9.8 Logic Equation (P121, P122 & P123)
The MiCOM P121, P122 and P123 relays integrate complete logic equations to allow
customization of the product based on customer application.
Up to 8 independent Boolean equations can be used (from A to H). Every result of equation
can be time delayed and assigned to any output relays, trip, trip latching and/or HMI LEDs.
Up to 16 operands can be used (from 00 to 15). Within operands, there are two parts:
−
(1/2) : logical gates (NOT, OR, AND, NOT AND, NOT OR)
−
(2/2) : signals (I>, tI>>, Input1 …etc)
