Description

Yokogawa ALP121 – Product Description & Technical Specifications
Product Description
The Yokogawa ALP121 is a  Profibus-DP communication module specifically engineered for seamless integration with Yokogawa CENTUM VP DCS and field control systems (FCS). As a core communication component, it functions as a Profibus-DP master device, enabling stable and efficient data exchange between the DCS and various Profibus-DP slave devices such as remote I/O, PLCs, and other industrial field equipment. Compliant with IEC 61158-2 communication standards, it supports flexible data transmission in complex industrial automation scenarios, making it ideal for oil & gas, chemical, power generation, and manufacturing sectors. Engineered with industrial-grade robustness, including galvanic isolation between field and system circuits, it delivers reliable performance in harsh industrial environments. The module is brand-new with original factory sealing, available in stock for fast shipping, and comes with a 12-month warranty.
