YOKOGAWA

The YOKOGAWA AAI135-H is the HART-enabled variant of the AAI135 analog input module for the CENTUM VP / CS 3000 distributed control system. The "-H" suffix specifically indicates support for HART digital communication, allowing configuration and diagnostics of smart field transmitters without interrupting the 4–20 mA analog signal.

The YOKOGAWA AAI135-S is an 8-channel isolated analog input module for the CENTUM VP / CS 3000 distributed control system. It accepts 4–20 mA DC signals from field transmitters.

The YOKOGAWA AAR181 is a 12-channel isolated RTD (Resistance Temperature Detector) input module for the CENTUM CS 3000 / VP distributed control system. It is designed specifically for direct temperature measurement using RTD sensors, converting resistance signals into digital process values.

The YOKOGAWA AAT141 is a 16-channel isolated thermocouple (TC) / millivolt (mV) input module for the CENTUM CS 3000 / VP distributed control system. It is specifically designed for temperature measurement and low-level voltage signal acquisition, not for standard 4–20 mA current signals.

The YOKOGAWA AAV144 is a 16-channel isolated analog input module for the CENTUM VP / CS 3000 distributed control system (FIO). It accepts voltage signals and is designed for high-density process signal acquisition.

The YOKOGAWA AAI543 is a 16-channel isolated analog output module for the CENTUM VP / CS 3000 distributed control system. It converts control commands into 4–20 mA DC signals to drive field devices such as valves, positioners, and converters.

The YOKOGAWA AAI143 is a 16-channel isolated analog input module for the CENTUM VP / CS 3000 distributed control system (FIO). It accepts 4–20 mA DC signals and supports HART communication on the "-H" suffix variants.

The YOKOGAWA AAB841 is a combined analog input/output module for the CENTUM VP / CS 3000 distributed control system. It provides 8 voltage inputs (1–5 V DC) and 8 current outputs (4–20 mA DC) in a single, non-isolated footprint.

The YOKOGAWA AAI841-H is the HART-enabled variant of the AAI841 analog I/O module for the CENTUM VP / CS 3000 distributed control system. The "-H" suffix specifically denotes support for HART digital communication, distinguishing it from the standard "-S" type.

The YOKOGAWA AAI841-S is a standard-type analog input/output module for the CENTUM VP / CS 3000 distributed control system. It provides 8 analog input channels and 8 analog output channels (4–20 mA), with a non-isolated channel architecture.

The YOKOGAWA ADV869 is a digital input/output module for the CENTUM VP system, designated as an ST5-compatible module with 32 inputs and 32 outputs.

The YOKOGAWA ADV159 is a 32-channel digital input module designed for ST3/PBS-compatible control systems, featuring per-channel isolation and a pushbutton input function for edge counting.
