What is the additional power consumption for Fieldbus interfaces on Bronkhorst® instruments

We offer a wide variety of possibilities for fieldbus interfaces, integrated on our flow and pressure meters/controllers. Typical, the additional power consumption for the interface boards is < 75 mA for instruments used at 15 V supply voltage and < 50 mA for units used at 24 V supply voltage.

Extra power consumption for onboard fieldbus interfaces

In the below table you can look up the exact values for each type of fieldbus.

Fieldbus	at 15 V supply	at 24 V supply
PROFIBUS DP	53 mA	30 mA
PROFINET	76 mA	48 mA
EtherCAT®	66 mA	41 mA
CANopen®	n.a.	48 mA
