ABB PFSK151 DSP Signal Processing Module – AC800M Series
When a DSP signal processing module fails in a live DCS environment, the consequences are immediate and severe: analog and digital I/O signals lose synchronization, control loops go open, and operators are left flying blind. In process-critical industries — oil & gas, power generation, pulp & paper — even minutes of uncontrolled operation can trigger emergency shutdowns, product loss, or safety incidents. The ABB PFSK151 (3BSE018876R1) is the dedicated DSP signal processing backbone of the AC800M controller family, and there is no generic substitute.
Within the AC800M ecosystem, the PFSK151 occupies a pivotal role: it handles real-time digital signal processing tasks that the main CPU offloads, enabling deterministic scan times and high-channel-density I/O management. Globally, the AC800M platform is deployed across thousands of refineries, power plants, and chemical facilities, making the PFSK151 one of the most sought-after spare and replacement modules in the ABB DCS aftermarket.
