• 1 x WiFi 16 Relay Module, TCP/IP, UDP, Virtual Serial Port - DIN RAIL BOX
• DRM Software - Denkovi Relay Manager Software. CD is not included in the package but the software is available for download from this link

The main feature of Wi-Fi 16 Relay Board is that it can control electrical devices wirelessly

Easy access Wi-Fi 16 Relay Board via Internet and control electrical devices

Wi-Fi 16 Relay Board can be accessed via Virtual Serial (COM) Port

Wi-Fi 16 Relay Board can controlled by some of smartDEN Input Module's analog/digital/temperature inputs via Internet/Ethernet (box-to-box mode). Please check out our application note about this mode.

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

Nowadays there are lot of software applications still using/preferring serial port communications. One key feature of the module is that it supports Virtual Serial (COM) Port controlling of the relays. For example in Windows, controlling of the module is done via Virtual COM Port, shown in device manager, like in the screenshot bellow.

There are really lot of mobile apps capable to send TCP/IP and UDP messages. One such free app is Socket Control Widget for Android devices. It is simple and creates widget buttons on your screen where every button can control a relay(s).
