DL485-PB / DL485-PBR – Interface

The systems DL485-PB connect Profibus-field bus networks by fiber optics. With the help of this innovative system, optical bus, star, tree, and mixed structures are possible.

The special multifunctional fiber-optic system DL485-PBR also allows the construction of optical ring structures. The system of this series is especially suitable for applications with strict safety-related requirements for instance: process industry, tunnel ventilation systems, and railway technology.

LEDs and potential-free contacts of a fault detector relay are able to signal defective states.

FiberView works similarly to a traffic light. If the “traffic light” is green, everything is fine. If the yellow LED lights, the budget is still tolerable, but already below a certain system reserve. Additionally to the LED, this pre-warning level is also signaled by a potential-free contact. If the “traffic light” turns red there is a serious error.
