Power supply
The power supply unit is equipped with an I/O interface, which permits connection of the Beckhoff Bus
Terminals. The power is supplied via the upper spring-loaded terminals with the designations "24 V and
"0 V".
The supply voltage supplies the EK system and, via the terminal bus, the Bus Terminals with a voltage of 24
V
DC
(-15%/+20 %). The dielectric strength of the power supply is 500 V. Since the terminal bus (E-bus) only
transfers data, a separate power supply is required for the Bus Terminals. This is provided by means of the
power contacts, which are not connected to the power supply.
