A DCS Q Co., Ltd. - PLC and DCS Industrial Control Equipment Wholesale
Introduction
The Yokogawa AAM11B is a versatile analog input module designed for industrial control systems, delivering precise current or voltage signal acquisition for process automation and monitoring. Whether you’re reading 4–20 mA transmitter outputs or 0–10 V signals from field sensors, this module converts those analog inputs into stable digital data for the controller. Built to integrate into Yokogawa DCS racks (e.g. CENTUM systems), the AAM11B offers flexibility, accuracy and robust isolation — ideal for chemical plants, water treatment systems, energy monitoring, and other industrial environments requiring dependable analog measurement.
