Profibus-DP Barrier / Segment Coupler

SC12EX

SC12Ex Segment Coupler

Intrinsic Safety Barrier for isolation between RS485 & RS485-IS
 
2 x RS485-IS for up to 62 additional modules or 31 modules in case of line redundancy

All segments are equal communication channels

Automatic baud rate detection (selection of baud rate via rotary switch)

Regeneration of amplitude and phase

Certified: Ex II (2) GD [EEx ib]

The SC12Ex coupler is capable of working with both lines of the intrinsically safe I/O system excom® (line redundancy). Thus, only a single device is needed to provide intrinsically safe separation and line redundancy.
The segment coupler SC12Ex is mounted in the non-hazardous area and features protection rating IP20.
The coupler supports use of a redundant power supply. The two operating voltage inputs are isolated by diodes.
