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.

A general purpose 8 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.

Ethernet SNMP and WEB relay I/O module based on DAEnetIP1 with 12 SPDT relays (up to 15A), 8 ADC inputs (0-10V) and 8 digital inputs (0-12V). Suitable for controling electrical devices and monitor different sensors from the ethernet network. It can be accessed locally (LAN) or remotely (Internet,WAN) via web browser, computer software, android/iOS smartphone. We provide various software examples for easy integration in your code.

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.
