ABB SPBRC300 Bridge Controller

Feature & Principle

It is a high-performance bridge main controller of ABB Bailey Symphony Plus (INFI90) DCS series. It adopts 32-bit processor, runs function block control programs, completes PID regulation, sequence control and interlock protection. It supports one-to-one redundant hot backup, seamless switchover without disturbance when the master unit fails. It communicates through Harmony Control Network and Controlway backplane bus, manages up to 64 local I/O modules, and realizes protocol bridging and data interaction between different subsystems. This model is discontinued and mainly used for maintenance of old process control systems.
