With the Compact Controller 100, WAGO now offers a compact controller with integrated I/Os, which is specially designed for applications in the miniature control segment. WAGO thus optimally rounds out its automation portfolio below the proven PFC Series. Thanks to its design as a rail-mounted device (REG), the new controller can also be mounted in small distribution boards. The I/O unit is housed together with the controller in a compact enclosure and therefore requires no additional space. The wiring level is pluggable - this has advantages during installation and facilitates device replacement. The device operates with a real-time Linux operating system and supports common fieldbus protocols. The Compact Controller 100 can be freely programmed according to IEC 61131. Extensive IEC libraries and IEC macros simplify the creation of applications. Project planning is performed with the familiar software tools from WAGO.
