ABB 3BSE012211R1 BOARD DSBC-174 3BSC980004R615 COMMUNICATION MODULE

ABB DSBC-174（Order PN:3BSE012211R1，PCB PN:3BSC980004R615）is rugged bus communication interface module for ABB Advant Master legacy distributed automation rack system. The DSBC-174 communication module acts as data exchange gateway between rack master CPU and slave I/O cards via internal Advant fieldbus. This DSBC-174 communication module transmits analog measurement data, discrete status signals and control command across rack backplane bus. The DSBC-174 communication module adopts vibration-resistant construction, conformal coated PCB option for marine and industrial control cabinet environments.

This module delivers rack backplane bus communication & bidirectional process data transmission logic control. The rack backplane bus communication & bidirectional process data transmission logic control receives process and alarm data from field I/O modules. The rack backplane bus communication & bidirectional process data transmission logic control forwards control commands from main CPU to local I/O units. The rack backplane bus communication & bidirectional process data transmission logic control monitors bus communication quality and detects module signal failure. The rack backplane bus communication & bidirectional process data transmission logic control prevents system false alarms caused by bus communication disturbance. The rack backplane bus communication & bidirectional process data transmission logic control supports built-in hardware self-diagnosis for maintenance troubleshooting.

This ABB spare is an essential legacy automation rack bus communication spare for Advant control cabinet overhaul. The legacy automation rack bus communication spare can replace faulty DSBC-174 3BSE012211R1 module assemblies directly. The legacy automation rack bus communication spare meets IEC automation component specifications. The legacy automation rack bus communication spare is widely fitted on large industrial plants, platform and marine engine room automation racks.

ABB DSBC-174 communication module is classic Advant rack bus interface unit. It manages bidirectional data exchange between main controller and distributed I/O modules, performing reliably under vibration and humid industrial & marine machinery room environments.
