Overview

The SNT411 Optical ESB Bus Repeater Master Module serves as an intermediary in the optical transport of the ESB Bus signal. It connects to the Safety Control Unit’s ESB Bus Coupler Module (SEC401, SEC402) or the Safety Node Unit’s ESB Bus Interface Module (SSB401) using an ESB Bus cable. The module is available in two variants: one with a terminator and one without.

Specifications
