Product Overview

The SPDSI13 is a high-density Digital Input (DI) module designed for the ABB Symphony Plus (S+ HR) Harmony Rack architecture. It serves as a vital interface between the field environment and the control system, accurately capturing discrete signals from equipment such as limit switches, proximity sensors, push buttons, and motor starter auxiliary contacts. By converting these physical binary states into digital data for the Symphony Plus controller, the SPDSI13 enables real-time monitoring and logic execution. Built for industrial resilience, the module utilizes optical and electrical isolation to prevent field-side electrical noise from compromising the integrity of the Harmony Rack backplane.
