    3.1. Power Supply The units require a DC supply from 17 to 30 volts which must be applied to terminals 1 and 2. Depending on the input voltage level and internal states, the power consumption may vary and lies in a range of about 70 mA with a 24 volts input (plus encoder currents taken from the auxiliary voltage output).
