Product Overview

• Part No: N897163510Q, N897163050Q MODEM, N897163100U
• Brand: ALSTOM

• Category: MODEM Communication Modulation & Demodulation ModuleN897163510Q, N897163050Q MODEM and N897163100U belong to ALSTOM legacy N897163 series industrial modem communication Eurocard module family. Different suffix codes represent iterative hardware revisions, which are interchangeable within matching turbine control rack configurations. This module completes digital-analogue signal conversion, realizes long-distance serial data transmission between turbine control rack and remote monitoring station. It receives process parameters, alarm information and operating commands from main controller via backplane bus, performs signal modulation/demodulation, and establishes stable remote communication links. Equipped with built-in signal filtering, surge suppression and isolation circuits, it maintains reliable communication under strong electromagnetic interference in power plant environments. It is an obsolete original maintenance spare widely used for overhaul of thermal power and combined-cycle power plant turbine governing control systems.
