1. An isolated interface circuit for a modular energy system, the isolated interface circuit comprising:
a comparator comprising a first input configured to couple to a switch, a second input configured to couple to a reference voltage, and an output;
a duplicate comparator comprising a first input configured to couple to the switch, a second input configured to couple to the reference voltage, and an output;
an expander circuit comprising at least two inputs, wherein the output of the comparator is coupled to one of the at least two inputs of the expander circuit, and wherein the output of the duplicate comparator is coupled to other of the at least two inputs of the expander circuit, the expander circuit comprising an output;
an isolator circuit comprising an input and an output, wherein the input is coupled to the output of the expander circuit; and
a controller coupled to the output of the isolator circuit, wherein the controller is configured to:
compare the output of the comparator with the output of the duplicate comparator; and
determine activation or deactivation of a surgical instrument coupled to the controller based on the comparison.
