Energy module for driving multiple energy modalities

An energy module circuit for an energy module of a modular energy system, the energy module comprising a first port, a second port, a third port, and a fourth port, the energy module circuit comprising:

• a first circuit portion configured to generate a first electrical signal for driving an ultrasonic surgical assembly that is coupled to the first port;
• a second circuit portion configured to generate a second electrical signal for driving a bipolar electrosurgical assembly that is coupled to the first port;
• a third circuit portion configured to generate a third electrical signal for driving a monopolar electrosurgical assembly;
• a relay assembly coupled to the third circuit portion, the relay assembly configured to selectively transmit the third electrical signal to the first port, selectively transmit the third electrical signal to the second port, and selectively transmit the third electrical signal to the third port;
• and
• a fourth circuit portion configured to generate a fourth electrical signal for driving a bipolar electrosurgical assembly that is coupled to the fourth port.
