External master BUS with Ethernet communication
MI3-02M/ETH

Description

• The external master MI3-02M/ETH enables the expansion of the number of connected iNELS3 peripheral units to the central unit CU3 by another two branches of the installation BUS (by 2x 32 peripheral units).
• The unit can communicate with the CU3 central unit via the EBM system bus or via Ethernet.
• Up to 8 pcs of MI3-02M/ETH can be connected to one CU3 via
  the EBM bus.
• The unit MI3-02M/ETH is powered by a PS3-100/iNELS or PS3-30/iNELS power supply.
• The status of each branch of the installation bus BUS (run, error), EBM and ETH is signaled by the corresponding color LED on the front panel of the unit.
• If this is the fi rst or last unit on the EBM system bus, the line must be terminated with a resistor with a nominal resistance of 120 Ω.
• MI3-02M/ETH is a 1-MODULE version, designed for mounting in a switchboard on DIN rail EN60715.
