Phoenix Contact PROFIBUS PA I/O gateway

Click2Contact

Whether it is called a multiplexer or a gateway, users will find several applications for the PROFIBUS PA device from Phoenix Contact. It comes in five profiles and bundles simple digital and analog inputs and outputs into one PROFIBUS PA telegram. Users can integrate analog and digital I/Os into the system via the PA head station, Radioline I/O modules and the four-channel NAMUR input module.

Since all signals are transferred to the control room from the field via PROFIBUS PA, users can perform the entire installation with standard PROFIBUS PA cables. The five application-specific head stations allow simple implementation in the field. No additional software is necessary due to the preconfigured head station.

The five head stations with specific function sets also use the regular RADIOLINE expansion modules. The entire assembly is IECEx/ATEX Zone 2 compliant, and the head station requires no programming. Setting up the communication telegram in this system is done from the DCS or PLC controller, and modules can be replaced without interfering with the software or configuration. Other advantages include inherent scalability and the ability to integrate into a host system via an EDD or GSD file.
