The ACREL Smart Motor Protection and Control Relay is designed to provide a combination of motor protection, measurement, control and communication within low-voltage motor circuits.

The controller supports motor operating voltages of 220 V, 380 V and 660 V at 50 Hz or 60 Hz. Current measurement can be configured across several rated current ranges, including versions using an external current transformer for applications from 0.1 A to 5000 A.

The ACREL Smart Motor Protection and Control Relay also provides programmable digital inputs and outputs, allowing its control functions to be adapted to different motor control arrangements. Communication options include Modbus RTU and Profibus-DP, making it suitable for connection to supervisory or automation systems.

How it works

  • The controller monitors motor electrical and protection-related parameters such as voltage, current, power, power factor, frequency and leakage.
  • It provides multiple motor protection functions to help detect and respond to abnormal operating conditions.
  • Programmable digital inputs and outputs allow the controller to interact with motor control circuits.
  • A start control function provides motor starting control through the controller.
  • Measurement and operating information can be communicated through Modbus RTU or Profibus-DP.
  • Up to 20 fault records can be retained for reviewing previous motor protection events.

Why choose this product?

  • Integrated motor protection and control - combines several motor management functions in one device.
  • Flexible control logic - programmable logic supports different control requirements.
  • Industrial communications - Modbus RTU and Profibus-DP allow connection with compatible automation and monitoring systems.
  • Configurable I/O - nine programmable digital inputs and five programmable digital outputs provide flexibility for control applications.
  • Wide current coverage - supported current configurations extend from low-current motor applications through to high-current systems using external current transformers.

Benefits

  • Helps centralise motor protection and monitoring functions.
  • Provides access to motor operating measurements for control and monitoring systems.
  • Allows protection and control functions to be configured for different applications.
  • Fault records can assist with reviewing motor protection events and troubleshooting.
  • A 4-20 mA analogue output is available for applications requiring an analogue measurement signal.
