Connections#
Connection to MIVO Connect
The Expansion port contains both hazardous voltage and communication. Always make sure the MIVO Connect system is disconnected from the power source before any expansions are connected or disconnected to or from the system. The included cables must not be extended or modified in any way.
The MIVO Connect system is equipped with an expansion port to expand the capabilities of the system with one or more external interfaces. The expansions are attached side by side and use the included cable to power and communicate with the expansions. A longer cable (60 cm) is available from the manufacturer to continue the system on another row in the cabinet.
The expansion port is designed for up to 10 expansions on every MIVO Connect.
M-Bus#
The MIVO MBUS Extender 256 is designed to power up to 256 standard MBUS loads. Typically, one sensor or meter consumes one load, but in some cases, they may require more. Please consult the datasheets for specific sensors or meters for more information.
The MBUS connections are non-polarized, meaning that the bus operates regardless of which cable is inserted into each terminal (there is no positive or negative orientation). The MBUS ports are also galvanically isolated from the rest of the system.
The device is equipped with three connection terminals for ease of connection, and all terminals are internally connected. Each terminal supports cables from 0.2 to 1.5 mm².
