DELTA OVH-8D/SC Industrial 8-Channel RS-485/422 to Single-mode Fiber Optic Converter, SC Duplex, 20 km, DIN-Rail

In a sprawling industrial plant, multiple RS-485/422 devices—PLCs, meters, sensors—need to communicate with a central control room hundreds of meters away, where copper cabling is impractical and electromagnetic interference is high. The DELTA OVH-8D/SC solves this by converting eight independent RS-485/422 channels into a single-mode fiber optic link with SC duplex connectors, extending reliable data transmission up to 20 km.
