USB Four(4) Relay Module,Board for Home Automation
General description

Brief description:

This is USB controlled relay board with 4 relays RAS-05-15 (each can handle 10A). 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). If you are developer and need software example, please contact with us.

Characteristics:

4 Relays RAS-05-15. Datasheet - here
Relay parameters: 5V / 72mA, 15A/24VDC (120VAC), 10A/250VAC
PCB parameters: FR4 / 1.5mm / two layers / metalized holes / HAL / white stamp / solder mask / еxtra PCB openings for better voltage isolation / doubled high voltage tracks
Power Supply - from USB port
Current consumption - 400 mA
FT245RL. Datasheet - here
Led for each relay output
Size - 77mm x 56mm x 17mm
Supported by DRM software (Windows 32/64 and Linux 32/64)
Command line open source application for Linux available
Software examples: VB6, BCB6, Java, .NET 2010 Express, LabVIEW Please contact with us for download.

DRM Software - Denkovi Relay Manager Software. CD is not included in the package but the software is available for download from this link

Software development

Each such device is shown as separate virtual com port (VCP) on your PC. The relay board 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. Also the baudrate must be set with high value - 921600 (to avoid the latency if any) See this. The board can not be controlled directly via COM port - you need to download our DRM Software to control the device. The unit can not work without PC. Only one such device can be supplied from single USB port. If you want to supply many such devices you need USB HUB with extra power supply.

DRM Software 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 supported by 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
