3BSE018105R1 is a complete processor unit kit for ABB AC800M control platform under System800xA architecture. Compliant with IEC61131‑3 standard, it supports multiple programming languages for complex process control, sequence interlock logic and analog closed‑loop regulation. The kit comes fully assembled with CPU, mounting baseplate, bus terminators and backup battery, which simplifies on‑site installation and spare‑part replacement work.

This CPU supports 1:1 hot‑standby redundancy configuration to realize bumpless switchover when main controller fails, meeting high‑availability requirements for continuous production facilities. Rich communication interfaces connect S800 I/O modules, field‑bus instruments and upper monitoring systems. Built‑in lithium battery protects application programs and real‑time runtime data against unexpected power loss. Rugged hardware with reliable EMC performance ensures long‑term stable operation in harsh plant‑site environments.

Typical applications cover power generation, petrochemical, pulp & paper and large‑scale process manufacturing automation. Back up all application programs before replacement and confirm firmware compatibility. Complete redundancy synchronization after installation. Fully cut off power supply during module maintenance. Suitable for on‑site fault replacement and long‑term spare stocking for running System800xA / AC800M systems.
