Application
The remote bus connection subrack S5 connects r ack-mounted
systems,especially SIMATICS5-155U programmable control-
lers, to a redundant or non--redundantremote bus . Electrical
isolation between the local and remote bus es is achieved at the
same time.
Non--redundantor redundant DC 24 V or AC 230 V power sup-
plyispossible.
Note: The remote bus connection subrack is not used in the
basiccabinets of the AS 235and AS 235 H automationsystems
andin the OS 265-3 operation andmonitoring system (rack ver-
sion) for DC 24 V.
Design
Single-tier 19-inch subrack with 2 slots for bus conv erter units
UI, optionally with power supply module(s).
The power supply in the case of DV 24 V is f rom the cabinet
supply of the programmable controller, in the cas e of AC 230 V
via the power supply module C79451-A3276 -A1 (redundant as
option).
