Industrial Hardened EIA 422/485 Serial
Fiber Link/Repeaters
Dymec model 5845 and 5846 Serial Fiber Links are
hardened media converters and link/repeaters for
EIA 422 and 485 data connections. The 5845/5846 Links
provide reliable serial data connectivity over fiber
optic facilities in harsh environments where immunity
and signal isolation are critical. Optical connectivity
provides for flexible, extended-distance connectivity,
increases operational safety, reduces equipment outages
due to electrical surges and improves signal quality and
network performance.
5845/5846 Links support signal rates from DC to 2 Mbps
and operate either full- or half-duplex over single- or
multi-mode fiber. Links are easily field-configurable for
point-to-point, master/slave, loop, bus or star topologies.
Logic Inversion enables interoperability with Model
5843/5844 links to mix RS232 and EIA 422/485 end devices in
the same local networking configurations. The 5845/5846 also
connect optically with the DynaStar Network Integration
System and Optical Star products to cost-effectively create
highly scaleable data networks with minimum electrical
signal exposure.
Dymec Links are substation-hardened to C37.90 and IEEE
P1316 specifications. They operate in an extended
temperature range and take DC power directly from station
battery. Dymec Links media converters are Class 1, Div 2
certified for use in hazardous locations in the US and
Canada. The Class 1, Div 2 certification mark allows use of Dymec Links in
ignitable environments requiring spark-free operation. This
is a requirement for many customers, particularly those in
petroleum and petrochemical applications, where hazardous
ignitable environments abound. Flexible mounting options,
diagnostic LEDs and integrated optical and electrical signal
test features make turning up a Link network simple.
