RS485 4-wire to bus-star singlemode converter, DL485-4W-2x
The DL485-4W-2X is a RS485 4-wire converter for singlemode fiber optic bus, star, tree and mixed connections. For adapter you can make the choice between ST, SC or SC-BIDI. BIDI technology means that you need only one fiber for transmitting and receiving of the data.

The fiber optic systems DL485 connect field bus systems with RS485 interfaces. Optical linking allows safe data transfer and is suitable for MODBUS, MODNET-1/SFB, BIT-BUS, SAIA-S-BUS and several manufacturer-specific systems.
The fiber optic systems DL485-4W connect field bus systems with RS485 four-wire interfaces.
With the help of this innovative system optical bus, star, tree and mixed structures are possible.
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. fiber optic systems DL485 connect field bus systems with RS485 interfaces. Optical linking allows safe data transfer and is suitable for MODBUS, MODNET-1/SFB, BIT-BUS, SAIA-S-BUS and several manufacturer-specific systems.
