Description
Overview
The SPNPM22 Network Processing Module from ABB Symphony Plus serves as a high-speed gateway between Cnet and Control way. It integrates a Harmony Control Unit (HCU) database and manages communication with the SPNIS21 module via a dedicated I/O expander bus. This single-slot module features robust microprocessor-based circuitry and dual card edge connectors for power and signal interfacing.
