Yokogawa SNT411-13 CENTUM VP / ProSafe-RS Optical Master

Yokogawa SNT411-13 CENTUM VP / ProSafe-RS Optical MasterProduct Overview The Yokogawa SNT411 13 operates as a high performance Optical ESB Bus Repeater Master Module for CENTUM VP and ProSafe RS Distributed Control Systems. This module converts electrical ESB bus signals into high integrity optical data, facilitating long distance communication between Safety Control Units and remote N IO or Safety Node Units. By pairing the SNT411 13 with an SNT511 slave unit, engineers extend the reach of the system

The AC31 controller and the associated power supply must be de-energized before removing or installing the module to avoid damage to the backplane pins and communication interface circuits
