Technical Parameters

Box size, mm 210 x 85 x 58
Box weight, g 420
Power supply voltage,VDC 12 or 24 (depends on the model) ±2
Maximum current consumption at 12VDC (when all relays are ON), mA 600
Maximum current consumption at 24VDC (when all relays are ON), mA 400
Operating temperature range, °C 0 to 70
Relays JQC-3FC/T73 maximum switchable current / voltage 7A / 250VAC, 10A / 125VAC, 12A / 120VAC, 10A / 28VDC)
Relays RAS-12-15 maximum switchable current / voltage (10A / 250VAC, 15A / 120VAC, 15A / 24VDC)
Relays RAS-24-15 maximum switchable current / voltage (10A / 250VAC, 15A / 120VAC, 15A / 24VDC)


Please note the product does not come with power supply adapter that you may need. We offer such suitable 12V adapters with plug-in outlet for your country on this link:

The difference between the three types of relays is that JQC-3FC/T73 and RAS-12-15 requires 12VDC power supply and RAS-24-15 requres 24VDC power supply. JQC-3FC/T73 relays can handle max 12A/120VAC and RAS-12-15 / RAS-24-15 can max 15A/120VAC.


Application Examples

  • Remote control of electrical appliances;
  • Industrial automation;
  • Home automation;
  • Restart computers remotely;
  • Garden irrigation applications which requres powering on/off upon certain time without computer.


Easily access SmartDEN IP-16R via internet or LAN and control appliances remotely for Home Automation and Industrial Automation applications.

SmartDEN IP-16R supports up to 30 schedule events for controlling appliances without connection with computer. It is possible to set ON/OFF event upon minute, hour, day of week or certain date. For more information please take a look into the documentation.
