The ACM11 is a high-reliability serial communication module designed for point-to-point data integration within Yokogawa DCS platforms. It is fully compatible with Yokogawa CENTUM VP, Yokogawa CENTUM CS 3000, and Yokogawa ProSafe-RS systems.
The module supports full-duplex asynchronous (start-stop) communication, enabling stable data exchange between Field Control Stations (FCS) and third-party devices such as analyzers, PLCs, and weighing systems. Designed for industrial environments, it offers reliable signal transmission and compact DIN-rail installation.
