Introduction to ALSTOM N897066510E/N897066010M/AOVD/N897066000A Power System Modules

These are several Analog Output (AOVD series) functional modules belonging to the ALSTOM power and process control platform, commonly used in large-scale power plants, substation automation systems, and high reliability industrial control devices. They are mainly responsible for converting digital instructions within the control system into analog signals that can be used by field devices, achieving precise adjustment and execution control.

Core functional features
1. High precision analog output

The output form is usually industrial standard signals such as 4-20 mA, 0-20 mA, or 0-10 V.

High stability, suitable for precision execution equipment such as valves, regulators, frequency converters, excitation systems, etc.

2. Multi channel structure

The module provides different numbers of independent analog output channels based on the model.

There are isolation measures between channels to reduce interference, improve controllability and safety of operations.

3. Strengthen anti-interference ability

Specially designed for strong electromagnetic interference environments such as power plants, substations, and unit control.

Excellent surge resistance, voltage spikes, and electromagnetic noise performance ensure long-term reliable operation.

4. Seamless integration with ALSTOM control system

Compatible with ALSTOM related main station CPU, control rack, and I/O communication architecture.

Can participate in key functions such as closed-loop regulation, power control, excitation regulation, and load distribution.

5. Typical application areas

Power plant boiler/turbine control system

Power grid automation and regulation circuit

Control of primary and secondary equipment in power transmission and distribution stations

Accurate execution output of industrial processes (pressure, flow, temperature regulation)
