Yokogawa SAI143-S53 S1/A4S10 16-Bit Analog Safety Card

Product Description

Safety-Critical Analog Signal Acquisition

The Yokogawa SAI143-S53/A4S10 is a high-integrity Analog Input Module designed specifically for the ProSafe-RS Safety Instrumented System (SIS). As a vital component of the Field Control Station (FCS), this module provides 16 channels of isolated analog inputs, facilitating the monitoring of critical process variables such as pressure, temperature, and level. The SAI143-S53 is engineered to meet stringent SIL3 safety requirements, ensuring reliable data acquisition for emergency shutdown (ESD) and fire and gas (F&G) applications.

Enhanced Reliability with A4S10 Terminal Interface

This specific configuration features the SAI143-S53 module bundled with the A4S10 terminal block assembly. The A4S10 provides a robust physical interface for field wiring, supporting high-density industrial cabling with secure pressure-clamp or screw connections. The module supports dual-redundancy, allowing two units to operate in parallel to ensure continuous process visibility. With 16-bit A/D resolution and galvanic isolation of 1500 V AC, the SAI143-S53/A4S10 maintains signal precision even in environments with significant electromagnetic interference.
