Controlnet Fiber Optic Repeater - China

price: contact company for price

Summary: Ci-cf series is a ControlNet protocol fieldbus fiber optic

repeater, support the fieldbus based on ControlNet protocol,

independent dual bus electrical interface and 2 optical interfaces,

supply redundancy dual bus structure and optical fiber redundancy ring

network function, offer redundancy dual networks system the fiber optic

redundancy long distance transmission and relay function with safe and

efficient. Shenzhen Comark Technology Co., Ltd. is a professional

industrial networking equipment supplier; equipments done adopt the

latest technology with their own completed intellectual property

rights, launched the products with the features of industry’s

innovative. This equipment featured of dual electric business and dual

optical ports design, support dual networks redundancy and fiber optic

ring network, simultaneously support point to point, star, daisy chain

bus, ring network and mixed network topology. The fiber optic long

distance transmission grows up to 20km or more, which break through the

distance limitation of cable system. Dual electric business channels

are logically independent, support 1~2 optical/electric interfaces

mixed flexibly, according to the real demand of projects, you can

achieve 1 channel fiber optic interface, 1 channel data interface; 1

channel fiber optic interface, 2 channels data interface; 2 channels

data interface, 1 channel data interface; 2 channels fiber optic

interface, 2 channels data interfaces flexible configuration. Ci-cf

series is the common use goods to achieve the ControlNet standard,

communication rate of 5M. 155M dual optical interface can better

support fiber optic transmission the outstanding advantages of

ControlNet: peering transmission, burst data, bus arbitration,

simultaneously achieve long distance transmission with high speed,

electrical and ground wire isolation, interference reduction and other

performance. Products are industrial design, IP30 Protection Grade,

wave pattern aluminum made enhance case, 35mm DIN Rail installation,

DC(9-36)V widely power input, featured with relay alarm output, dual

power redundancy and isolation protection, etc. Feature: 

Support logically independent dual ControlNet fieldbus.  1~2

channels ControlNet BNC-F electric port and 1~2 channel 155M fiber

optic ports choose flexibly, support redundancy dual fiber optic ring

networking topology.  Longer than 20km, 155Mb/s, high speed

optical interface can better support burst data long distance

transmission reliably.  6 pcs of double colors LED status

illustration light, optical fiber link and power error relay alarm

output.  Electric interface 4000V thunder-proof, 1.5A

overcurrent protection, 600W surge protection. Industrial design, EMC

test certificate.  DC9-36V wide temperature redundancy dual

power, reverse connection protection.  IP30 protection grade,

wave pattern aluminum enhance case, adopt standard industrial 35mm Din

Rail installation. Network topology: Networking topology can achieve

the net link below: point to point communication, chain network, star

network, redundancy dual networks and fiber optic ring network self-

healing protection, etc. The product uses flexibly, can make up many

kinds of fiber optic networks. Logically independent dual bus electric

interface, can achieve electric interface backup or single equipment

access dual redundancy bus system; adopt point to point network can

achieve connecting two segments of ControlNet by fiber optic; adopt

dual optical ports chain-shaped network fiber optic bus achieve multi-network-

segments ControlNet connection; meanwhile, the product adopt dual

optical ports to achieve the function of dual fiber ring network

redundancy, when fiber optic error somewhere, the system will rebuild

the network link within 20ms, to guarantee the normal system

communication, achieve the function of signal transmission self-healing

protection, the system will recovery automatically after the network

troubleshooting; this series products adopt Comark own R&D professional

network protocol Ci-ring, no need any set, no need root segment,

quickly finishing the network function of ring closing and ring

opening, this series products can plug and play, no configuration, to

simplify the user installation procedure at utmost. Specifications:
