The MMI 12Flex module is a current module for connection to an MMU 3 or any other master device with a local bus connection. Up to 12 current channels can be measured with each MMI 12Flex. The MMI 12Flex can be connected to other devices with an RJ45 cable via the Local Bus interface. With a maximum of 5 modules connected to each other, up to 60 currents (e.g. 20x 3-phase loads) can be measured. The current inputs are designed for Rogowski coils (e.g. type KBU Flex) with an output signal of 333 mV.
The unit is used for continuous monitoring of the currents in the feeders.
