Product Description
Product Overview
The Yokogawa SAI143-H53/A4D00 is an Analog Input Module designed for precise current signal acquisition in industrial safety systems. This module, part of the Current Input Module series, inputs 4 to 20 mA signals from field devices across 16 isolated channels and supports dual-redundant configurations. Featuring HART communication and a dual-redundant pressure clamp terminal block, it is engineered for robust performance on safety node units and safety control units, as detailed in this General Specification (GS).
