ABSTRACT:
A combination input/output (I/O) module for a microprocessor based device is disclosed. The combination I/O module includes a combination point which is operable as either an input point adapted for coupling to an input device, an output point adapted for coupling to an output device, or both. The combination I/O module provides continuous sensing of the presence or absence of the output device. The combination I/O module includes a triac and provides for continuous sensing of the conductive state of the triac.
