Blue Jay - Model PR 260 -digital motor protection relay
PR 260 is modular design motor managerment device, accommodate more I/O modules. Flexible arrangement of motor control modes and state sensing. monitors voltage, current, and temperature to provide a comprehensive package of 22 protective functions. with integrated protection, motor control, metering, and data-logging functions. This system is typically used to provide protection for three-phase low- and mediumvoltage, mediumto high-horsepower induction motors.The PR260 motor protection controller adopts a modular design with a small footprint, allowing for a spliced combination of functional modules and offering a flexible structure, suitable for standard rail installation with an external high current transformer and adaptable to various applications. It consists of the following components:
Main control module (mandatory): This is the core component responsible for overall control and protection.
Measurement module (mandatory): This module measures key parameters such as current, voltage, and power. It also includes connecting cables for integration with the motor. With the built-in residual current transformer in the measurement module, the PR260 electric motor protective relay can be easily installed without additional wiring.
Switching module (optional): This switching module provides additional switching capabilities for specific applications.
Display module (optional): This display module (HMI) utilizes a dot matrix LCD and highlighted indicator lights to clearly show operating status and data. offers a visual interface for monitoring the motor’s status and parameters. With the connecting cables, it can easily connect to the main control module.
