Contact input and output modules

LINE DISTANCE PROTECTION SYSTEM – INSTRUCTION MANUAL

Each contact input/output module has 24 terminal connections. They are arranged in two

terminals per row, with twelve rows in total. A given row of two terminals can be used for

the outputs of one relay. There are options of using current or voltage detection for feature

supervision, depending on the module ordered.

All inputs and outputs are isolated from one another with each input and output having

two dedicated terminals. Since an entire module row is used for a single contact input or

output, the name is assigned using the module slot position and row number.
