CAN BUS/DeviceNet/CAN Open Fiber Optic Repeater Datasheet

CAN BUS/DeviceNet/CAN Open Fiber Optic Repeater

【Summarize】
This series is designed for using in optical CAN fieldbus networks, supporting CAN2.0A/B protocol: CAN、DeviceNet、CAN Open、
SDS、
NMEA2000、
SAE J1939、
SAE J2284 standard fieldbus etc.Independent dual bus electric interface and 2 fiber interfaces, with redundancy
dual-bus structure and fiber optic redundancy ring network function, which supply safe and efficient redundant long-distance transmission and
relay functions for redundant dual-network system. Shenzhen Comark Technology Co., Ltd. is a professional manufacture for industrial network
equipment, adopting the latest technology, owned the core intellectual property rights, and pioneered the innovation products in this field.
The device’s unique characteristics in dual-electric business and dual-optic interface can support dual-network redundancy and fiber optic
ring network, point to point, star topology, daisy chain bus, ring network and hybrid network architecture.
Up to over 60km fiber-optic long-distance transmission breaking through the cable systems distance limitations.
The dual-electric channel is logically independent, support 1 to 2 optic/electric interface collocation flexibly according to actually needs
of the project,1 TX plus 1 FX,1 TX plus 2 FX; 2 TX plus 1 FX,2 TX plus 2 FX,all above types is available. Ci-af series is universal products,
compatible with many types of protocol based on CAN 2.0A/B, rate set by the DIP switch, can support 32 kinds of commonly used rate; Ci-df/of
series is special products against DeviceNet, Can Open, only support all the standard rate, rate set(recommend) or auto negotiation mode is
optional.
The fiber optic transmission with 155Mx2 optical rate can well materialize the advantages of CAN bus: reciprocity transmission, bust of
data, bus arbitration etc., while achieving high-speed long-distance transmission, isolation between electrical and ground, reduce interference and
other performance. Industrial-grade design, IP30 protection, wave patterns aluminum strength case, 35mm DIN Rail mounting, DC (12-36) v
wide power input, alarm relay output, dual-power redundancy and isolation protection,etc.

【Feature】
Support logically independent dual-can bus; include CAN2.0A and CAN2.0B, 32 kinds of configurable rate.
DeviceNet、CAN Open bus support manually set all the standard rate or rate adaptive.
1 to 2 channels CAN electric interface and 1 to 2 channels 155M optical interface flexible optional, support optical ring network topology
with redundancy dual-network.
Over 60km optical transmission distance, 155Mb/s, high-speed optical interface better support burst of data and long-distance reliable
transmission.
6 dual-color LED status indicator, fiber optic link and power failure alarm relay output.
Electric interface with 4000V lightning protection, 1.5A overcurrent, 600W surge protection, industrial-class design, EMC testing and
certification.
DC12-36V wide range redundancy dual power, DC1500V power isolation, reverses polarity protection.
IP30 protection, wave patterns aluminum strength case, standard industrial 35mm DIN rail mounting.

【Network Topology】
Network deployment topologies can achieve the following network connection: point to point communication, chain network, star
network, redundant dual-network and fiber optic ring network self-healing protection etc.
This product applied flexibly, can form a variety of fiber-optic network. Logically independent dual-bus electric interface, backup the electric
interface can be achieved or single equipment access to redundancy system; 2 canbus network segments connected by fiber optic can be achieved
when using point to point network; the optical bus with dual-optical port chain network can achieve multi-network segments canbus
connection(up to 200); meanwhile, this product use dual-optical port to achieve dual-fiber ring network redundancy function, fiber failure
somewhere, system will rebuild the network link within 10ms to ensure the normal communication. This series adopt the company’s own R&D
