The SCP461-51 (Model: SCP461-51) is a high-performance Sequence Control Processor (SCP) module specifically engineered for Yokogawa’s CENTUM VP and CS 3000 Distributed Control Systems (DCS). Operating within the SSC60S and SSC60D Field Control Stations, this Style S2 module is optimized for complex sequential logic, batch process execution, and high-speed interlock management.
Built to withstand demanding industrial environments, the SCP461-51 (Part Number: SCP461-51) features enhanced RFI (Radio Frequency Interference) shielding and conforms to ISA Standard G3 for corrosive resistance. It provides deterministic control for mission-critical automation, supporting 1:1 redundancy to ensure zero process interruption. In a dual-redundant configuration, the SCP461-51 (Order Number: SCP461-51) utilizes synchronized data mirroring, allowing a standby module to assume full control instantaneously upon detection of a primary hardware fault.
The SCP461-51 (Model: SCP461-51) is designed for high-availability batch and sequential control with integrated environmental protection.
