Molecular substrates can be viewed as computational devices that process physical or chemical 'inputs' to generate 'outputs' based on a set of logical operators. By recognizing this conceptual ...
A programmable logic controller (PLC) is an industrial solid-state computer that monitors inputs and outputs, and makes logic-based decisions for automated processes or machines. 1. The image above is ...
Modern object-oriented programming techniques are transforming PLC programming, making industrial automation faster to build, ...
Industrial digital inputs sample and serialize the state of eight 24-V current-sinking inputs under SPI or pin-based timing control, allowing for readout of the eight states via SPI. Here is an ...
The 74LVC257A is a quad two-input multiplexer with 5 V tolerant inputs/outputs and 3-state outputs. These 3-state outputs select 4 bits of data from two sources and are controlled by a common data ...
Fig 1. An SPI-based output driver (in this case, an L9822 octal relay driver from STMicroelectronics) can be used to provide a random mix of I/O pins at the chip’s output. The circuit in (a) senses a ...
