Product Overview
The Yokogawa SNT411 Optical ESB Bus Repeater Master Module extends ESB bus communication by converting electrical signals into optical signals, enabling longer transmission distances up to 50 km. It supports both star and chain type connections and is designed for use in safety control systems (ProSafe-RS). It is typically connected to ESB bus couplers or interfaces and paired with the SNT511 slave module for extended reach.
