Yokogawa ALD112-S00 S1 DeviceNet Communication Module CENTUM DCS

Product Description

The ALD112-S00 Style S1 (ALD112) is a dedicated DeviceNet communication interface module engineered for Yokogawa’s CENTUM VP and CENTUM CS 3000 Distributed Control Systems (DCS). Functioning as a high-performance DeviceNet master, this module facilitates the seamless integration of third-party fieldbus devices into the Yokogawa control environment. It allows Field Control Units (FCU) to exchange cyclic and acyclic data with DeviceNet-compatible sensors, motor starters, variable frequency drives (VFDs), and pneumatic actuators.

The ALD112-S00 Style S1 (ALD112) is designed for mission-critical industrial automation, providing a stable bridge between the DCS backplane and the DeviceNet physical layer. It supports a wide range of baud rates and is optimized for deterministic data throughput. By offloading communication processing from the main controller CPU, the module ensures high system responsiveness and simplifies the management of complex multi-vendor instrumentation networks.
