The IC51 is designed to be a complete industrial controller assembly. It includes a versatile complement of the input and output circuitry needed by many common control applications.

The IC51, which is based on the AT89C51 microcontroller, can be reprogrammed using any number of software development tools and device programmers available for Atmel microcontrollers. You can program the board as a stand-alone controller using its on-board Tiny Machine Basic programming language, or you can use it as an RS-232 serial data acquisition board.

Communication is accomplished via two serial ports with true RS-232 drivers and DE-9 connectors matching PC-compatible serial port pin outs. The IC51 includes a real-time clock/calendar chip with on-board battery backup and registers that are integrated into the variables of the Tiny Machine Basic language.

Convenient screw terminal blocks are used for all of the digital, analog, and relay connections, which include eight 10-A form C relays, eight logic levels signals that you can use as inputs or outputs, eight digital outputs, and eight 12-bit A/D inputs. Its on-board power supply has a wide input range and includes 5- and 12-V outputs at the screw terminals for use by external devices.

The IC51 features LCD support circuitry that interfaces to a 16-pin 0.1" header connector, matching most LCD module connections. It also has an on-board contrast potentiometer for the LCD module. Included in the Tiny Machine Basic language are LCD commands that make it easy to display information on an LCD module.

The IC51 package is shipped complete with all the items necessary to begin application development immediately: a serial port cable for connection to a PC, a wall block power supply, host computer software and programming examples, and hardware and software reference manuals.

The IC51 costs $159. An enclosure costs $30.
