AIP121 Style S2 | Yokogawa | CENTUM VP Analog Input Card

Product Description

High-Precision Isolated Signal Acquisition

The Yokogawa AIP121 Style S2 is a specialized Analog Input Processor (AIP) module engineered for the Field Control Station (FCS) subsystem within Yokogawa’s CENTUM VP Distributed Control Systems. This Style S2 revision is a refined 8-channel interface designed for high-integrity signal acquisition where channel density is balanced with electrical isolation. It effectively captures 4–20 mA process signals and DC voltage inputs from critical transmitters, converting them into 16-bit digital values for real-time control logic processing.

Designed for mission-critical reliability, the AIP121 Style S2 is a standard in the petrochemical, power generation, and oil and gas industries. By utilizing 16-bit A/D resolution, the module provides the granular data required for fine-tuned PID control loops and safety monitoring. Its architecture is optimized for the Yokogawa proprietary I/O bus, ensuring deterministic, high-speed communication even in large-scale plant architectures.
