Add part number 750-628 to your Quote. 750-628 CE
The internal data bus extension coupler module Add part number 750-628 to your Quote. 750-628 replaces the fieldbus coupler/ controller on an I/O module assembly. It is the counterpart to the end extension module Add part number 750-627 to your Quote. 750-627 . The connecting cable is plugged into the RJ 45 input socket, providing the logical connection to the fieldus coupler/ controller via the internal data bus extension end module Add part number 750-627 to your Quote. 750-627 . The extension does not interfere with the fieldbus coupler/ controller, all bus module system functions remain unchanged. The RJ 45 output socket allows further extension of the system (max. 10 stations).
The supply voltage for the field side and the internal electronics can be input separately. Both levels are electrically isolated from each other. Two diagnostic LEDs give information about the supply voltage for both the internal and field side. Two LEDs in the RJ 45 socket indicate fault-free communication with the bus coupler. The extension module can be used as the last coupler module in the system (switch on matching resistor) or as a bridge between two I/O module assemblies.

Installation Notes:
In order to guarantee safe operating conditions when using the internal data bus extension modules 750-627/-628, the buscouplers must have the internal parameters set accordingly.
