YOKOGAWA AAI841-H50/A4S00 Analog I/O Module

Description
The YOKOGAWA AAI841-H50/A4S00 is a high-density analog I/O module for the CENTUM VP distributed control system, integrating 8 analog input channels and 8 analog output channels within a single I/O slot. This non-isolated (common-ground) model features the A4S00 pressure clamp terminal block for direct vibration-resistant field wiring . The -H suffix provides integrated HART communication for smart device configuration and diagnostics.

Features

8 analog inputs and 8 analog outputs in one module
HART digital communication superimposed on 4–20 mA signals
Non-isolated common-ground design for cost-effective dense installations
A4S00 pressure clamp terminal block for direct field wiring
10 ms high-speed data refresh rate for dynamic control loops
