Yokogawa ADM52 ERWEITERUNGSMODUL ID61331 Expansion Module

The Yokogawa ADM52 Expansion Module (ID61331) adds digital output channels to CENTUM DCS racks and other Yokogawa automation cabinets, serving as a dedicated Expansion Module for increasing system output capacity in process-control environments. The module provides transistor contact outputs, with typical ADM52-series characteristics, and supports up to 32 output points depending on the series. Each channel handles up to 30 VDC at 100 mA, enabling control of relays, alarms, and actuators directly from the DCS backplane. It is powered by 5 VDC supplied through the system backplane and mounts in the I/O module nest or expansion rack, with connections made via a terminal block or system interface connector. Functionality covers ON/OFF control, pulse output, and time-proportional output, making it suitable for timing or gated control in batch or continuous processes. Commonly installed in Yokogawa CENTUM DCS configurations and industrial automation cabinets, the ADM52 is used in oil & gas, power generation, and manufacturing environments to expand digital output capacity and maintain reliable control of field devices. Legacy/refurbished units are commonly available, and this part is frequently referenced alongside replacements such as ADM52C and ADV551 to maintain or upgrade digital output modules.
