Insert Card Structure
Octopus3000 is a type of 8-port insert card photoelectric isolation
RS-485/422 relay function. It is only need to replace or add insert card
RS-485/422 bus division concentrator, which is available for random
in case of damage and capacity expansion to effectively improve the
configuration of insert card by users, and can also realize the dual
maintenance efficiency.

Photoelectric Isolation of Industrial Level
Normally, RS-485 bus is required to link up different equipments for
ports for the purpose of solving the transmission problems incurred by
coordinated operation in industrial control domain. Due to
distance and differences in ground potential (Octopus3000 can adapt to
environmental differences, ground potential differences among
the RS-485/422 transmission mode, which is provided with 5-digit
equipments may affect the normal communication of equipments.
industrial terminal).
Octopus3000 aims to provide photoelectric isolation above 3KV for all
Protection for Short and Open Circuits
Octopus3 000 is provided with protection for short and open circuits at
one of the port equipments is in failure so as to ensure the normal
all ports. This type of design can ensure the isolation of problem port if
operation of other network sections.
Star-shape Connection
Owing to the unique design, Octopus3000 can provide users with
single structure of original bus into network structure to facilitate the
RS-485/422 star-shape connection mode. This mode can change the
engineering construction significantly.
