Introduction to ABB CI627A 3BSE017457R1
The ABB CI627A (order number: 3BSE017457R1) is a high-performance multi-protocol communication interface module, renowned as the “interconnection bridge” for ABB AC 800M and 800xA distributed control systems (DCS). As a flagship product in ABB’s S800 communication module series, it integrates diverse industrial protocol conversion capabilities and high-speed data processing functions, specializing in realizing seamless data exchange between upper-level controllers and on-site devices such as sensors, actuators, frequency converters, and remote I/O stations. This module supports multiple mainstream protocols including DeviceNet, Modbus RTU/TCP, EtherNet/IP, and PROFINET, making it widely applicable in discrete manufacturing (automobile welding lines, packaging machinery), process industries (petrochemical, food and beverage), and logistics automation (conveyor systems, intelligent warehouses). Its robust industrial-grade design features 500V AC galvanic isolation between ports and backplanes, effectively resisting electromagnetic interference in complex industrial environments, while the compact DIN rail mounting structure saves cabinet space.
