Eltako controller, German Eltako model, Eltako price

The Eltako controller is the core of the access control system, acting as the system brain that manages entry and exit channels. It has evolved from traditional door locks. The door controller is an access control product that integrates card reading and control functions, available in both standalone and networked versions. Simply put, an access control controller is a device that integrates an access control board and a card reader; higher-end models also include a keyboard and display. It can function as a complete access control system simply by connecting to a power supply. For a single door where entry is via card swipe and exit is via button press, the controller can connect to only one card reader per door; this is called a unidirectional controller. For a single door where entry is via card swipe and exit is also via card swipe (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.

Eltako controller principle

For all electronic devices with microcontrollers, the operating principle naturally depends on the specific device. However, its most basic principle is: 1) receiving information from the outside world via input interfaces and storing it in memory. This information mainly consists of two parts: data from sensors such as temperature and pressure sensors, and manual input from human intervention, such as switch or button operations. 2) The central processing unit in the microcontroller performs high-speed arithmetic processing on the input data according to the program. 3) The results of the arithmetic processing are sent via output interfaces to control actuators, such as relays, motors, and lamps. This process repeats continuously, meaning the microcomputer in the system constantly monitors various information and promptly performs different processing tasks to ensure normal system operation.

Eltako controller functions

1) Motion control: In the machining industry, programmable logic controllers are integrated with computer numerical control (CNC) to perform motion control for 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 more 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 blanking of complex parts, roll forming, and grinding applications. 2) Timing control: The PLC provides users with a certain number of timers. With timer instructions configured, such as those in OMRON's CPM1A, each timer can achieve timing control from 0·1 to 999·9s or from 0·01 to 99·9s. SIEMENS's S7-200 series offers timers with time base units of 0·1s/0`01s and 0·00s, enabling timing ranges 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. The PLC also provides high-precision clock pulses for accurate real-time control.

Eltako controller wiring

Programmable logic 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. Different groups can use output voltages of different types and voltage levels. However, outputs within the same group must use power supplies of the same type and voltage level. Since the 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 operating life, so a long relay operating life is required.
