YOKOGAWA

The YOKOGAWA AAI141-H is the HART-enabled variant of the AAI141 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 over the 4–20 mA loop.

The YOKOGAWA AAI141-S is a 16-channel analog input module for the CENTUM VP / CS 3000 distributed control system. The "-S" suffix denotes the standard type, which does not include HART digital communication capability.

The YOKOGAWA ANB10D-425/CU2N is a dual-redundant ESB Bus Node Unit for the CENTUM VP / CS 3000 distributed control system. It is functionally identical to the previously discussed ANB10D-425/CU2T, with the only difference being the connector unit option code.

The YOKOGAWA ANB10D-425/CU2T is a dual-redundant ESB Bus Node Unit for the CENTUM VP / CS 3000 distributed control system. It serves as a local node that connects field I/O signals to the Field Control Unit (FCU) via the ESB bus and supplies power to the installed I/O modules.

The YOKOGAWA ADV141 is a 16-channel AC digital input module for the CENTUM CS 3000 / VP distributed control system. It receives high-voltage AC ON/OFF signals from field devices, eliminating the need for external interposing relays.

The YOKOGAWA AAP849 is a pulse input / analog output module for the CENTUM VP distributed control system, compatible with the PAC (Plant Automation Controller) environment. It receives 8-channel pulse train signals and converts them into 4–20 mA analog outputs for integration into standard control loops.

The YOKOGAWA AAP149 is a 16-channel pulse input module for the CENTUM VP / CS 3000 distributed control system, specifically designed to be compatible with the PM1 processor module. It receives pulse train signals from field devices (such as flow meters, tachometers, and encoders) via pulse input signal conditioner cards and counts them for process monitoring and totalization.

The YOKOGAWA AAP135 is an 8-channel isolated pulse input module for the CENTUM VP / CS 3000 distributed control system. It is designed to receive contact ON/OFF, voltage pulse, and current pulse signals from field devices such as flow meters, tachometers, and power transducers.

The YOKOGAWA AAR145 is a 16-channel isolated RTD/POT input module for the CENTUM series distributed control system, designed for temperature measurement using RTD sensors and position feedback via potentiometers.

The YOKOGAWA AAT145 is a thermocouple (TC) / millivolt (mV) input module for the CENTUM VP / CS 3000 distributed control system, featuring 16 isolated channels for temperature and low-level voltage signal acquisition.

The YOKOGAWA AAI835-H is the HART-enabled variant of the AAI835 analog I/O module for the CENTUM CS/VP distributed control system. The "-H" suffix indicates support for HART digital communication, allowing configuration and diagnostics of smart field devices alongside standard 4–20 mA signals.

The YOKOGAWA AAI835-S is a standard-type analog I/O module for the CENTUM CS 3000/VP distributed control system. It provides 4 isolated input channels and 4 isolated output channels (4–20 mA DC) in a single module. The "-S" suffix indicates it is the standard version without HART digital communication capability.
