The electronics are housed in the Electronics Card Cage and control all machine processes.
Five subassemblies comprise the electronics:

•

The Power Module converts AC to DC power and controls the heater.

•

The Power Card provides low voltage power for the electronics.

•

The Processor Card houses the microprocessors and peripherals.

•

The Isolation Card provides interfaces to the patient and external devices.

•

The I/O (Input/Output) Card interfaces to the internal sensors and actuators.
