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.
