The MicroSmart FC6A series has two CPU options: Plus and All-in-One. The All-in-One type features an integrated serial port and an RJ45 Ethernet port capable of expanding up to 520 I/O, while the Plus type has a twin RJ45 Ethernet port, embedded web server functionality, and the capacity to expand up to 2060 I/O.

Powerful micro PLC with up to 520 digital I/O and 126 analog I/O is the FC6A All-in-One CPU. There are three variants that each have a 24V DC or 100-240V AC input power. The 16 I/O model features 7 relay or transistor outputs and 9 inputs. The 24 I/O model features 10 relay or transistor outputs and 14 relay inputs. The 40 I/O model features 16 relay or transistor outputs and 24 inputs. Every model also comes with a built-in 0-10V DC analog input. One plug-in analog cartridge may be accommodated by the 16 and 24 I/O variants, while two can be by the 40 I/O model.
