Product Detail

ALSTOM DIAGNOSTICA series N897093511D, N897093051D, N897093400H Eurocard diagnostic board, spare hardware for legacy steam turbine governing racks with TRENO bus architecture.

Product Overview

Part No: N897093511D, N897093051D, DIAGNOSTICA, N897093400H
Brand: ALSTOM
Category: DIAGNOSTICA Rack System Diagnostic & Monitoring Module

N897093511D, N897093051D and N897093400H belong to ALSTOM DIAGNOSTICA dedicated rack diagnostic module family for TRENO bus turbine control systems. Different suffix letters represent successive hardware revisions and component configurations, functionally compatible within matching control rack setups.

This Eurocard plug-in module continuously monitors the operating status of all internal rack modules, power supply quality, TRENO bus communication health and signal integrity. It collects fault codes, abnormal status and alarm events from ECPU, I/O boards and communication modules, implements fault recording, event logging and local status indication, and transmits diagnostic information to main controller and upper HMI for maintenance troubleshooting. Built-in filtering, surge suppression and ESD protection guarantee stable monitoring under severe electromagnetic interference in power plant turbine governing cubicles. It is a discontinued essential maintenance spare for thermal power and combined-cycle power plant steam turbine control system overhaul.
