The ABB Bailey SPDSI13 is a vital Dual Serial Interface Module designed for the Bailey INFI 90® and NETWORK 90® distributed control systems (DCS). Its primary function is to provide two independent, high-performance serial communication channels, enabling seamless data exchange between the control system and a wide array of external intelligent devices.

This module acts as a critical gateway, bridging the powerful INFI-NET loop or the ModuleBus with the world of serial communications. Each of its two channels can be individually configured to support standard protocols such as RS-232, RS-422, and RS-485, making it exceptionally versatile for industrial applications.

Key features and applications of the SPDSI13 include:

Dual-Channel Architecture: Allows simultaneous connection to two different devices, such as Programmable Logic Controllers (PLCs), variable frequency drives (VFDs), barcode scanners, or weigh scales, maximizing integration capabilities and reducing hardware needs.

Protocol Flexibility: Facilitates peer-to-peer communication and protocol conversion, allowing the INFI 90 system to send commands and receive data from virtually any device with a serial port.

Enhanced System Integration: Essential for building a unified automation architecture, it pulls data from peripheral subsystems into the central DCS for comprehensive monitoring and control.

Industrial Reliability: Built to withstand harsh plant floor conditions, ensuring stable and reliable communication for critical processes.

The SPDSI13 is a cornerstone for modernizing and maintaining legacy Bailey systems, proving indispensable in industries like power generation, water treatment, and manufacturing, where integrating older equipment with modern DCS platforms is crucial for operational efficiency and longevity.
