station (AT) PT2002-A1
PCA2011-A1 and PCA2018-A1 (3) provide isolated DC 24 V. A short circuit
outside of the cabinet has no impact on the whole cabinet.
The PCA2001-A1 (4) detects a ground fault on the 24 V wiring to PT2001-A1 and
PT2002-A1.
Each 24 V wiring (7) to PT2001-A1 and PT2002-A1 is installed with a 1 A fuse (5).
It ensures that a short circuit on one 24 V wiring has no impact on the other.
In high reliable life safety systems, use a redundant 24 V power for PT2001-A1 or
PT2002-A1.
Alternative power supply for PT2001-A1, PT2002-A1, and media converter
PN2007-A1 and repeater PNA2007-A1 via the PP2004-A1 power supply, approved
in accordance with EN 54-4.
