The MMI 12 module is a current module for connection to an MMU 3 or an MMB 700. Up to 12 current channels can be measured with each MMI 12. The MMI 12 can be connected to a master device with a local bus connection using the RJ45 cable. With a maximum of 5 modules connected to each other, up to 60 currents (e.g. 20 x 3-phase loads) can be measured. The current inputs are designed for current transformers J3CT (3-phase current transformer set) or the JC (1-phase cable transformer) with 333 mV and offer a connection via plug-in contacts.
The unit is used for continuous monitoring of the currents in the feeders.
