The YOKOGAWA ADV551-P50 is a digital output module designed for Yokogawa’s distributed control systems, including CENTUM and other industrial automation platforms. It provides 32 independent output channels delivering 24 V DC transistor contact signals, commonly used for controlling actuators such as solenoid valves, relays, and other discrete output devices. This module is widely applied in process control environments such as power plants, chemical industries, refineries, and manufacturing where reliable, fast, and isolated digital output switching is critical for operational safety and precision control.
The ADV551-P50 features isolated transistor outputs rated for up to 50 mA per channel at 24 V DC, ensuring protection against ground loops and electrical noise that can degrade signal quality in industrial environments. Its compact design supports efficient panel mounting in node units (e.g., ANB10S, ANB11S), optimizing control cabinet space. The module is engineered for fast output response with a pulse width output function and time-proportional output options, enabling flexible control schemes. It supports multiple suffix codes for explosion protection, status display features, and different cable termination options, making it adaptable for various industrial requirements.
Key technical specifications include a maximum output load of 50 mA per channel, with a supply voltage range of 20.4 to 26.4 V DC, and pressure clamp or dedicated cable external connections. The module offers a withstand voltage of 2 kV AC between output signal and system and weighs approximately 0.3 kg, contributing to easy installation and maintenance. It supports dual redundant configurations ensuring high system availability in critical processes.
