[0017] The PCB board is also provided with an incoming wire socket 13 and an outgoing wire socket 14 on a third side 103 between the EtherCAT bus coupler fixed mounting side 102 and the one side 101, for power supply connection, bus connection, which is used for connection with a remote expansion module, which can be an EtherCAT bus-based remote analog input module, an EtherCAT bus-based remote digital output module or an EtherCAT bus-based remote digital input module.
