Product Description
Product Overview
The Yokogawa AAI841-H50/A4S00 Analog I/O Module is a versatile, non-isolated module designed for Yokogawa’s industrial control systems, such as CENTUM VP, to handle 8 analog inputs and 8 analog outputs supporting up to 8 loops. Featuring 4-20 mA signals for both input and output with HART communication, this module supports dual-redundant configurations for enhanced reliability. With an accuracy of ±16 µA (input) and ±48 µA (output), a 10 ms data update period, and a transmitter power supply ranging from 14.8 V to 26.4 V, it is optimized for precise control in process automation. Equipped with a pressure clamp terminal block and weighing 0.3 kg, it includes no explosion protection and operates efficiently in standard industrial environments.
