Abstract
A binary/digital input module implemented on an integrated circuit (IC) chip has a plurality of input channels and includes, for each input channel, a comparator coupled to receive a scaled input voltage and a scaled threshold voltage and further coupled to provide an output value and a digital isolation circuit for data coupled between the comparator and a respective output pin to provide the output value across an isolation barrier.
