Supply Voltage - MICRO-EPSILON IF2035-EtherCAT Manual

4.2.2

Supply voltage

The supply voltage is daisy-chained from the supply port (terminal 1) to the sensor port (terminal 2), i.e., the supply volt­
age must match that of the sensor. Positive voltage must be between 9 V and 36 V.
► Connect the inputs
The voltage supply must match that of the connected sensor, because the voltage is internally daisy-chained.
Micro-Epsilon recommends using the optionally available power supply unit PS2020, input 100 - 240 VAC, output 24
VDC/2.5 A, see Appendix.

i If the distance between IF2035-EtherCAT and the connected sensor/controller is long, Micro-Epsilon
recommends that a separate supply be used for the sensor/controller.
