CU3-10M is one of the basic system control units of iNELS BUS installations.

The unit can work independently, as an autonomous project, or it can be controlled by the IP-MASTER as part of a larger project.

The unit is equipped with one BUS to switch it is possible to connect up to 32 elements from the iNELS BUS portfolio.

The current load of one line is max. 1 A. BPS3-01M with 3 A can be used in the case of a connected device with more than 1 A.

The CU3-10M system unit is equipped with one Modbus system bus. The Modbus system bus allows control of Modbus thermostat and Air condition units (RS-485).

The RJ45 100 Mbps Ethernet connector is used for direct communication with the cloud for mobile app control or for communication with the superior unit within the iNELS IP topology.

Configuration takes place in the iNELS3 Designer & Manager software (iDM3). Through iDM3 it is possible to update the firmware of central units and bus connected peripheral units.

The central unit is implemented with MQTT protocol for 3rd party communication.

The unit is powered by 27 V DC from iNELS power supply.

System units CU3-10M in 1-MODULE design are designed for mounting into a switchboard on DIN rail EN60715.
