ALSTOM E32OUT series N895609510K, N895609010R, N895609100P Eurocard high-density digital output board, spare hardware for legacy steam turbine governing racks with TRENO bus architecture.

Product Overview

• Part No: N895609510K, N895609010R, E32OUT, N895609100P
• Brand: ALSTOM

• Category: E32OUT 32-Channel Digital Output ModuleN895609510K, N895609010R and N895609100P belong to ALSTOM E32OUT high-density digital output module family for turbine control systems. Different suffix letters represent successive hardware revisions, functionally interchangeable within matched TRENO bus control racks.This Eurocard plug-in module provides 32-channel digital logic outputs. It receives command data from ECPU main processor via backplane TRENO bus, converts internal logic signals into field drive signals to control relays, solenoid valves, trip circuits, auxiliary actuators and alarm indicators. Built-in opto-isolation, overcurrent protection and EMI filtering prevent external circuit interference and backfeed damage. It is a discontinued critical maintenance spare widely applied for overhaul of thermal power and combined-cycle power plant steam turbine governing & protection systems.
