The Yokogawa SAI143-S33 is a high-reliability current input module designed for mounting on the safety node unit and safety control unit within the ProSafe-RS safety instrumented system. This module plays a critical role in safety functions by inputting 4 to 20 mA signals from field instruments directly into the Safety Control Station (SCS). It supports dual-redundant configurations to achieve enhanced system availability and fault tolerance. The SAI143-S33 features standard individual channel configuration pins for 2-wire or 4-wire transmitters and provides module isolation for its 16 processing channels.
