Features:
- Installed-base evolution: Provides an HR Series path for existing rack control applications.
- Broad I/O continuity: Can coordinate legacy rack and newer I/O architectures when engineered correctly.
- High-availability options: Redundancy and communication design must be reviewed as a complete subsystem.
BRC300 / SPBRC300 is an ABB Harmony Rack controller used in Symphony and INFI 90 installed-base control architectures.
Its suitability depends on the existing control configuration, rack and I/O processors, communication modules, redundancy hardware, firmware, and Composer project.
Before replacement, capture the complete nameplate and system inventory, back up the validated configuration, and test I/O, communications, sequences, alarms, and failover behavior.
OEM lifecycle status for BRC300 / SPBRC300 should be confirmed for the exact nameplate and revision; Apter Power quotation and stock status remain subject to confirmation.
