The Relay Sub Board
PCB:
Info:
Attach this board to the Simplified I/O Interface Board
Use nine pieces of hookup wire (or a piece of ribbon cable) to connect corresponding points on the I/O Demonstration Board to the Relay Sub Board. Connect 12 volts DC (smoothed) to the power input points on the I/O Demonstration Board. Solder in as many relays as you intend to use, each with its associated LED, resistor and 1N914 signal diode.
Parts List:
8 (or less) 12 volt SPDT relays
8 x 3mm red LEDs
8 x 560 ohm 1/4 watt carbon resistors
8 x 1N914 (or similar) diodes
1 x PCB Relay Sub Board
