Product Overview

• Part No: N897164611M
• Brand: ALSTOM

• Category: Pulse Output Control ModuleN897164611M is an upgraded plug-in pulse output module of ALSTOM industrial control series, derivative model of N897164610L. It generates configurable high-precision pulse signals to govern actuators, valve positioning units and field process equipment. The module supports flexible programming of pulse frequency and pulse quantity, communicates with main controllers via internal system bus, and executes real-time signal conversion and logic output. Equipped with built-in surge filtering and ESD protection circuits, it maintains stable operation under heavy electromagnetic interference. It serves as essential spare component for thermal power plant DCS, turbine control cabinets and heavy industrial automation panels.
