9300 9852 Logic Independent Bus

9300 9852 Features:

* Supports logically independent dual Profibus DP buses with predetermined communication rates in the standard specification.

* Support dip switches to manually set the standard rate or rate adaptive.

* 1~2 way Profibus DP electrical interface and 1~2 way 155M fibre optic interface for flexible selection, support redundant dual-network fibre-optic ring network topology.

* More than 20km optical distance, 155Mb/s, high-speed optical interface to better support burst data transmission over long distances.

* 6 dual-colour LED status indicators, fibre-optic link and power failure relay output alarms.

* Electrical interface 4000V lightning protection, 1.5 A overcurrent, 600W surge protection. Industrial grade design, EMC testing and certification.

* DC9-36V wide redundant dual power supply, DC1500V power isolation, reverse connection protection.

* IP30 protection level, wave pattern aluminium reinforced chassis, using standard industrial 35mm rail mounting.

9300 9852 can achieve the following network connections: point-to-point communication, chain network, star network, redundant dual-network and fibre-optic ring network self-healing protection. 9300 9852 9852 can be used flexibly to form a variety of fibre-optic networks. Logical independent dual-bus electrical interface, can realize the backup of the electrical interface or a single device to access the dual-redundant bus system; point-to-point network can be achieved through the optical fibre to connect the two Profibus DP bus segments; dual-optical port chain network of optical fiber bus to achieve more than one segment of the Profibus DP bus connection (200);
