Functional safety up to SIL 3 in potentially explosive areas

The configurable safety modules of the PSRmodular XC product family from Phoenix Contact have been certified for use in potentially explosive areas. This extends the range of applications further.

The PSRmodular XC product family is designed for use in extreme ambient conditions. With the easy configuration, safety-related applications up to SIL 3 and PL e can be realised. The modules in the XC series already had an extended operating temperature range of up to 70°C and special corrosion protection with an additional conformal coating on the printed circuit board. The modules can now also be used in zone 2 (ATEX) and Class I zone 2 (HAZLOC) hazardous areas up to temperature class T4. The XC portfolio comprises a total of five modules, particularly for process engineering applications.
