DL-485-ST, MODBUS omvormer voor ring verbindingen over HCS fiber optic.


The fiber optic systems DL485-MBR secure the optical data transfer within MODBUS networks up to a data speed of 115,2 KBit/s. Our special multifunctional fiber optic system allows the construction of optical ring structures.

The system of this series is especially suitable for applications with strict safety-related requirements as 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.
