Designed for ease of use and rapid prototyping, the relay shield is one of those must haves. No more tinkering around, wires flailing everywhere, just plug in and put a line into your program that makes an out put go high. Yep that's it, just one line of code will turn it on. The easy screw terminals allow for AC or DC use.

• Supports any Arduino shaped board.
  
  
• Has very useful interior pads so you can easily hard-mod the board to suit any layout.
  
  
• Supplied with a Shrack T7NS5D4-06 relay.
  
  
• Pin compatible with the entire T7N range (5v,6v,9v,12v,24v & 48v) the power can be externally supplied if desired by removing a jumper link.
  
  
• Relay has 10 amp 240 VAC/28VDC contact rating.
  
  
• Onboard "in use" LED.
  
  
• Onboard transistor driver buffers for easy drive from any micro or TTL source (3.3ma MAX).
  
  
• Onboard back EMF protection diode.
  
  
• Useful tie wrap holes to strap connecting wires to.
  
  
• Stardard 16amp screw terminals.
  
  
• Simple to use, fully configurable just connect "input" to any pin on the micro/shield.
