ALSTOM 8172-4003 – Digital Output Module | ALSTOM DCS Control Platform
Engineering Background
The ALSTOM 8172-4003 is a digital output module engineered for ALSTOM’s distributed control system (DCS) architecture. Designed to interface directly with field actuators, solenoids, and relay-driven loads, this card delivers deterministic signal switching in high-availability industrial environments. It is a critical I/O component within the ALSTOM 8000-series control platform, widely deployed in power generation, utilities, and process industries.
Product Positioning
Procurement engineers sourcing replacement or expansion I/O cards for ALSTOM DCS installations will find the 8172-4003 to be a direct OEM-compatible solution. Konmask.com supplies this module from verified industrial surplus and authorized distribution channels, with full functional testing prior to shipment.

System Architecture & Signal Flow
Within the ALSTOM 8000-series DCS architecture, the 8172-4003 output module occupies a dedicated I/O slot in the process controller rack. The module receives command signals from the DCS controller backplane via the internal bus, converts them to discrete output signals, and drives field devices (relays, solenoids, motor starters) through its terminal block interface.
Typical Signal Flow: DCS Controller → Backplane Bus → 8172-4003 Output Card → Field Terminal Block → Actuator / Relay / Solenoid
The module supports standard ALSTOM rack wiring conventions and is compatible with existing marshalling cabinet layouts, enabling drop-in replacement without rewiring.
