Introduction to ALSTOM N895600 Series Controller

These three models belong to the ECPU/processor module series in the ALSTOM control system, with the core function of executing control logic, managing I/O data processing, coordinating system communication, and serving as the “main control brain” of the entire control architecture.

They are usually installed on ALSTOM dedicated backboards, forming a complete control unit together with I/O modules, communication modules, and terminal modules.

Functions and positioning of each model
1. N895600512D – Control Processing Unit (CPU) module

Mainly responsible for system logic operations and task scheduling

Run control programs and manage I/O data within the rack

Having high processing speed and good stability

Often used as a core CPU, it can replace old versions of control processing cards

Internally equipped with self checking function and fault diagnosis capability

Typical uses: main control logic execution, equipment status monitoring, data collection and processing, system task management.

2. N895600051C – Control Interface/Logic Allocation Module

Mostly used to work in conjunction with the CPU and provide interface support for the system

Responsible for some underlying communication, signal distribution, or functional expansion (depending on system configuration)

Connect the CPU to the I/O channels in the backplane to make the controller work more stably

It is also commonly used to replace old versions of system interface cards

Typical uses: Backplane communication management, signal routing, system function expansion, auxiliary control logic unit.
