12 Channel relay board

This product is currently out of stock and unavailable.

MODEL: N/A Category:


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, contractors 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 directly by micro-controller TTL logic as well). It can be used successfully for example with PIC,AVR,ARM micro-controller, Raspberry PI, Arduino outputs and other.


  • Power supply – 5VDC;
  • Current consumption – 1000mA (when all relays are ON);
  • 12 SPDT relays – JQC-3F/T73 DC5V or RAS-05-15 (depending on your choice during purchase)*;
  • Maximum switching current per single relay channel:
  • For relay type JQC-3F/T73 DC5V (7A / 250VAC, 10A / 125VAC, 12A / 120VAC, 10A / 28VDC);
  • For relay type RAS-05-15 (10A / 250VAC, 15A / 120VAC, 15A / 24VDC);
  • Contact type: Normal Opened (NO), Normal Closed (NC);
  • Screw terminals for inputs and outputs;
  • PCB parameters : FR4 / 1.5mm / two layers / metallized holes / HAL / white stamp / solder mask;
  • Extra PCB openings for better voltage isolation;
  • Doubled high current tracks;
  • Protection diode for each relay;
  • Input voltage: 3V – 30V (1.5mA max) must be given to the “In” to switch the relay ON;
  • May be controlled directly by TTL;
  • Green leds for relay status;
  • Red led for power;
  • Dimensions: 85mm / 225mm / 20mm;
  • Mounting holes diameter: 3mm;
