The present technology provides for an IO module system (e.g., an industrial control system) that can provide multiple-channel analog and digital interfaces to a number of sensor devices of different types, where each channel of the IO module is programmably configurable as a digital input, a digital output, an analog input, and an analog output. Each sensor interface is implemented on an individual channel basis using discrete components in communication with a microcontroller. The present technology enables the rapid implementation of an IO channel operable in a wide range of voltage and current modes needed for common sensor interfaces.
