A method and apparatus for collecting and distributing information to and from a computing element that is quickly scalable at the installation to varying types and numbers of signals. Standard sized modules (10) containing a generalized set of computation, discrete I/O, analog I/O, serial I/O, adaptable I/O, etc., or any combination thereof, provide the building blocks that can be attached to each other to provide the desired combination of functions. These modular components are mated to each other through a simple serial interface providing the inter-module communication interface and local power requirements. The modules are quickly stacked together and snapped in place in a manner supporting severe environmental conditions.
