The F35 UR Series Universal Multiple Feeder Management Relay F35-G00-HKH-F8R-H6N-M8R-P6N-UXX-W6N is a Multilin universal relay with modules found in the rack that are specified in the model number by three digit alpha numberic codes. The first letter indicates the position of that module in the universal relay as a whole and the next two digits are the order option of a certain module type. For example, the Digital I/O modules will either have a two digit code that begins with a ‘4’ or a ‘6’. In this case with the Multiple Feeder Management Relay F35-G00-HKH-F8R-H6N-M8R-P6N-UXX-W6N, there are three 6N codes occurring in the part number. This means that this feeder management universal F35 relay actually has three digital I/O modules that are of the same description in terms of the order specification. The 6N order option allows the digital I/O module to have four Form-A outputs and eight digital inputs. The outputs have the option to come with monitoring current or monitoring voltage capabilities. In this case, the 6N order option does not have either additional monitoring ability.  Thus this UR does not have that digital I/O module characteristic in any of the three digital I/O module locations.
