4 Channel relay board for your Arduino or Raspberry PI - 5V
A general purpose 4 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.
Rating:
- Brand: Denkovi Assembly Electronics ltd.
- Weight: 0.136 Kgs
Code: DAE-RB/Ro4-5V
Features
- Power supply - 5VDC;
- Current consumption - 350mA (when all relays are ON);
- 4 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 / 70mm / 20mm;
- Mounting holes diameter: 3mm;
- PCB dimensions - here;
*The difference between two types of relays (RAS and JQC) is that RAS relays can handle bigger amperage (15A max) while JQC can 12A max.

Add the relay board to your Arduino project
Above is given example for 2 relays only. You can supply either from external power supply source, either from Arduino (however you must consider the maximum allowed current draw from Arduino in this case)

Ordered and received 2 boards for my electric chair project ... These things are FABULOUS ! Input power is 5v and channeling 24v dc and 24v ac; Works GREAT ! Thank you very much for your attention to perfection in manufacturing such an excellent product to the public.
