Product Details
Product Description
The SAI143-H03 from Yokogawa is a high‑performance analog input module designed for integration into the CENTUM VP, CS 3000, and ProSafe‑RS safety instrumented systems. As part of the Field I/O (FIO) subsystem, it provides 16 galvanically isolated channels for acquiring 4–20 mA signals from critical process transmitters.
This module is engineered for environments where uptime and functional safety are essential. The “H03” revision enhances hardware stability and ensures compatibility with modern Vnet/IP architectures. Each channel is isolated to prevent ground loops and protect the backplane from electrical noise. With HART pass‑through capability, the SAI143-H03 supports advanced diagnostics and asset management, making it suitable for petrochemical, oil & gas, and power generation industries.
