DI840 3BSE020836R1 logic independent dual bus electrical interface: This module has a logic independent dual bus electrical interface, which can realize the backup of the electrical interface or a single device to access the dual redundant bus system.
Fiber connection: In a point-to-point network configuration, it supports connecting two Profibus DP bus segments via fiber. At the same time, it also supports the realization of multi-segment Profibus DP bus connection on the fiber bus of the double optical port chain network.
Redundancy function: DI840 3BSE020836R1 uses dual optical ports to achieve redundancy in the dual fiber ring network. When an optical fiber fails, the system can rebuild the network link in a short time (such as 10ms) to ensure the normal communication of the system and realize the self-healing protection function for signal transmission.
Fast configuration: DI840 3BSE020836R1 adopts the proprietary ring network protocol developed by the company, such as Ci-ring, which does not need to set the root node, and can quickly complete the ring formation and ring unring function of the network. In addition, it may have a plug-and-play feature that eliminates the need for complex configuration, simplifying the installation and debugging process for users.
Power supply and protection: DI840 3BSE020836R1 This module has dual power supply redundancy input, such as DC(9-36)V, typical DC24V, power consumption is less than 4W, and has DC1500V voltage isolation and reverse protection function.
