General information
Extension Module PCA-062A-E2 extends the functionalities of units where it is installed, by an additional,
digital port RS-485. It provides communication with different systems, including:
DCS
SCADA
PLCs
Fire protection
This port is galvanically isolated, which allows for connecting systems supplied from different power sources
with no need to use additional RS-485 line separators.
PCA-062A-E2 module is not a stand-alone device and is designed for use as a built-in component inside
other equipment.
