Overview
The SCALANCE XC100-4OBR optical bypass relays are ideally
suitable as ballast in Industrial Ethernet networks in linear and
ring topologies with data transfer rates of 100/1 000 Mbit/s. They
are used for uninterruptible connection and disconnection of
SCALANCE X switches.
•
Uninterruptible connection and disconnection of network
nodes by means of integrated optical relays for multi-mode
and single-mode fiber-optic networks
•
Suitable for use in extended networks (e.g. in wind farms,
pipelines, or large chemical plants) thanks to low optical atten-
uation
•
Rugged plastic enclosure in SIMATIC S7-1500 format, with
installation options on standard mounting rail, and SIMATIC
S7-300/S7-1500 mounting rail in different installation positions
•
Rugged, industry-standard node/network connections using
SC FO interfaces
•
Redundant voltage infeed and monitoring of large voltage
range (12 V DC, 24 V DC, 48 V DC)
•
Diagnostics on the device by means of LEDs (bypass
function, configuration, power supply)
•
Fault signaling contact for signaling switching operations
•
Digital input contact for remote function check of the bypass
relay

Benefits
•
Ideal solution for uninterruptible connection and discon-
nection of network nodes, e.g. for maintenance work in MRP
or HRP (high speed redundancy) rings
•
Simple integration into existing Industrial Ethernet line, star
and ring topologies for increasing the availability of the
network
•
Use in harsh industrial environments thanks to wide temper-
ature range and coated PCBs (conformal coating)
•
Integration into extended multi-mode and single-mode
networks thanks to low throughput attenuation of the
integrated optical relay
•
Combination with different network components thanks to
configurable reset delay by means of SET pushbutton on the
device
•
Low installation width (50 mm) enables simple retrofitting in
existing control cabinets
•
High device availability thanks to redundant voltage infeed
and large voltage range (12 V DC, 24 V DC, 48 V DC)
■
Application
The SCALANCE XC100-4OBR optical bypass relays increase
network availability in Industrial Ethernet line, star and ring topol-
ogies, especially in the case of networks in pipelines or wind
farms, for example, that are difficult to access.
