MMU 3
The voltage module MMU 3 serves as an alternative basis of a modular measuring system if no master with local bus connection (e.g. MMB 700) is available or if an additional voltage has to be measured.
Up to 5 MMI 12 current modules can be connected to it and the measured values can be tapped via the RS485 interface.
Application
The unit is used for continuous monitoring of the voltages for the arranged MMI 12.
