Programmable Relay operated via the Internet, LAN, Cell Phones with Android OS, Encrypted Data Transmission, built-in Astronomical Timer. How to wire your home for Automation: http://www.elkom.com.tw/m/PLC2011_circuits.pdf
PLC2011A0 is more than just a simple Programmable Relay or a Programmable Logic Controller (PLC). It is a PLC controller operated through the Internet and Cell Phones and with unique security systems.
PLC2011 is a perfect substitute for expensive and complex Intelligent Home / Buildianng Management Systems. Instead of costly touchscreens you can use your cell phones, tablets and computers. No other devices are needed to build your own intelligent installation and control it from any place in the world thanks to a encryption system protecting the sent commands. One relay replaces a ten times more expensive "system" and at the same time is ten times easier to install and operate.
Some of the devices characteristics:
- remote control of electrical circuits and devices through the Internet in a manner ensuring absolute safety
- automatic operation, without the user's constant supervision
- RS232 TTL 0..5V with 32 bytes of Tx and Rx FIFO
- strong encryption - AES256
- hash function - SHA256
- encryption time stamping
- 6 optically isolated binary ( two state ) inputs ( 110-230VAC or if requested 12-24VDC )
- 7 relay outputs with both NO and NC connectors
- the mutual relation of phases, frequencies and amplitudes of sinusoidally variable voltages is not important
- Ethernet 10Mb full duplex interface
- USB 2.0 interface
- RS232 TTL interface for communication with extensions
- advanced operating software for constant monitoring and control
- built-in WWW server
- multichannel astronomical clock with timer and a night break
- real time clock
- automatic time synchronization with the Internet via NTP
- energy consumption of ca. 1W with relays off + ca. 0.45W for every relay
- built-in gel battery charger
- connector for a gel battery
- software in English, German
- manual in English
The device was designed with a lot of attention put on safety. An advanced, military strength cryptographic system protects data from being intercepted during transmission and used again, prevents unauthorized access to the device by people trying to impersonate the rightful user. From now on you can safely open gates or roller shutters even from the other side of the planet without fear that an intruder will intercept the Internet transmission and use it to break into your house, open your gate or roller shutters or disarm the alarm. The only thing you cannot do via the Internet is change the password to the device. The password can only be changed when you connect the device to your computer with an USB cable and enter the PIN code.
Used security technologies:
- Hash function SHA-256 - http://en.wikipedia.org/wiki/Sha256
- Symmetrical encryption with the AES-256 algorithm - http://en.wikipedia.org/wiki/Aes256
- Cryptographic time stamping
The device has all interfaces used for communication and no additional cords or adapters are required. Standard computer network wiring is enough for the device to work properly. This type of functionality is not found in any other device available on the market. An ethernet cable is not included in the package.
Easy Programming and operation:
This is not a typical programmable relay. You do not program it in the STL language or build a LAD ladder.
This is a relay programmable by picking a function from a list, intended for people who do not have time to learn how to program relays but who need to carry out a quick modernization of their electrical installation, who want to equip it with additional logical functions, temporal dependencies between circuits but first and foremost who want to control the installation using the Internet without having to worry whether the transmission is safe.
Programming the device is so simple that it does not require any tutoring or basic theoretical knowledge. It will only take you a few minutes to set up first your functions without anyone's help.
Where you can use PLC2011:
- gates, doors - to control entry or garage gates at your house, shop, company etc. using PC or cell phone
- to control roller shutters, motors, exterior and interior lighting ( Astro timer option )using PC or cell phone
- heating - to control how your boiler room works, turn on and off furnaces, boilers, pumps
- air conditioning
- watering gardens, pitches, fields, all kinds of green terrain e.g. right after sunset or just before sunrise (controlled with the Astro timer)
- housing cooperatives – administrators may control a group of relays and regulate lighting or watering of mutual terrain
- to control electric devices by yourself through logical functions, timer and the Astronomical Clock
- control of the relay over the Internet, LAN, cell phones with Android OS
- supervision and status check using any cell phone with web browser
- cooperation with access systems, alarms
- remote starting, shutting down, and restarting of computers, network devices
- starting power-generators, ATSE
- multi-way ( staircase ) switches based on the time of day and night ( Astro timer )
- counters -counting people, employees, clients coming in and going out
- counting electric energy consumption
- save money - economically efficient control over lighting and heating, keeping them on only when necessary
- equipping installations and devices with a safe, Internet control system
- control over water pumps, septic tanks, machine security
- various applications in industry and residential buildings BMS
- whenever there is a need of remotely controlling and monitoring something this device will fulfill your needs
- various other applications that depend on user's needs, ideas and imagination
Contents of the package:
USB cable for connecting the device to a computer ( 1,8 m )
15V Power Supply Unit
CD with drivers, the user's manual and basic version of the software
The software, firmware, USB drivers and the manual are constantly modified and updated. The ones you receive on your CD may be older than those currently available on the manufacturers website. Please always download the newest versions from the Internet.
The PC software was tested and proved for Apple Macintosh under Windows in the VirtualBox. It will not work in the native mode but will work in the virtual machine on every Intel based Mac.
Please remember that new software may not always want to cooperate with old firmware written into the device. Please read the readme.txt files every time and update the firmware when required.
You do not need to monitor the device after you place it in your electrical box. You operate it via the Internet.
New features of the software for Android and PC: Encryption of short messages. It can be used to encrypt and decrypt e-mail, SMS, short messages and the content of any plain text file up to ~50kB. It can be encrypted on the PC and decrypted on Android, PC to PC and Adroid to Android.
Plain text → (password+salt) → SHA-256 → xor random numbers → AES-256 → cipher text → Base64 encoded text.
