The relay is equipped with six phase-current inputs and one neutral-current input or six phase-current inputs, one neutral-current input, three phase-voltage inputs and one residual voltage input. The rated level of the current inputs is 1/5 A and selectable in the relay software. The three phase-voltage inputs and the residual-voltage input covers the rated voltages 60...210 V. Both phase-to-phase voltages and phase-to-earth voltages can be connected. In addition, the binary input thresholds 16…176 V DC are selected by adjusting the relay’s parameter settings.
All binary input and output contacts are freely configurable with the signal matrix or application configuration functionality of PCM600.
As an option for standard configurations A, B, C and D, the relay offers six RTD inputs and two mA inputs. By means of the optional RTD/mA module the relay can measure up to eight analog signals such as temperature, pressure and tap changer position values via the six RTD inputs or the two mA inputs using transducers. The values can, apart from measuring and monitoring purposes, be used for tripping and alarm purposes using the offered optional multipurpose protection functions.
As an option for standard configurations E, F, G and H, the relay offers two RTD inputs and one mA input.
As an option a binary input and output module can be selected, having three high speed binary outputs (HSO), decreasing further the total operate time with typically 4...6 ms compared to the normal power outputs.
See the Input/output overview table and the terminal diagrams for more information about the inputs and outputs.
