The G3-JNC3 module consists of 3 RJ45 ports and a direct interface to the G-Mation G3 system bus and allows the extension of the EtherCAT automation network. The G-MATION system bus integrated in the G3-JNC3 module is the EtherCAT input port, while the 3 ports on the front of the module allow new EtherCAT devices to be connected to those on the bus.
The G3-JNC3 module requires no external power supply.
