Can Bus Devicenet Canopen Redundant Link Module - China

price: contact company for price

【Summarize】 This product is CAN protocol fieldbus

redundant module; achieve the exchange between single bus and redundant

dual bus, which can connect CAN single port device to redundant bus

network. Real-time monitoring communication status, when working port

receiver detect the fault frame, char error, consecutive busy and

falling short of protocol error or bus consecutive busy for a long time,

will close this port, and then activate the redundant port as working

port. Ci-aa21 series support the fieldbus based on CAN2.0A/B: CANӌ-

9;DeviceNet, CANOoen, SDS, NMEA2000, SAE

J1939, SAE J2284 and so on, rate set by DIP switch (recommend) or

rate adaptive optional, support CAN bus normally used rates. 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. The equipment can be set

after CAN device, change single cable bus to redundant bus, also can

change the redundant cable to non-redundant cable, meanwhile featured

Opto-isolation, reducing interference and other functions. Products
