d-Light Profibus Redundant

Product description

The systems DL-485PBR ensure the optical data transmission in Profibus-field bus networks. A special multifunctional fiber optic system allows creating optical ring structures.

These systems are especially suitable for applications with strict safety-related requirements such as in process industry, tunnel ventilation systems and in railway technology.

The ruggedness to electrical and magnetic interferences, the potential separation of transmitter and receiver as well as ranges up to 40km between two fiber optic systems are important performance features of the transmission with POF, HCS and multimode or singlemode fiber optics. LEDs and potential free contacts of a differential relay signalize defective states.

Apart from ST and SC as optical connection types, E2000 is also available. All systems feature communication with two fibers or a single fiber by BIDI technology with SC connection.

This system is now also available with the fiber optic monitoring technology FiberView.
