The Industrologic IC51 is an Atmel AT89C51 microcontroller based single board computer designed to be a complete industrial controller assembly that is easy to program and to connect to external signals. It includes the versatile complement of input and output circuitry most commonly needed by common control applications.

The IC51 includes, pre-programmed into the microcontroller, a special version of Industrologic's simple programming language Tiny Machine Basic written for the hardware on the IC51, and the microcontroller chip can be re-programmed using any number of software development tools available for similar Atmel microcontrollers.

The IC51 is available as a complete circuit board assembly, and can be enclosed in an optional ABS plastic enclosure.
