ABB INSUM MCU1 Motor Control Unit MCU1A01C0-3 Rev A 1SCA022622R3150

·        Motor Control Unit (MCU) is a product range of electronic motor control and protection devices with a fieldbus interface.

·        Typically MCU is located into the motor starter, where it’s main task is protection, control and monitoring of a 3-phase/1-phase AC motor and motor starter equipment.

·        MCU is connected to the other starter equipment via digital and analog I/O and to other MCU and control system(s) via fieldbus interface.

·        MCU1 is a basic low-end motor controller device for motor and starter equipment protection, control and monitoring.

·         MCU2 is a high-end motor controller device based on the MCU1.

·        MCU2 offers more comprehensive set of motor and starter equipment protection, control and monitoring functions.

·        Additionally some process control related functions are included.

·        MCU1 has 12 and MCU2 has 17 digital inputs of the type 10 mA / 24 VDC.

·        Digital input is activated when connected to the corresponding common terminal.
