Denkovi Assembly Electronics ltd.

This is Four Channel relay board controlled by computer USB port. The usb relay board is with 4 SPDT relays rated up to 10A each. You may control devices 220V / 120V (up to 4) directly with one such relay unit. It is fully powered by the computer USB port. Suitable for home automation applications, hobby projects, industrial automation. The free software DRM and DRMv3 allows to control relays manually, create timers (weekly and calendar) and multivibrators, use date and time for alarms. We developed also command line tool utility for controlling the relays. We provide software examples in Labview, .NET, Java, Borland C++, Python.

SmartDEN IP-16R is a LAN relay module with 16 SPDT relays for remote control with integrated web server for set-up, snmp-v1 and http get, xml and json requests support for embedding in other systems. The built-in real time clock allows to organize schedule stand-alone work without connection to computer. Suitable for industrail and home automation applications, irrigation systems and network watch-dog systems. Works with Home Assistant, Domoticz and OpenHAB home automation systems as well as with Node-RED IoT platform. Supported by DRM and DRMv3 Software, DAE-aModules Android App and DAE-iModule iOS App plus many source code examples. This is the PCB version.

Five channel Ethernet relay card based on DAEnetIP4 snmp IP controller. Additionaly it supports 8 digital outputs, 8 digital inputs, 8 analog inputs plus 2 PWM outputs. Control it from web browser, DRM and DRMv3 software, command line tool, free Android and iOS App and others. Flexible for integration. For developers we provide software examples in Java, .NET, Labview, PHP. Works with Home Assistant, Domoticz and OpenHAB home automation systems as well as with Node-RED IoT platform. The relay card can be used for home automation, industrials, sensor monitoring or embedding in larger systems. This is the PCB ONLY version.

A general purpose 10 SPDT channel relay board (power supply 12VDC) for switching high-current electrical loads (both AC and DC) siuch as motors, lights, pumps, contactors and more.  With this relay board, any logic-level signal from 3V up to 30V can be used to activate a relay (it may be controlled direclty by microcontroller TTL logic as well). It can be used successfully for example with PIC,AVR,ARM microcontroller, Raspberry PI, Arduino outputs and other.

Set of IP SNMP controller and Eight channel Relay board. The system may be controlled by WEB browser, windows application, Android software and SNMP commands.

USB relay board with four channels and connected TCN75A temperature sensor to it.. The relays can handle up to 7A(10A) at 220VAC/120VAC and the sensor can measure temperature from -40 C up to +100 C with accuracy +-0.5 C (typical) and +- 3 C (max). The software we provide makes this usb relay card ideal for applications like temperature monitoring (USB thermometer), temperature loging or simple usb thermoregulator. Supported by DRMv3

smartDEN IP-Maxi is an Ethernet module (IP controller) that can be used in a wide range of remote sensors monitoring, home automation control, environmental monitoring and data-acquisition applications. Thank to its multi-channel design (8 digital inputs, 4 analog inputs, 4 temperature inputs, 8 SPDT relays and 2 analog outputs) this device can perform simultaneously a variety of measurement and control functions. The Web interface allows users to configure the smartDEN IP-Maxi, as well as to monitor/control input/output channels. Supported by DRMv3 Software. smartDEN IP-Maxi provides both SNMP and XML/JSON interface for integration with third-party developed applications. Works with Home Assistant, Domoticz and OpenHAB home automation systems as well as with Node-RED IoT platform.

A general purpose 12 SPDT channel relay board (power supply 5VDC) for switching high-current electrical loads (both AC and DC) siuch as motors, lights, pumps, contactors and more.  With this relay board, any logic-level signal from 3V up to 30V can be used to activate a relay (it may be controlled direclty by microcontroller TTL logic as well). It can be used successfully for example with PIC,AVR,ARM microcontroller, Raspberry PI, Arduino outputs and other.
