
Contacts magnetic starters for other purposes are classified as main and auxiliary contacts. The main contacts are intended to control plant that connect to the network and designed for its rated current, auxiliary contacts appointment to control pilot lights, electrical, we relay coils and magnetic starters are designed for smaller currents. Help of international contacts in the nature of the spread of locking and rozmykayuchy. To control the magnetic starters are used push-button station. In shty-ftah (buttons) are located a contact group that opens the lock range and coil magnetic actuators.
Coil magnetic actuators operates reliably at a voltage of 85 ...105% Of the nominal voltage. By reducing the voltage below 35 ... 40% of the no-voltage starter minalnoyi excluded, while restoring the voltage to the magnitude-ing the nominal values ​​of inclusion does not, what is a mini-conservative consumer protection. If the voltage is quite disappears, then appears in this case prevents the starter samopryzvilnomu run vol-bers (zero protection). If magnetic starters supplied thermal relay, in this case provides consumer protection against overload.
In controlling the electrical circuits or control systems of micro-processor technology used intermediate relay series RPL at a voltage of 440 VDC and 660 VAC at 50 Hz and 60. Rated current of contacts 16
If necessary, increase the number of auxiliary contacts on each starter can set 2 and 4-pin set-top box (eg series ASV) or side console series PKB.
Pneumatic consoles delay time (eg series PVL) secured hear to have contacts with the delay time from 0.1 to 180 sec.
In order to limit switching overvoltages that arise when OFF-ing starters on reels administration produced Overvoltage surge arrester.
Operating position - mounting vertically conclusions co-carcasses up. Allowed deviation from the working position to 20  in any way.
