Pepperl+Fuchs offers a wide range of interface modules for connecting WCS read heads to standard interfaces. All available interface modules are compatible with read heads with the special RS-485 interface, and up to four read heads can be connected.
The following interface modules are available:
The proven WCS is also available for applications that require a safety level up to SIL 3/PL e. For this purpose, two safeWCS/PUS read heads are combined with the safe evaluation unit (Position Unit Safe, PUS). The safe evaluation unit acts as a safe gateway to the fieldbus: It processes the redundant signals from the read heads, creates a safe position value, and derives a safe speed value from it. It also transmits diagnostic data that is available as a basis for condition monitoring and predictive maintenance.
