Secure authentification and a simple utilization are the key features of components RX-4MHCS series from company Aurel. Using the KeeLoq technology from company Microchip, they represent a complete solution for a remote control and authentification.
Company Aurel with rich experience in the field of RF data transfer and production of thick-film technology circuits has incorporated into their products a modern technology KeeLoq (HCS). This way a whole line of products for a secure control (RKE-remote keyless entry) in the 433,92 MHz band arised. It consists of transmitters – keyfobs and receivers with a decoder. Low power consumption, high sensitivity and a high security thanks to a 64 bit crypting key (unique in every device) used to generate a 32-bit hopping code, provide an immediately usable solution for control of locks, gates and any other devices, where concurrently with the control function itself, we also need an authentification. The transmitted code changes at every sending and it never repeats, what eliminates an unauthorised access.
A receiving element is the RX-4MHCS module available in versions RX-4MHCS, RX-4MHCS/F (both with 4 output channels settable into a monostable- as well as bistable mode) and RX-4MHCS-4B (4-bit output, 12 channels). The difference between MHCS and MHCS/F is, that the „/F“ version enables to freely assign any output to any button (for example an output no. 4 to a button no. 1), while a version without an „F“ suffix will assign to the 1-st keyfob button an output no. 1, etc. Before using a keyfob + receiver set, it is necessary to program a receiver according to a simple procedure (without a computer) described in the datasheet. A great plus is a wide range of operating temperatures, enabling an outdoor use – after building into an appropriate enclosure. Receiving modules are also available as ready-made PCBs with 4 output relays in 2 versions – HCS-DEC-4 and HCS-DEC-4/F. HCS-DEC-4 modules are readily usable without any soldering or other HW development.
Transmitting elements are keyfobs with 1-12 push-buttons. On stock we keep 1-4 button versions, upon request we´re able to provide you a 6- and 12 -button version too. Receiving modules are able to operate with up to 10 keyfobs. As it is common, receivers and also transmitters (keyfobs) only cooperate if they are from the same producers, i.e. receivers can only controlled by Aurel keyfobs and similarly Aurel keyfobs can´t be used to control modules from other producers. Further information will provide you the datasheets at particular components. On stock we also keep many other RF modules from company Aurel.

LT series LED drivers with 10-100W power represent a complete solution with wide possibilities of control. Exceptionally narrow and slim design, remained even at high-power versions, provides a high flexibility of use.
Power supplies for LED lighting (so called drivers) are available from many producers, in a various qualitative level. Why to decide just for the LT series from German company Friwo? Here are few reasons:
- precise design, safe operation and a long lifetime
- voltage and current regulation in one device
- high efficiency and a possibility of dimming in a range of 0-100% directly via a CTRL pin
- modules are available in 10-100W power, with a possibility of customization by laser directly at production also available a module for dimming – so called DIMMbox, further expanding possibilities of control (switch, 1-10V, DALI) and with a possibility of synchronization with up to 1000 slave units
- very small cross section of modules (21x30mm, resp. 24x30mm at LT100) – applicable even in very tiny conditions
Wide control possibilities of LT series modules are perhaps the most interesting. Modules contain a galvanically isolated CTRL input, by which it is possible to switch on/ off the module without disconnecting from 230V mains. CTRL pin also serves for regulation of an output current. For this purpose, only one resistor (or a potentiometer) is necessary – connected between SEC+ and CTRL pins, with a value counted by a simple formula in the datasheet. The output current can also be controlled by an external voltage in the range of 0-1,8V connected to SEC- and CTRL, as well as by means of a PWM TTL (0/5V).
Further possibilities of control are provided by a standalone additional module DIMMbox. DIMMbox operates as an (almost) lossless PWM regulator with a MOSFET switched at f=600Hz. DIMM-BOX connected to any series LT driver enables to regulate an output current in a range of 10-100% or 0% (OFF) via a usual switch (switch-dimm“ mode), via a linear voltage 1-10V and also a DALI interface. DIMMbox tests after switching on, which of three methods of control is used and consequently accepts only signals from a given input – until switching off the module. DIMMboxes can be connected through SYNC inputs, ensuring the same level of dimming for all modules. Enclosed pictures will provide you the best idea about possibilities of connection.

