Relay-Bee Home Automation AdaptorHome automation and robotic control made easy
The simplest way to get started in home automation.





    Simply connect the Relay-Bee to any free USB port to give immediate access to 7 sets of SPDT (changeover) relay outputs plus an additional 7 DC switches.
   The relay outputs are rated at 250vAC/110vDC Maximum Voltage and 6A Maximum current. All three contacts for each relay are accessible via screw terminals and there are on-board LED's to indicate the on/off status of each relay.


    Supplied with the Relay-BEE is BeeStep14 control software.  This is a full editing suite for creating your own switch sequencer programs.  Simply enter your pattern of On/Offs and the duration of each step for up to 10,000 steps followed by RUN to  watch your connected devices respond according to your programmed sequence. No computer programming knowledge is required.
      Relay-BEE is designed to be simple to use even for the complete beginner with full instructions on how to connect devices and create your switch sequences. A standard USB lead (not included) is needed to connect the Relay-BEE to your computer .
   For the more advanced user who wants to write his own programs for the RelayBee a DLL is provided, greatly simplifying the process. This DLL allows user programs written in a wide range of languages (eg C, C++ , Visual Basic etc...), to have easy access to it's facilities. This gives the programmer simple to use functions like InitMbee() and SetOutputs(outputs) rather than having to address the tricky USB comms protocols. The application software and DLL for the Relay Bee are identical to that used in the MiniBee. This means that for current users of the MiniBee their programs are code compatible with the relay bee, offering an easy upgrade path for those requiring greater power handling capability and/or isolation. For more information on writing visual basic programs for Relay-Bee see the programming page for the MiniBee which is at....

WARNING: The Relay-Bee adaptor board is fitted with relays that are capable of switching high voltages and high currents. Use of the Relay-Bee in any intended application needs careful design paying particular attention to the safety aspects including a suitable enclosure. i.e. if used for high voltages, it should not be used simply as supplied. No provisions have been made to safeguard the potentially dangerous exposed relay terminals on the board or the board tracks connecting them. If you intend to switch high voltages or currents in your application then you need to address this issue. If you have any doubts about how to use the board safely then you should consult a qualified electrician.
