Product Introduction

The ABB CI534V02 3BSE010700R1 is a dual-channel serial communication submodule for ABB Advant OCS AC400 controller system, installed into SC510/SC520 carrier slots. It supports Modbus RTU/ASCII and MasterBus300 protocols with RS485/RS422 selectable interfaces, working as master or slave. 500VDC galvanic isolation protects backplane circuits from field noise. It connects DCS controllers to third-party devices including power meters, protection relays and variable speed drives, widely used in power, chemical and pulp & paper plant control systems.

Content Details

CI534V02 is a plug-in submodule hosted by SC series carrier, not standalone hardware. Two independent serial ports support configurable baud rate from 300bps up to 115.2kbps. It handles bidirectional data exchange between Advant controller and Modbus field instruments. Built-in communication diagnostics monitor link status and report faults to main CPU. Hot swap supported for maintenance without system shutdown. Rugged PCB design with wide operating temperature range, stable under industrial vibration and electromagnetic interference. CI534V02 3BSE010700R1 is used as spare replacement and system retrofit for ABB Advant OCS DCS. Before shipment, each unit undergoes full functional test and thermal aging inspection to eliminate hidden defects and guarantee reliable long-term continuous operation.
