ABB SPDSI13 Digital Input Slave Module

Description

The ABB SPDSI13 Digital Input Slave Module is a high-performance component belonging to the ABB Symphony Plus series (formerly Bailey Infi 90 system), designed for industrial automation applications. As a digital input slave module, its core function is to receive and convert digital signals from field sensors or switching devices, then transmit the processed signals to upper-level control systems like PLC or DCS for further analysis. It supports a wide range of input signal types, including 24V DC, 48V DC, 125V DC, and 120V AC, making it adaptable to diverse field device configurations. Equipped with 16 independent input channels, it can simultaneously handle multiple digital signals, meeting the demands of complex industrial scenarios. The module offers flexible input compatibility, supporting both sink-type (NPN) and source-type (PNP) inputs to match different on-site device signal types. With high signal conversion accuracy and fast response time, it ensures control systems obtain real-time field status data reliably. Renowned for its high reliability, stability, and precision, the ABB SPDSI13 is ideal for industrial environments requiring accurate digital signal processing and seamless integration with automated control architectures.
