Application
The remote bus connection subrack S5 connects rack-mounted
systems, especially SIMATIC S5-155U programmable control-
lers, to a redundant or non--redundant remote bus. Electrical
isolation between the local and remote buses is achieved at the
same time.
Non--redundant or redundant DC 24 V or AC 230 V power sup-
plyispossible.
Note: The remote bus connection subrack is not used in the
basic cabinets of the AS 235 and AS 235 H automation systems
and in the OS 265-3 operation and monitoring system (rack ver-
sion) for DC 24 V.
Design
Single-tier 19-inch subrack with 2 slots for bus converter units
UI, optionally with power supply module(s).
The power supply in the case of DV 24 V is from the cabinet
supply of the programmable controller, in the case of AC 230 V
via the power supply module C79451-A3276-A1 (redundant as
option).
