DELTA OVH-8D/SC priemyselný 8-kanálový prevodník RS-485/422 na singlemode optické vlákno, SC duplex, 20 km, na lištu

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.
