SPHSS03 | -40 °C to +70 °C | hot standby synchronization module

Description

roduct Overview

The ABB SPHSS03 is a high-performance, hot standby synchronization module designed for ABB’s AC 800M High Integrity and AC 800M Safety controller families. Its primary function is to ensure flawless and deterministic synchronization between the processors in a redundant (1-out-of-2) controller pair, which is fundamental for achieving high availability and safety integrity levels (SIL). The module manages the precise exchange of data, clock signals, and system states between the primary and standby CPUs, enabling bumpless switchover in the event of a primary CPU failure with zero data loss..
