Intelligent Modular Unit

Definition

FYI, this map is shared with EIFE, IFE, FDM121, IO Module, MTZ Modbus guide, NT/NW Modbus guide, and NSX Modbus guide.

A modular unit is a mechanical and electrical assembly containing one or more products to perform a function in a switchboard (incoming protection, motor command, and control).

The circuit breaker with its internal communicating components (MicroLogic control unit or MicroLogic trip unit) and external ULP modules (IO module) connected to one communication interface is called an intelligent modular unit (IMU).

An IMU is composed around a circuit breaker from the following ranges:

  • MasterPact MTZ circuit breakers

  • MasterPact NT/NW circuit breakers

  • ComPacT NS 630b–1600 circuit breakers

  • ComPacT NS 1600b–3200 circuit breakers

  • PowerPacT P- and R- frame circuit breakers

  • ComPacT NSX circuit breakers

  • PowerPacT H-,J-, and L- frame circuit breakers

ULP Modules Per Circuit Breaker Range

The following table lists the compatible ULP modules for each range of circuit breakers.

Remote Controller

A remote controller is a device that is able to communicate with an IMU using a communication interface, such as the IFE Ethernet interface. For example, FDM128 Ethernet display for eight devices, supervisor, PLC, BMS, SCADA system, and so on, are remote controllers.

For the description of Modbus registers and commands, refer to the Modbus Communication Guides.
