3IF792.9 Interface Module (B&R)
 Product Introduction

3IF792.9 is an aPCI multi-interface communication module from the B&R 2005 system platform. It integrates 2 X2X Link master stations and 1 RS232, specifically designed for the aPCI slot of B&R controllers. It can manage two sets of distributed I/O or servo drives simultaneously and provides serial port connections for third-party devices, suitable for complex automation systems that require multi-bus isolation networking and serial communication. It is the core module of the compact multi-interface expansion.

Status and Diagnosis

LED Indicator Lights: IF1 has 2 lights (Tx/Rx); IF2 and IF3 each have 2 lights (Tx/Rx), respectively indicating data reception and transmission status

Diagnostic Function: Through LED and Automation Studio, can monitor the communication status of the three interfaces, link quality, station connection, and fault codes, supporting rapid location of communication interruptions, offline stations, etc.

Core Functions Three-interface integration: Dual X2X Link master station + RS232. A single module realizes the integration of multiple buses and serial ports, simplifying the system architecture.

Dual bus isolation networking: The two X2X Link lines are isolated from each other, allowing independent control of I/O or drivers for different areas, and supporting redundancy and partition control.

High-speed real-time communication: X2X Link has low latency and high synchronization, meeting the motion control requirements such as multi-axis linkage and high-speed I/O acquisition.

RS232 flexible expansion: RS232 is compatible with third-party serial port devices, enhancing system compatibility and scalability.

Industrial-grade reliability: Wide temperature operation, multi-channel electrical isolation, built-in terminal resistors, suitable for harsh environments such as machine tools and workshops.

Seamless integration of B&R system: Fully compatible with 2005 series CPUs, X20/X67 I/O, and servo drives, unified configuration and programming in Automation Studio.

Application fields
