Yokogawa AND50-562 RIO Bus Interface Card

Product Overview

The Yokogawa AND50-562 serves as a high-performance interface card engineered for Yokogawa’s Distributed Control Systems (DCS). It facilitates seamless connectivity and robust I/O expansion, specifically targeting dual-redundant RIO bus architectures. We supply this unit as 100% Brand New and Original, providing the hardware foundation necessary to maintain high data integrity and communication uptime in demanding industrial process environments.

Technical Specifications

The AND50-562 combines digital and analog processing capabilities within a compact, rack-ready form factor.

Engineering Advantages

• Hybrid Signal Management: The AND50-562 integrates 16 digital and 8 analog I/O points onto a single interface card. This hybrid configuration allows engineers to consolidate different signal types into one slot, significantly reducing hardware footprint and backplane consumption in crowded marshalling cabinets.

• Redundant Path Security: This card natively supports dual-redundant RIO bus systems. It ensures that control signals reach their destination even if one communication path encounters a fault, preventing unplanned process shutdowns and ensuring continuous data synchronization with the FCS.

• Flexible Mounting Architecture: The design supports both 19-inch rack mounting and DIN rail installation. This versatility allows for rapid integration into standard control room racks or decentralized field enclosures where space and mounting orientation vary.

• Wide Thermal Tolerance: The hardware operates reliably across a temperature range of -20°C to +60°C. This thermal resilience permits deployment in non-climate-controlled environments, protecting the internal CMOS logic against the thermal stresses common in heavy industry.

FAQs

Does the AND50-562 require external power for the I/O points?

The card operates on a standard 24V DC supply. However, depending on your field device requirements (such as 2-wire transmitters), you may need to provide loop power through the interface or an external power distribution block.

How does the card handle communication faults in a redundant setup?

The AND50-562 utilizes the RIO bus protocol to monitor signal health. If the primary bus line fails, the card’s internal logic switches to the secondary redundant path within milliseconds, maintaining the integrity of both analog and digital I/O data without triggering a system alarm.

Can I install this card while the DCS rack is powered?

While many Yokogawa components support hot-swapping, we recommend following the specific safety procedures outlined in your system's hardware manual. Always ensure the RIO bus addresses are correctly set via the onboard DIP switches before inserting the card into a live backplane.

Is this unit a refurbished spare?

Absolutely not. We offer only 100% Brand New original Yokogawa stock. Every AND50-562 arrives in its factory anti-static packaging, complete with the manufacturer’s serial number to guarantee authenticity and a full operational lifecycle.
