Basic electrical design of a PLC panel (Wiring diagrams) | EEP A control system of a PLC panel will normally use AC and DC power at different voltage levels. Control cabinets are often supplied with single phase AC at 220/440/550V, or two phase AC at 220/440V AC, or three phase AC at 330/550V. This power must be dropped down to a lower voltage level for the controls and DC power supplies. 110Vac is common Control Panel Build Series Part 17: Wiring Power Distribution Click to view7:41Electric Brewing Supply - Panel Build Part 1 - Panel layout and 220V wiring - for electric brewing - Duration: 11:44.

It shows the components of the circuit as simplified shapes, and the power and signal connections between the devices. A wiring diagram usually gives information about the relative position and arrangement of devices and terminals on the devices, to help in building or servicing the device.
