AEG controller German AEG model AEG price

The AEG controller is the core of the access control system, the system brain that manages entrance and exit channels. It has evolved from traditional door locks. The door controller is an access control product that integrates card reading and control, available in standalone and networked types. Simply put, the access controller is a machine that integrates the access control board and card reader; higher-end models also include a keyboard and display. It can be used as a complete access control system simply by connecting to a power supply. If a door uses card swipe for entry and button press for exit, the controller can connect to only one card reader per door; this is called a unidirectional controller. If a door uses card swipe for both entry and exit (an exit button can also be connected), each controller can connect to two card readers per door: one entry card reader and one exit card reader. This is called a bidirectional controller.

AEG controller classification

1) Non-networked door controller: a single unit manages one door. It cannot be controlled via computer software, nor can records be viewed; control is performed directly through the controller. Features include low price and simple installation and maintenance. However, records cannot be viewed. It is not suitable for locations with more than 50 people or frequent staff turnover (referring to frequent hiring and resignations), nor for projects with more than 5 doors. 2) Networked door controller: an access control type that can communicate with a computer, allowing direct management via software, including card and event control. Benefits include convenient management, centralized control, record viewing, and analysis of records for other purposes. Features include higher price and increased difficulty in installation and maintenance, but training is simple, and value-added services such as attendance tracking are possible. Suitable for projects with many people, high mobility, and many doors. 3) TCP/IP network door controller: also known as Ethernet networked access control, this is a networkable access control system that connects computers and controllers via network cables. In addition to all the advantages of networked access control, it offers faster speed, simpler installation, greater networking capacity, and the ability to network across regions or cities. However, equipment costs are high, and computer networking knowledge is required. Suitable for large projects, locations with many people, applications requiring high speed, and cross-regional projects.

AEG controller functions

1) Motion control: In the machining industry, programmable controllers are integrated with Computer Numerical Control (CNC) to perform motion control of machine tools. Many PLC manufacturers provide single-axis or multi-axis position control modules for driving stepper motors or servo motors. In most cases, the PLC sends data describing the target position to the module, which moves one or several axes to the target position. As each axis moves, the position control module maintains appropriate speed and acceleration to ensure smooth motion. It has been used in centerless grinding, stamping, segmented punching of complex parts, roll grinding, and grinding applications. 2) Timing control: PLC provides users with a certain number of timers and timer instructions. For example, OMRON's CPM1A allows each timer to achieve timing control from 0·1 to 999·9s or 0·01 to 99·9s. SIEMENS's S7—200 series provides timers with time base units of 0·1s/0`01s and 0·00s, achieving timing from 0·001s to 3276·7s. Timer duration can be extended in specific ways. Timing accuracy is high, and timer setting is convenient and flexible. PLC also provides high-precision clock pulses for accurate real-time control.

AEG controller wiring

Programmable controllers have 3 output types: relay output, thyristor output, and transistor output. Output terminal wiring is divided into independent output and common output. When the PLC output relay or thyristor operates, the two output terminals with the same number are connected. In different groups, output voltages of different types and voltage levels can be used. However, within the same group, outputs must use the same type and voltage level of power supply. Since PLC output components are encapsulated on the printed circuit board and connected to the terminal block, short-circuiting the load connected to the output components will burn out the printed circuit board. Therefore, fuses should be used to protect the output components. When using relay output, the magnitude of the inductive load affects the relay's service life; therefore, long relay service life is required.
