EP9224-0023 | 4/4-channel power distribution for EtherCAT Box modules with current measurement/data logging

The EP9224-0023 enables connection of four EtherCAT Box power supply branches. In each 24 V branch the current consumption for the control voltage US and the peripheral voltage UP is monitored, limited, and, if necessary, switched off.

The input voltage and current values of all outputs can be evaluated via the process data. A continuous data log of the relevant data can be retrieved when an error occurs in order to localise the cause of the error.

The power distribution is supplied via a 7/8" connector with up to 16 A (per voltage supply US/UP). Several modules can be configured in a cascade arrangement. In the event of a short-circuit in one of the four (eight) outputs, the affected output is switched off. The supply for the other branches remains active. The switch-off and control is done in such a way that the input voltage does not fall below 21 V. During startup consumers with large capacities can be added without problem.

The master can read diagnostic messages from the individual channels via the EtherCAT interface. Independent switching of individual consumer branches is also possible via the EtherCAT master.
