Descripcion larga:FEEDER TERMINAL
The REF541KM118AAAA is a feeder protection terminal manufactured by ABB for the protection, control, measurement and monitoring of medium voltage power grids

Hardware characteristics
Input/Output configuration: The REF541KM118AAAA typically has multiple on and off volumes that can be expanded to meet different application requirements. For example, the REF541 typically has 12 inputs (expandable to 22) and 5 sets of outputs (expandable to 10). It may also be equipped with 1 4-20mA input or output interface.
Man-machine interface: 17×19 row large LCD graphic display screen, and the LCD screen can be separated from the device, easy to install on the switch cabinet. The display language supports Chinese, English, French, etc., and can display information such as interval status diagram.

Communication interface: The REF541KM118AAAA has three communication interfaces, one for local communication with the PC and the other two for simultaneous communication with the substation automation system. Through different communication gateways, it can support a variety of communication protocols to realize the communication with upper-layer devices.
