Electrical valve terminal link

Festo's CPX terminal is an electrical peripheral device for valve terminals. Compatible with commonly-used fieldbus protocols and capable of being adapted to user connection concepts, it simplifies communication between sensors, valve terminals and the electrical controller level.

Depending on the system concept involved, it can be combined either with MIDI/MAXI valve terminals to provide a high degree of modularity for harsh environments or with CPA valve terminals subject to normal mechanical stresses, to provide optimum triggering of actuators.

The open design of the terminal allows it to fit quickly and easily into various kinds of applications.

It has a physically separate connection panel and electrical section. This separation allows permanent wiring while still permitting fast replacement of the electronics module and thus more efficient rectification of faults.

A memory facility allows the CPX to store the causes of the most recent 40 faults, with data on the start and end of these.

It can be used in conjunction with Festo's CP installation system to create decentral structures consisting of valve terminals, the CPX itself and a drive and thus achieve faster cycle times. A particularly practical benefit is the small amount of wiring work required - an important factor for users such as the food industry and process automation.
