B&B 232/422/485 TO FIBER DIN RAIL
The B&B Electronics 232/422/485 to Fiber DIN Rail converter is a rugged, industrial-grade solution designed to bridge legacy serial equipment with modern fiber optic networks. This versatile device lets you mix and match RS-232 devices with RS-422 and RS-485 devices by translating serial signals to a fiber optic link, all mounted conveniently on a standard DIN rail for tight control-room or factory-floor installations. By consolidating conversion and isolation into a single unit, it replaces multiple components, reduces panel real estate, and simplifies maintenance. With Automatic Send Data (ASD) control for RS-485, you can eliminate the need for driver software, speeding up deployment and reducing configuration errors. The result is a robust, long-distance serial connectivity solution that delivers reliable performance in electrically noisy environments, where copper cabling would struggle to maintain signal integrity.
- Flexible serial-to-fiber networking: Seamlessly connect RS-232 devices to RS-422/485 networks over a fiber link, enabling legacy equipment to communicate with modern control systems without replacing existing serial hardware.
- DIN rail mountable for industrial environments: A compact, rugged enclosure is designed to snap onto standard DIN rails, making it easy to deploy in control panels, machine cabinets, and distributed automation environments.
- Automatic Send Data (ASD) control for RS-485: ASD eliminates the need for driver software by automatically managing data enable signaling on RS-485 lines, reducing setup time and the potential for misconfiguration.
- Long-distance, EMI-resistant fiber link: By encoding serial data onto a fiber optic channel, the device delivers superior immunity to electromagnetic interference and allows communication over extended distances compared with copper.
- Streamlined deployment—replaces multiple parts: Designed to replace a separate serial-to-fiber converter and an isolator, this unit simplifies your network topology and reduces spare parts inventory while maintaining critical isolation where required.
