ABB REM620C_F Motor Protection and control device is a comprehensive motor protection and control equipment, widely used in the manufacturing and processing industry, especially the need for differential protection of medium and large asynchronous motors. The following is a detailed description of the device:

1. Main functions

Protection: real-time monitoring of the operating state of the motor, including current, voltage, temperature and other parameters, the motor overload, short circuit, undervoltage, lack of equal faults for real-time monitoring and protection.

Control: It has the control functions of motor start and stop, frequency conversion, positive and negative rotation to ensure the safe and stable operation of the motor.

Measurement: Support the measurement of a variety of parameters, such as current, voltage, active power, reactive power, power factor, etc., to provide comprehensive motor operating status information.

Monitoring: With state monitoring and switch circuit monitoring functions, convenient for users to understand the working status of the motor in real time.

2. Technical features

Multi-parameter monitoring: Support real-time monitoring of various parameters in the operation of the motor, with comprehensiveness and accuracy.

Fault protection: Once the motor is found abnormal, the power can be cut off in time to avoid equipment damage and personnel injury.

Remote control: Supports remote monitoring and control functions, improving O&M efficiency.

Self-diagnosis function: With self-diagnosis function, the device can be self-detected and fault diagnosis.

Communication protocol support: IEC61850, DNP3, IEC 60870-5-103, Modbus? and other communication protocols are supported for easy integration with other systems.

3. Configure options

Bus configuration: Single and double bus configurations are available.

Circuit breaker configuration: Each bus configuration has one or two circuit breakers and multiple switching switchgear configurations.

I/O volume: The number of controllable devices and the amount of available I/O depends on the input and output requirements of other applications and can be increased according to the needs of ABB's RIO600 remote I/O devices.

4. Display and operation

Display: Large LCD display with editable single line chart, providing intuitive device status and operation information.

Operation: Accessible and operated locally or through an easy-to-use HMI (Human Machine Interface) based on a Web browser.

5. Reliability

Redundant design: The PRP or HSR protocol provides an optional Ethernet port for redundant Ethernet without delay or a self-healing RSTP communication in the ring network in the event of a communication failure, improving communication reliability.

Product life cycle service: Provide thoughtful product life cycle service to ensure long-term stable operation of equipment.

6. Application field

ABB REM620C_F motor protection measurement and control device is widely used in various industrial production of motor protection and control fields, including manufacturing, petrochemical, power industry, transportation and other fields. In particular, it plays an irreplaceable role in the protection of large equipment and key equipment, providing an important guarantee for the safe and stable operation of equipment.
