USB Four(4) Relay Module,Board for Home Automation:
$31.98

This is USB controlled relay board with 4 SPDT relays. You may use it for simple ON/OFF switching electrical devices - home lights, DC motors, solenodis and others. It may help you building projects like robotics and home automation. Each such relay board requires one USB port. The more USB ports you have the more Relay boards you may connect. You may use it with our software - DRM (universal software for all our relay boards) or control with simple commands from command line promt. If you are software developer and need software example, please contact with us.

Additional Information

This is relay board with 4 SPDT Relays controlled from USB port of your computer. The main purpouse of this USB relay module is to help you building projects regarding robotics and home automation (domotic). You may control differenet electrical devices like home lights, DC motors, pneumatic cylinders, lasers and so on. Each such board requires one USB port. The more USB ports you have the more such relay units you may connect and control.

Each such usb relay board is shown as separate virtual com port (VCP) on your PC. The relay module outputs are controlled by FT245RL. It has 8 bit data output register (this device use only 4 of them). When data is sent to the register the outputs are set. If you are software developer - be sure \"Synchronous Bit-Bang Mode\" is selected! FTDI provides Bit-Bang Mode documentation. See this. The usb relay card can not be controlled directly via COM port - you need to download our DRM Software to control the device. The usb relay unit can not work without PC. Only one such device can be supplyed from single USB port. If you want to supply many such devices you need USB HUB with extra power supply.

DRM Software

Denkovi Relay Manager (DRM) is multiplatform software for easy controlling all kinds of Denkovi relay boards (USB,SNMP,TCP/IP)

CAUTION! Using of Denkovi Relay Manager (DRM) Software with devices which are not manufactured by Denkovi Assembly Electronics LTD is not allowed!

The item is supported by DRM Software. DRM Software will hep you to save money for expensive software and time in programming. It allows you to switch ON/OFF your devices at particular date and time, turn ON/OFF the relays with pulses or control them via specific sequence. If you have ordered at least one of our relay boards from this list you may turn your PC in powerful automation tool.

Multiplatform software: supported by Windows/Linux (ver. 2.0)
Control up to 32 relay boards
User-friendly intuitive interface
Save/Load file
Control mode: single and multiple setting of the relays
Single pulse with adjustable delay from the control mode (ver. 2.0)
Timer mode: create timer playlist for the relays
Weekly mode: each relay may be turned ON/OFF on each day of the week
Calendar mode: each relay may be turned ON/OFF on particular date at particular time
Pulse mode: each relay may work in pulse mode by setting duration for ON and duration for OFF. Adjustable number of pulses (ver. 2.0)
Each relay from each relay board can work independently in some of the five modes
Each relay board and each relay can be named by the user
Indicator panel
Auto load function - the last working file is loaded when DRM is started
Auto connect function - when the relay board is disconnected DRM will keep trying to find and when this is done, the relay board will be connected again
Auto start function - DRM software starts when the OS starts (currently this is not available for Windows 8 and Linux)
Auto set function - DRM will set the relays automatically when the relay board is connected
Possibility of DRM to starts when PC boots and continues to work from the last saved point

Denkovi Relay Command Line Tool

The main goal of this project is to help you to use our USB relay boards easily and without any specific knowledge how do they work. This tool is actually shell for all our USB relay boards and it does not matter which is the relay board, the command is the same. Just type one command and the the tool will set, get relay status or even will take temperature value from the board sensor (if any). It can be integrated in other software and you don\'t need to know much about how the USB relay board protocol. With this tool it is like a \"game\" and it takes literaly minutes to create for example PHP script and control the USB relay board from smartphone browser.

Typical applications for this software are:

Create desktop icons to turn particular relays
Create BAT/BASH files to make more complex logic (like timers for example)
The commands can be executed from PHP script
Control our USB relay boards from Android / iPhone mobile devices
The USB relays can be controlled from each software/platform which can run external executable files or commands in command line promt

Example commands:

LIST COMMAND - lists all devices connected to computer.

java -jar DenkoviRelayCommandLineTool.jar list

STATUS COMMAND - display relay(s) status(es).

java -jar DenkoviRelayCommandLineTool.jar DAE0006K 4 2 status

java -jar DenkoviRelayCommandLineTool.jar DAE0006K 4 all status

SET COMMAND - set relay(s) state(s).

java -jar DenkoviRelayCommandLineTool.jar DAE0006K 4 2 1

java -jar DenkoviRelayCommandLineTool.jar DAE0006K 4 all 0

java -jar DenkoviRelayCommandLineTool.jar DAE0006K 4 turn 1110

TIMER COMMAND - exectues time-critical operations. Well known fact is that every time when we run the command line tool the jvm is runned and this takes significant time. Many users contacted us with requests to execute timer commands for time-critical operations. That\'s why we added such command. It can perform single pulse, many pulses and even cycles with more complex sequences of pulses and every pulse can be with different time (in miliseconds). Please note the state bits must be equal to the relay numer!

java -jar DenkoviRelayCommandLineTool.jar id=1 4 timer 1,1111,10,0000,50,1111,25 //makes all relays ON for 10ms, all OFF for 50ms and all ON for 25ms

java -jar DenkoviRelayCommandLineTool.jar id=1 8 timer 5,11111111,10,00000000,100 //makes all relays ON for 10ms and all OFF for 100ms - 5 times

java -jar DenkoviRelayCommandLineTool.jar id=1 16 timer //makes first relay ON for 10ms and OFF for 1sec - 5 times
