The second version of our popular USB 4 Relay Board with several improvements. It comes with MCP2200 chipset, 4 SPDT Relays each rated with up to 10A, relays states saving in internal EEPROM and improved USB interference resistance. Suitable for home automation applications, hobby projects, industrial automation. The free DRM software allows to control relays manually, create timers (weekly and calendar) and multivibrators, use date and time for alarms or control from command line. We provide various software examples.

Chipset
The relay board chipset is MCP2200. We decided to develop such relay board because as per our tests MCP2200 has some more advantages with other USB-UART chips and one of them is that it is more reliable against USB interference and this is critical on every USB relay board.
The four relays are mapped in the following way with MCP2200 i/o lines:
The four I/O lines are mapped in the following way:
Compability
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.
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:
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 00012345674v2 2 status
java -jar DenkoviRelayCommandLineTool.jar 00012345674v2 all status
SET COMMAND - set relay(s) state(s).
java -jar DenkoviRelayCommandLineTool.jar 00012345674v2 2 1
java -jar DenkoviRelayCommandLineTool.jar 00012345674v2 all 0
java -jar DenkoviRelayCommandLineTool.jar 00012345674v2 turn 1110
TIMER COMMAND - execute time-critical operations. Well known fact is that every time when we run the command line tool the jvm is being run 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 milliseconds). Please note the state bits must be equal to the relay number!
java -jar DenkoviRelayCommandLineTool.jar id=1 4v2 timer 1,1111,10,0000,50,1111,25 //makes all relays ON for 10ms, all OFF for 50ms and all ON for 25ms
