Yokogawa SAI533-H33/PRP Safety Analog Output Module

Description

TheYOKOGAWA SAI533-H33/PRPis ahigh-integrity analog output module, specifically designed for use inSafety Instrumented Systems (SIS). This specializedYOKOGAWA componentprovidesreliable control signalstosafety-rated final control elements. The module issafety-certified(typicallyTüV SIL3), ensuring that it meets the highest standards offunctional safetyin process control. TheSAI533designation indicates an8-channel isolated analog output module, with the suffixes-H33and/PRPadding additional clarity regarding the output signal type and redundancy features. -H33signifies the output type and configuration, typically4-20 mA DC. /PRPindicatesPeer-to-Peer Redundancy (PRP), meaning the module is designed for use in aredundant pairto ensuremaximum fault tolerance, making the systemfail-safein the event of hardware failure.
