EK1132 | 2-port Power over EtherCAT junction

The EK1132 EtherCAT junction is based on IEEE standard 802.3af and supports power sourcing equipment (PSE), in order to ensure the supply of connected consumers (power devices, PD) via the four-wire standard EtherCAT/Ethernet cable. The PSE-PD supply voltage of 48 V is generated in the junction from the 24 V voltage used as industry standard. The maximum current input of the terminal devices is 350 mA. The signal and energy transfer takes places on the same wires, so that four-wire cables can be used. The Power over EtherCAT sensors are connected via a 4-pin connector, e.g. M12. The EK1132 uses the resistive power discovery procedure to determine whether the connected EtherCAT device supports Power over EtherCAT and to which performance class (as defined in the standard) it belongs. If Power over EtherCAT is supported, the supply is enabled. An intelligent power distribution system detects which consumer belongs to which performance class and distributes the total available power (15.4 W) to the connected devices accordingly. Like the 2-port EK1122 EtherCAT junction, the EK1132 also enables configuration of EtherCAT star topologies. Through TwinCAT and other suitable EtherCAT masters the EK1132 also supports coupling and uncoupling of EtherCAT devices during operation (Hot Connect). Plug X3 is included in the scope of supply.
