redwolf — Mon, 23 May 2016 12:24:04 +0000

MOPED – electric multi-turn actuator

Usage

Electric multi-turn actuator MOPED are designed for shifting valves and/or other elements for which they are suitable with their reversible rotary motion. Other using than that for controlling valves should be discussed with the manufacturer. The actuators can operate in circuits of remote control. The actuators can also operate in circuits of automatic regulation with the regime S4 – 25 %; 1200 h-1.

Description

Electro-mechanical control board is replaced with the electronic system DMS2 or DMS2 ED. Both systems scan position of the output shaft and torque of the electric actuator by contact-free magnetic sensors. The sensor of the output shaft position is absolute and does not require any backup power supply in case supply voltage is disconnected during operation of the electric actuator. Both systems can be set and monitored by a computer with controlling programme or manually without a computer.

The more simple system DMS2 ED substitutes electromechanical parts and/or provides for controlling the electric actuator by input analog signal as in the version Control.

The system DMS2 enables the electric actuator to be used for two-position and three-position regulation or to be connected to the industrial bus bar Profibus.

MOP – electric multi-turn actuator MOP

Usage

Electric multi-turn actuator MOP can be fitted with a position regulator, reversing contactors, overcurrent motor protection and the BAM electronic brake. They can be used to adjust control devices working in control systems, depending on the value of analogue input signal of the position regulator. They can also be equipped with reversing contactors only or with reversing contactors and the BAM electronic brake.

Description

The MODACT ® MOP actuators have been designed for changing position of control devices by reversing rotary motion (e.g. slide valves and other devices for which they are suitable in their characteristics). A typical example of application is remote two-position or multi-position control of devices which are required to close tight in their end positions.

Electric linear actuator MTPED

redwolf — Mon, 23 May 2016 12:07:58 +0000

MTPED – electric linear actuator

Usage

Electric linear actuator MTPED is used for remote two-position or three-position control of valves by reciprocating linear motion. The actuators can also be used for other devices for which they are appropriate due to their performance and parameters. Using in special cases should be discussed with the manufacturer.

Description

The MTPED actuators are based on MODACT MON actuator series. Moreover, they are designed with linear transmission unit for converting rotary motion into linear motion. An asynchronous motor drives, via a geared countershaft, the sun gear of a epicyclic gear unit enclosed in the supporting actuator box (power transmission). In the mechanical power control mode, the crown gear of a planet epicyclic gear unit is held in steady position by a self-locking worm gear drive. Alternatively, the handwheel, connected with the worm allows manual control to be accomplished even during motor operation without any risk of operator’s injury.

The actuator is controlled by built-in electronic circuits scanning the state of the actuator output shaft, output shaft torque, temperature of electric motor, value of supply voltage, and input signals. They are evaluated by the control program which, depending on pre-set parameters, controls output signals – state of output contact, output analog signal, control of electric motor, data communication with the superior control system.

The control elements are accessible after taking off the control box lid. For the actuators designated MTNED and for the actuators designated MTPED, the electric motors used have protective enclosures IP67. The complete actuator has the protective enclosure according to the electric motor used.

Electro-mechanical control board is replaced with the electronic system DMS2 or DMS2 ED. Both systems scan position of the output shaft and torque of the electric actuator by contact-free magnetic sensors. The sensor of the output shaft position is absolute and does not require any backup power supply in case supply voltage is disconnected during operation of the electric actuator.

Both systems can be set and monitored by a computer with controlling programme or manually without a computer. The more simple system DMS2 ED substitutes electromechanical parts and/or provides for controlling the electric actuator by input analog signal as in the version Control. The system DMS2 enables the electric actuator to be used for two-position and three-position regulation or to be connected to the industrial bus bar Profibus.
