ACREL ARD2M Smart Motor Protection Relay with RS485 is a multifunction three-phase motor protection relay for low-voltage motor circuits. It combines motor protection, electrical measurement, programmable control and communication functions, with current transformer options covering motor currents from small motor applications through to 800 A. RS485 Modbus RTU and Profibus-DP communication options allow the relay to be incorporated into industrial motor control and monitoring systems.
 
The suffix designation (e.g., -1, -25, -100, -800) generally denotes the rated current frame or matching external current transformer (CT) scale supported by the intelligent controller unit for comprehensive motor management.

Additional Options

The ACREL ARD2M Smart Motor Protection Relay with RS485 is designed for monitoring and protecting low-voltage motor circuits where motor operating conditions need to be measured and protection functions integrated into the control system.

The relay monitors electrical parameters and provides a range of motor protection functions, including overload, phase loss, current unbalance, locked rotor, underload, voltage-related protection and temperature protection when the appropriate sensor configuration is used. Residual current protection is also available as a configured function.

Its programmable inputs and outputs allow the ARD2M to be used with different motor starting and control arrangements. Communication options include RS485 Modbus RTU and Profibus-DP, providing a practical interface for connection to industrial control and monitoring systems.

How it works

  • The ACREL ARD2M Smart Motor Protection Relay with RS485 measures motor electrical parameters through its associated current transformer and voltage connections.
  • The relay evaluates measured conditions against configured protection parameters.
  • When a defined fault or abnormal operating condition is detected, the protection and relay outputs can respond according to the configured settings.
  • Programmable digital inputs and outputs allow the device to interact with motor control circuits.
  • Communication interfaces allow operating information and parameters to be exchanged with a compatible control or monitoring system.

Why choose this product?

  • Combines motor protection, measurement and control in one device.
  • Provides current transformer options for a broad range of motor currents.
  • Can be installed with the transformer integrated or separately.
  • Supports industrial RS485 Modbus RTU and Profibus-DP communication.
  • Programmable inputs and outputs provide flexibility for different control arrangements.
  • Suitable for applications where motor operating information needs to be available to a supervisory or automation system.

Benefits

The ACREL ARD2M Smart Motor Protection Relay with RS485 can reduce the need for separate motor monitoring and protection devices by combining several functions within one controller. Its configurable architecture also makes it suitable for motor control panels where space, wiring and communication requirements vary between installations.

The available measurement and event functions can assist maintenance personnel in identifying motor operating conditions and recorded events, helping with fault investigation and ongoing motor management.
