Yokogawa SAI143-H03 16-Channel Analog Input Module – CENTUM VP / CS 3000 DCS Series
When a critical analog input module fails on the plant floor, the consequences are immediate: process variables go blind, operators lose visibility into temperatures, pressures, and flows, and safety interlocks may trip the entire production unit. In high-stakes environments — oil & gas, chemical processing, power generation — even minutes of unplanned downtime translate into tens of thousands of dollars in lost production and potential safety incidents. The Yokogawa SAI143-H03 is the precision-engineered solution that keeps your DCS system seeing clearly, every second of every shift.
The SAI143-H03 is a 16-channel analog input module purpose-built for Yokogawa’s CENTUM VP and CS 3000 Distributed Control Systems — two of the most widely deployed DCS platforms in global process industries. Within the SAI143 family, the H03 variant delivers high-density signal acquisition with robust channel isolation and noise immunity, making it the preferred choice for demanding field environments where signal integrity is non-negotiable. Yokogawa DCS platforms command a significant share of the global process automation market, and the SAI143-H03 is a cornerstone I/O module that keeps these systems running at peak performance across refineries, chemical plants, and power stations worldwide.
