3IF791.9 aPCI interface module (B&R of Beckhoff)
Product Introduction

3IF791.9 is an aPCI single-channel X2X Link master station interface module under the B&R 2005 system. It is specifically designed for the aPCI slot of B&R controllers and provides a native X2X Link high-speed fieldbus master station interface, which is used to connect X20, X67 and other series of distributed I/O nodes, achieving high-density and high-real-time local and remote I/O control. It is compatible with CP360 and other series of CPU controllers, and is the core expansion module for building compact distributed automation systems. Basic Information
