The Yokogawa SAI143-H33 S2 is a 16-channel analog input module designed for CENTUM VP and ProSafe-RS systems. It features full channel isolation, LED diagnostics, and 4-20mA support for high-integrity process control.
The Yokogawa SAI143-H33 S2 serves as a high-density, high-performance analog input interface for the CENTUM VP and ProSafe-RS systems. You can use this module to simultaneously monitor 16 channels of critical process data, such as temperature, pressure, and flow. By delivering a standardized 4-20 mA or 1-5 V DC signal interface, the SAI143-H33 S2 ensures your control system receives accurate, high-fidelity information from field transmitters.
The SAI143-H33 S2 prioritizes system uptime through its robust isolation architecture. It features individual channel-to-channel and channel-to-system isolation, which effectively eliminates ground loops and shields your control logic from field-side electrical noise. This level of protection makes it an ideal choice for Safety Instrumented Systems (SIS), where signal purity is non-negotiable. Furthermore, individual LED diagnostic indicators on the front panel allow your maintenance team to identify channel-specific faults at a glance, reducing mean time to repair (MTTR).
Engineered for longevity, the SAI143-H33 S2 operates reliably in harsh conditions with a wide temperature range of 0 to 60°C. Its compact, rack-mounted design integrates seamlessly into Yokogawa’s standardized I/O cabinet architecture, maximizing space efficiency in high-density installations. Whether you are managing oil and gas refineries, petrochemical plants, or power generation facilities, this module provides the operational durability required for mission-critical process monitoring.
