Allows you to extend the number of connected peripheral iNELS units
External master MI3-02M provides expansion of the amount of units iNELS3 connected to the central unit CU3-01M or CU3-02M of two other lines of BUS (i.e. about 2x32 peripheral units).
Through the system BUS EBM, it is possible to connect to one central unit up to 8 external masters MI3-02M.
Combining central unit CU3-01M (02M) and 8 external masters MI3-02M we can reach maximum capacity of iNELS system up to 576 peripheral units.
If you require an extended system then it is possible to use communicationof up to 8 central units with Connection server using ELKONET protocol, eventually the integration of more central units into BMS via ASCII protocol.
MI3-02M have marked on the front panel of the unique hardware address. This address belongs to the line BUS1. Hardware address of BUS2 line is always one value higher than for BUS1.
To power the lines BUS, it is necessary to use a BUS separator BPS3-02M or BPS3-01M (supply only one line).
Status signaling of each BUS (operation, fault) is indicated by twocolor LEDs on the front panel of the module.
The last MI2-02M connected to the EBM BUS must be closed with a 120 Ω termination resistor. This part adapted to be inserted between terminals is included into central units packages and it is necessary to insert between terminals EBM+ and EBM-.
MI3-02M in 1-MODULE version is designed for mounting into a switchboard, on DIN rail EN60715.
