Product Description
Product Overview
The Yokogawa ADV551-32DO is a Digital Output Module designed for use in Yokogawa’s CENTUM Distributed Control Systems (DCS) or ProSafe-RS Safety Instrumented Systems (SIS). This module features 32 output channels to transmit 24 V DC transistor contact signals to field devices such as actuators, valves, or relays, providing isolated digital output capabilities. It is typically installed in ESB Bus Node Units or Field Control Units and supports dual-redundant configurations, making it suitable for industrial applications in oil & gas, chemical processing, and power generation where reliable control signaling is essential.
