Detailed Product Overview
The Metso D201925 is a high-density digital input (DI) module for the Metso DNA automation platform. It provides 32 isolated channels for acquiring discrete on/off signals from plant equipment.
Each channel is designed to accept standard 24 VDC wet-contact or solid-state sensor signals. The inputs are galvanically isolated from the system bus, protecting the controller from ground loops, voltage transients, and electrical noise commonly encountered in industrial environments.
Channels are organized in banks of eight. Input filtering is software-configurable, allowing the debounce or filter time to be adjusted to match the characteristics of the connected field devices. The module integrates directly into the Metso DNA I/O architecture and is recognized by the system engineering tools for configuration, status monitoring, and diagnostics.
Typical field devices connected to the D201925 include limit switches, proximity sensors, motor run/stop contacts, safety interlocks, and other binary status signals. The high channel density reduces the number of modules required for large discrete I/O counts, helping to optimize cabinet space and wiring.
