Product Description

The ADV561-P50 S2 (ADV561) is a high-density digital output module designed for the Yokogawa FIO system, commonly deployed within CENTUM VP Distributed Control System (DCS) architectures. It provides 64 discrete current-sink output channels, enabling centralized control of large numbers of 24 V DC field devices such as solenoids, interposing relays, and status indicators.

As a Style S2 hardware revision, this module represents a refined generation with improved internal layout and thermal characteristics, supporting stable long-term operation in industrial environments.
The P50 configuration includes an integrated pushbutton input for local hardware testing and diagnostics, while the “5” suffix indicates operation without per-channel LED status display. This variant is intended for general-purpose (non-explosion-protected) installations where high-speed switching and maximum channel density are required to conserve cabinet space.

Technical Specifications

Application Scenarios

The ADV561-P50 S2 is well suited for high-density discrete output control in centralized cabinets, including:

• Water and wastewater treatment plants

• Food and beverage processing facilities

• Manufacturing and assembly lines

• General-purpose process automation systems

Its 64-channel density reduces I/O module count and rack space while maintaining fast response times for low-power 24 V DC actuators.

Technical FAQ

Can the ADV561-P50 S2 be hot-swapped in a live system?
Yes. When installed in a redundant Yokogawa I/O nest, the module supports online replacement, allowing maintenance without interrupting the control process.

How does Style S2 differ from earlier hardware styles?
Style S2 maintains the same electrical functionality and specifications as earlier versions but incorporates internal component and layout improvements for enhanced manufacturing reliability, thermal performance, and long-term service life.
