Wago-750-628
Data bus expansion coupler module

Bus extension coupler module; Light grey


The coupler module for the internal bus extension module 750-628 replaces the fieldbus coupler/controller at the I/O terminal. The termination module is also the matching part for the 750-627. Plug the connecting cable into the upper RJ-45 socket to establish a logical connection to the fieldbus coupler/controller via the termination module 750-627. The expansion is completely transparent to the fieldbus coupler/controller. All functions of the I/O module system are retained without any changes. Additional expansion to the system is provided by the lower RJ-45 socket. This allows the entire system to be expanded in 10 stages.

The supply voltage of the field side and internal electronics can be supplied separately. Both levels are electrically isolated from each other. Two diagnostic LEDs provide information on both the internal and field side supply voltage. Two LEDs on the input socket indicate error-free communication with the bus coupler. The expansion module can also be used as the last coupler module in the system (turn on the matching resistor) or as a bridge between two I/O modules.

To ensure safe operation when using the internal bus expansion module 750-627/-628, they must be registered with the following couplers and controllers (including all versions) (750-304, 750-306, 750-310, 750-319, 750-324, 750 -333, 750-337, 750-340, 750-342, 750-370, 750-804, 750-806, 750-819, 750-830, 750-833, 750-837, 750-841, 750-842 , 750-849). For this purpose, the "WAGO Extension Setting" software must be used (download: www.wago.com).

We would like to remind you that only one termination resistor can be activated in the entire system.

When updating firmware and internal operating parameters, please fill in the production number matrix located on the right side of the couplers.
