ABB CI534V02 3BSE010700R1 Modbus Communication Interface Module

ABB CI534V02 with part number 3BSE010700R1 is a Modbus communication interface module for ABB AC800M DCS system. It acts as a protocol gateway between the AC800M controller and third-party Modbus field devices, supporting Modbus RTU and ASCII protocols over RS485 serial bus to realize bidirectional data exchange.

This module has dual independent RS485 channels for connecting multiple Modbus slaves such as inverters, flow meters and power monitors. It supports galvanic isolation and built-in communication diagnostics. Widely used as spare replacement parts for factory automation, power and chemical plant DCS cabinet maintenance and system integration projects.
