Boolean logic equation
The MiCOM P921/P922 & P923 relays integrate complete logic equations to allow
customization of the product based on customer application.
Up to 8 independent Boolean equations can be used. Each equation offers the
possibility to use AND, OR & NOT logical gates. Up to 16 parameters can be used
for each equation including any threshold and opto-input status. Every result of
equation can be time delayed, reused in another equation and assigned to any
output relays, trip, trip latching and/ or HMI LEDs.
Each boolean equation result can be alarmed or not.
