Redundant Processor Module PM645B ABB for Continuous Operation MC-TAIH22 proportional analog current or voltageOverview The ABB PM645B is a central processing unit (CPU) module used in Advant Controller 160 Version 2. 2 systems. It is engineered for redundant processor configurations, allowing two PM645B modules to operate in parallelone as the primary and the other as a hot standby. This architecture ensures zero downtime failover, which is essential for mission critical applications in power generation, chemical processing, and transportation control
