RS485 to fiber optic converters, DL485/DL485-4W

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 potentialfree contact. If the “traffic light” turns red there is a serious error. Optical linking allows safe data transfer and is suitable for MODBUS, MODNET-1/SFB, BIT-BUS, SAIA-S-BUS and several manufacturer-specific systems.
