... via a standard M8 sensor cable for data and power supply. This eliminates the need for separate and costly IP67 fieldbus connections. When the IP20 fieldbus coupler is replaced, the IP67 connection is automatically migrated to the new fieldbus. A total of up to 15 IP67 sub-bus modules can be connected over a maximum distance of 50 meters. This means that up to 120 signals from the field can be connected in the control cabinet in a space-saving manner with a footprint of just 11.5 mm.
