Power distributor box
Beckhoff Automation has introduced the new EP9214 power distributor box designed to enable the local distribution and switching off of the power supply, providing the ability to supply up to four NEC class-2 circuits via typical M8 plug connectors. This I/O solution also provides complete diagnostics and control functionality for up to eight 24 V DC branch circuits (Us & Up power) per power box. Equipped with 7/8-inch plug connectors, it maintains a total current of 16 A for each control and peripheral voltage with cable cross-sections of 1.5 and 2.5 mm2 (roughly #14AWG). Even considerably higher starting currents are briefly permissible at the outputs, so that trouble-free start-up of the connected devices is guaranteed. Wiring in the field using the power distributor box is significantly simpler and less expensive than equipping the system with additional terminal boxes with fuses. The eight 24 V DC voltage circuits can also be separately switched on or off directly via EtherCAT in order to increase the energy efficiency of the plant.
