1. General Introduction
SNB10D Dual-Redundant ESB Bus Node Unit has an interface function that communicates the analog I/O signals and contact I/O signals of a field with a Safety Control Unit (SCU) via an ESB bus, as well as a function that supplies power to the I/O Modules. This node units are connected to SCU via an ESB bus.
