ABB REM620 is a dedicated motor protection and control device. The following are some common parameters:
-
Analog Input Parameters:
- Three-phase current: Programmable at 5/1A.
- Ground current: Programmable at 5/1A.
- Rated frequency: Programmable at 60/50Hz.
- Three-phase and ground voltage: Programmable nominal secondary voltage.
- RTD input: Standard configuration includes twelve RTD inputs, with optional additional RTD inputs.
- mA input: Standard configuration includes four mA inputs.
-
Binary Input and Output Parameters:
- Binary input: Standard configuration includes eight binary inputs.
- Binary output: Standard configuration includes ten binary outputs, plus one Form C self-check alarm output.
In addition, REM620 has many other functional parameters, such as protection function parameters (e.g., thermal overload protection, differential protection, negative sequence current unbalance protection, etc.), control function parameters (e.g., motor start time monitoring, locked-rotor protection, underload monitoring, etc.), and communication parameters (supporting communication protocols such as IEC61850, Modbus, DNP3, etc.). These parameters can be configured and adjusted according to specific application requirements.
