Yokogawa ANT401-5F ESB Optical Bus Repeater Unit

Feature & Principle

This optical repeater converts electrical ESB bus signal into optical signal for long-distance transmission via optical fiber, and restores to electrical signal at the receiving end. It isolates electrical interference, extends ESB communication distance, realizes interconnection between DCS control nodes, and guarantees stable real-time data transmission of the CENTUM VP system.