New intelligent display eDIPTFT70 from Electronic Assembly provides all what its smaller relatives and something in addition – the size.
With the 7” size and an 800 x 480 pixels resolution, it can display a relatively considerable amount of information. Similarly like other member of family eDIP (eDIPTFT32 a eDIPTFT43), even eDIPTFT70 eliminates the need of demanding and time-consuming programming at pixels level.
All the control of the display is done on commands level, thus to display text, graphics and many other symbols is exceptionally easy and simple. Control by commands substantially accelerates development and shortens the time to market. At an application development it is possible to use predefined functions, symbols and geometric functions, bargraphs, frames, buttons and many other. In general eDIPTFT70 offers almost the same functions like other eDIPTFT family members, including almost immediate start within a few 1/10 of second.
Single +5V supply, analogue touch panel with a variable raster and software-dimmable backlight brightness contribute to the versatility of usage. In many of applications also 80 various short jingles for audio feedback can be useful. Even eDIPTFT70 contains 3 communication interfaces – RS232, I2C and SPI, that´s why it can be connected to virtually any device. Further information will provide you the eDIPTFT70 datasheet.

We introduce to you a modern communication converter intended for connection of industrial M-Bus devices to the Ethernet, using the LAN/serial interface module XPort.
The communication converter is used in industry and building automation for data acquisition from heat consumption meters, flow meters, power consumption meters etc. It supports a connection of 1 to 5 M-Bus slave devices and a bus with devices connected can reach up to a few hundreds of meters length, depending on a connection quality, communication speed and additional protections. Connection of the interface module with a PC application can be realized by a virtual COM port, or directly through a TCP/IP connection. Connection through a virtual serial port is suitable for older programs, suitable only for a serial communication interface. Configuration of the interface module is possible via a password protected web interface.
A construction of the interface module is based on practical experience from implementing of communication interfaces in an industrial environment. In order to reach a high reliability and immunity, the module has an above-standard protection against overvoltage. M-Bus port is resistant to a continuous shortcut, overload and it contains a filter increasing the resistance of communication to disturbances. M-Bus port is galvanic isolated from power supply, as well as from an Ethernet interface, to ensure a high overvoltage immunity and it prevents ground loops creation. A range of a DC and AC power supply has a wide range and the power supply port has an overvoltage protection, as well as a self-resettable PTC current fuse.. The module is in a robust aluminium enclosure, with a possibility of mounting to a 35mm DIN rail. For a simple assembly and replacement is the connection of leads realized by plug-in connectors. Operation statuses are indicated by six LEDs for a quick detection of an actual module status, its work and an indication of possible communication errors. The „overload/short“ LED diode differs two basic M-bus link error statuses. A shortcut is indicated by a continuous light and an overload by blinking.

The essence of a proper and long-term operation of every device, is to use reliable components. From this point of view, relays Fujitsu are a synonym of reliability and a long lifetime.
To use a classic electromagnetic relay or rather an SSR – that´s the question, which apparently can´t be answered expressly, but pros and cons of both technologies are well known and information are easily available. We described to you features of solid-state relays for example in the article „Semiconductor better than a conductor?“. On the other hand, classic electromagnetic relays are still perspective, their features are continuously being improved and modern relays surprise by relatively small dimensions. To advantages of electromagnetic relays belong a high resistance to various power peaks, overvoltages and other disturbances. Price is also the factor saying in favor of electromagnetic relays.
Fujitsu FTR-K1 relays are power relays with a low profile, reflecting long-term experience of company Fujitsu. FTR-K1 replaced the over 20 years used VSB series relay, with which it is pin-compatible. High switching (16A) and inrush (80A) current, isolation strength up to 10kV, coil wound with a class F wire (155°C), cadmium-free contacts and RTII sealing make FTR-K1 literally a universal relay. FTR-K1 series is available in various versions – for example with up to 120A inrush current (K1-KS), with a transparent cover (K1-RG) and also with tab terminals for a simple load connection in the application (K1T).
As a standard stock in our offer can be found types FTR-K1CK005W, FTR-K1CK012W and FTR-K1CK024W with 5, 12 and 24V coils and one change-over contact (1CO, SPDT). We´re also able to supply other versions upon a request. Detailed information will provide you the Fujitsu FTR-K1 datasheet.
