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

The DL485 and DL485-4W fiber optic systems serve as vital components for connecting field bus systems with RS485 interfaces, enabling safe and reliable data transfer in industrial applications. These systems support various field bus protocols, including MODBUS, MODNET-1/SFB, BIT-BUS, SAIA-S-BUS, and several manufacturer-specific systems. The use of fiber optics ensures secure communication, making them suitable for environments with electromagnetic interference and demanding industrial conditions.

The DL485-4W system, designed for RS485 four-wire interfaces, introduces innovative capabilities for constructing optical bus, star, tree, and mixed structures, providing adaptability to diverse network topologies. These configurations offer flexibility in designing communication networks tailored to specific industrial requirements.

LED indicators on the DL485 and DL485-4W systems serve as visual cues for monitoring network health. The FiberView system, functioning akin to a traffic light, offers an intuitive representation of the network's status. A green "traffic light" indicates normal operation, a yellow LED signals that the budget is still tolerable but approaching a system reserve threshold, and a red "traffic light" indicates a serious error. Additionally, the pre-warning level is communicated through a potential-free contact, enhancing the system's ability to signal and respond to potential issues.

The DL485 and DL485-4W systems support both multimode and singlemode fiber optic configurations, ensuring adaptability to different communication requirements and distances within industrial settings. This versatility makes them a reliable choice for diverse applications demanding secure and robust RS485 interface connectivity over fiber optics.
