About the PLC black filled icon
Inside a circular frame sits a boxy control unit: a rounded display panel lettered PLC, two small rectangular terminal blocks flanking a round indicator lamp beneath it, and a short pedestal stand with a slot. It stands for programmable logic controllers, factory automation and machine control. Use it in SCADA and HMI interfaces, industrial automation product catalogs, engineering diagrams, PLC training material and control panel documentation.
The unit is centered and slightly wider than tall, with the lettering carrying most of the visual weight so the device is identifiable even without context. The enclosing circle matches other badge-framed technology glyphs in the library and pairs with sensor, relay and servo motor icons. Use it at 32 px or larger, otherwise the PLC lettering closes up.
This is the solid black filled version of the plc icon: a bold silhouette that reads clearly at 16-24 px and on dark or busy backgrounds, and prints well in one colour.
