ABB SPDSO14 Symphony Digital Output Module

ABB SPDSO14 Symphony Digital Output Module is a 16-channel digital output module that serves as a Digital Output Slave in ABB Ability Symphony Plus S+ HR I/O (Harmony Rack) systems. It features 16 open-collector outputs (16 CH Open Collector) that provide sinking-type switching to control external loads, and is documented by ABB as the 16-channel digital output option for S+ HR I/O in Symphony Plus catalogs and hardware selectors. The SPDSO14 integrates with the Symphony Plus controller ecosystem to drive field devices such as relays, contactors, and solenoids from a Harmony Rack, enabling scalable, reliable digital output expansion across automation lines. This module’s 16-channel consolidation supports efficient I/O expansion within manufacturing, packaging, and process-control applications, while maintaining full compatibility with ABB's configuration and diagnostics tools for the Symphony Plus platform.
