The electrical assembly diagram for the Desktop Industrial Automation Trainer is shown in Figure 5. The DC motor can be attached directly to the relay block terminal screws or a solderless breadboard If you are using the same switch from Newark that we used, refer to this wiring diagram. Pins A, B, C, and D are the common poles that will be hooked up to the 4-pin male Molex power Most rotary With a full 56 pin cable we know then we'll discuss how to wire it. Each leaf switch on the joystick or button has 3 leads: NO (normally open) NC (normally closed) and C (common) Wire the "C" The circuit shown in the diagram below uses a relay to switch 12V across a DC motor. To turn on the motor, the program writes a HIGH value to pin 3, which activates the optocoupler which in turn (8-10) 6mm tact switches - Digi-Key part # EG2495-ND. We'll use these for the eject buttons and other controls. Male headers - Digi-Key part #A26525-40-ND. This is a 80 pin male header component If the main circuit's Vcc falls below Vbat, the RTC switches automatically over to a low-power battery backup mode. The backup battery is usually a 3v coin cell battery connected to PIN 3 and .
It's barely a circuit, more a wiring diagram for the various modules. Power comes in from either a battery or fixed supply, is fed to the high-current motors and the voltage regulator, and the output .
