The GE Multilin F35 UR Series is a type of universal relay with the model number F35-K03-HLH-F8L-H6E-M8L-P67-U6C-W67 that functions to provide protection and management for multiple feeders. Even though this specific F35 universal relay has a precise application and is tailored as such, it is still a member of the UR Series of GE Multilin universal relay system products. This means that is functions in generally the same way as other universal relay systems. The LAN ability is the local area network that a universal relay is able to communicate over for coordination with a programming device, an operator interface module, or another universal relay UR device. The universal relay obtains analog or digital input signals and then converts them into local signals within the universal relay by a CPU. This CPU is what coordinates with programming devices or operator interface modules using the LAN. After the CPU, these local signals are converted back to either analog or digital signals to go to control field devices. This basic setup applies to the F35-K03-HLH-F8L-H6E-M8L-P67-U6C-W67 Multiple Feeder Management Relay and other universal relays.
