It is a control system typically also AC and DC voltage at various levels. Control cabinets are often associated with single-phase AC at 220/440/550V or two-phase AC supplied 220/440Vac or three-phase AC 330/550V. This achievement must be based on a lower level of voltage and DC-reducing control.

110Vac is common in North America, and 220Vac is in Europe and the Commonwealth spread. It is also common for supplying a control panel with a voltage higher than with other devices such as motors.

An example of a system for a DC motor in V of A diagram of motor control (Note: the symbols are described in detail below). Dashed lines indicate acquired on a single component. This system uses 3-phase AC power (L1, L2 and L3) connected to the terminals. The three phases are then connected to a power switch. Subsequently, all three phases of a motor starter that three contacts, M, and three thermal overload relays (switches) has delivered. The contacts, M is from the coil, M. The output of the controlled starter goes to a three-phase AC motor.

Power is supplied by connecting a step down transformer for the control electronics by connecting to phases L2 and L3 supplies. The lower voltage is then in power in order to provide the bars on the right and bottom left of the scale. The rail is also neutral ground. The logic consists of two buttons. The start button is normally open so that if something is not the motor can not be started. The stop button is normally closed, so that if a wire or a connection to close the system secure. The system controls the motor starter coil M, and uses a contact parts for the starter, M, the stater motor seal.

The diagram also shows the numbering for the wires of the device. This is for industrial control systems that can contain hundreds or thousands of wires is essential. These tools are often specific numbers for each plant, but there is help make wire labels that appear in the control cabinet will last.
