Programmable controller
The WAGO Programmable Fieldbus Controller (PFC) offers a flexible interface solution for SCADA applications, particularly in the water/wastewater industry, due to its Fieldbus-independent architecture. The Ethernet PFC is a popular choice for SCADA applications because it easily connects with off-the-shelf Ethernet products, including switches and hubs. The controller, used with the company's slice I/O modules, provides serial communication in addition to analog and digital I/O signals.
