FBM207B controller

FBM207B is a controller produced by FOXBORO, which features a compact design and a sturdy extruded aluminum appearance for physical protection of circuits. In addition, FBM207B is also a voltage monitor/contact detection input interface module, which can be used as a 16 channel DC voltage monitor or 16 channel contact sensor, and each channel can accept input from a DC voltage source or system.

In terms of network applications, FBM207B has excellent performance. It supports logically independent dual bus electrical interfaces, which can achieve backup of electrical interfaces or single device access to dual redundant bus systems. In addition, the module adopts a point-to-point network design, which can connect two Profibus DP bus segments through fiber optics, or achieve multi segment Profibus DP bus connections on the fiber optic bus of a dual optical port chain network.

At the same time, FBM207B also has dual optical ports to achieve dual fiber ring network redundancy. In the event of a fiber optic failure, the system can reconstruct the network link within 10ms to ensure normal communication and achieve self-healing protection for signal transmission.

The FBM207B module also adopts the proprietary ring network protocol Ci ring developed by the company, which does not require the setting of a root node and can quickly complete the ring formation and ring removal functions of the network. In addition, this module is plug and play and does not require configuration, greatly simplifying the installation and debugging process for users. The transmission distance of FBM207B can reach multi-mode 2Km and single-mode 20Km. The fiber interface types are available in SC, FC, and ST, and SC optical interface is standard.

In summary, FBM207B not only has the characteristics of durability and compact design, but also performs well in network applications and can meet various complex industrial control needs.
