The D60-K03-HKH-F8L-H6D-M67-P67-U6H-W67 is a Multilin D60 distance protection relay of the universal relay system. This unit affords the user with may benefits that are universal to all D60 protection relays. For example, the D60-K03-HKH-F8L-H6D-M67-P67-U6H-W67 has phase and ground distance protection that is high-speed and five zone quad or mho. On compensated lines this protection is characterized as being reliable and secure. The base unit for the D60-K03-HKH-F8L-H6D-M67-P67-U6H-W67 is similar to the D60 distance protection relays. In addition, this unit has the RS485 + multimode ST Redundance 100BaseFX CPU as indicated by D60-K. The software option included is the IEC 61850 (03).
The user interface is the vertical front panel with the English display (F) and the CT/VT DSP is 8L, which is a standard 4CT/4VT with enhanced diagnostics. This option is in comparison to the 8M which has sensitive ground 4CT/4VT with enhanced diagnostics. The W67 order code also shows that this Multilin D60 D60-K03-HKH-F8L-H6D-M67-P67-U6H-W67 has a Digital I/O characterized by 8 Form-A outputs (no monitoring). 

The Multilin D60-K03-HKH-F8L-H6D-M67-P67-U6H-W67 distance protection relay does use FlexLogic to provide the operator with the ability to create custom schemes for control and protection. The D60 contains up to 1024 lines of FlexLogic.
