ABB PM581 is a controller module produced by ABB.The following is a detailed introduction to it:

1.Basic properties

Brand:ABB

Model:PM581

Series:AC500 series

2.Technical features and functions

Central processing unit(CPU)module:

As a central processing unit module,PM581 has powerful computing and control capabilities.

Logically,it can be divided into control unit,computing unit and storage unit,which are connected by the CPU internal bus.

Fast fault identification and response time:

The PM581 module provides very fast fault identification and response time,which helps to find problems and take measures in time.

Multiple protection functions:

The motor protection relay version of PM581 has multiple protection functions such as overload,underload,stall,short circuit,ground fault,etc.,which fully protects the safety of the motor.

High-precision measurement:

Adopt high-precision sensors and algorithms to accurately measure the current,voltage and other parameters of the motor.

Intelligent diagnosis:

It has a fault self-diagnosis function,which can automatically detect and display the fault type,so that users can quickly locate and handle the fault.

Communication and network capabilities:

Supports multiple communication protocols and interfaces,facilitating data exchange and communication with other devices and systems.

For example,the PM581-ETH version supports Ethernet communication,while the PM581-ARCNET version supports the ARCNET communication protocol.
