MENTOR 12 is IEC‐61850 compatible. The option MENTOR IEC 61850 is a GOOSE Messages Interface Board which consists in a plug & play electronic board that installs into the Control Bus of any MENTOR 12 unit just by sliding it inside. The configuration software tool is included in the MENTOR 12 internal software, avoiding the use of an external computer, and allows to subscribe/publish the GOOSE messages.

This option works through the RJ‐45 connector, which connects with the IEC‐61850 bus and use the information contained in the GOOSE messages as logic inputs and also it is able to broadcast GOOSE messages that acts as logic outputs, exactly in the same way that the current MENTOR 12 electrical I/O works, but avoiding the wiring of the I/O to the relay inputs and outputs. The IEC 61850 option can be installed in any existing or future MENTOR 12.
