UAC389AE02 HIEE300888R0002 | ABB Control board module

Description

It is a microprocessor-based controller that provides a range of control and alarm functions. It has a large, easy-to-read display that displays current process values, set values, and alarm status. The controller has a number of configurable inputs and outputs that can be used to connect to various sensors and actuators. The UAC389AE02 is designed for a variety of applications, including temperature, pressure, level and flow control. It is particularly suitable for applications that require precise control, such as pharmaceuticals and food processing

argument Set point: The desired process value that the controller will maintain. Proportional, Integral, and differential (PID) tuning parameters: These parameters are used to adjust the controller's response to changes in process conditions. They can be used to optimize controller performance and reduce overharmonic oscillations. Alarm Settings: The UAC389AE02 can be configured to provide a range of alarm functions, including high/low process alarm, deviation alarm and rate of change alarm. Input and output scaling: The input and output of the controller can be scaled to match the range of sensors and actuators used. Control Mode: The UAC389AE02 can operate in a variety of control modes, including on/off, proportional and PID.

Dc classification
The excitation mode of DC motor can be divided into four categories: separate excitation, parallel excitation, series excitation and compound excitation.
Rectification classification
1. Rotary excitation
Rotary excitation also includes DC AC and brushless excitation.
2. Static excitation
Static exciter includes potential source static exciter and composite source static exciter.

Exciting machine
Ac power supply mode according to generator excitation
1. Ac excitation (separate excitation) system
It is powered by an AC exciter coaxial with the generator. The system can be divided into four ways:
1) AC exciter (magnetic field rotation) plus static silicon rectifier (brush).
2) AC exciter (magnetic field rotation) plus static thyristor rectifier (brush).
3) AC exciter (armature rotation) plus silicon rectifier (brushless).
4) AC exciter (armature rotation) plus thyristor rectifier (brushless)..
2. Full static excitation (self-excitation) system
When the excitation transformer is connected to the machine end of the generator or to the plant power bus of the unit generator set, it is called self-excited excitation mode, and the excitation transformer at the machine end and the excitation converter in series of the generator stator are combined to supply power to the generator rotor. There are also four kinds of this combination method:
1) Connect the DC side in parallel
2) DC side in series
3) Parallel AC side
4) AC side in series

The company focuses on DCS, PLC, robot, large servo four systems
