Industrologic, Inc., announces the release of their SI51-8K Programmable Switch Input Controller.

The SI51-8K is now an option on Industrologic's popular SI51 that provides 8K of storage for Tiny Machine Basic programs and other data.

The Industrologic SI51-8K is a microcontroller based single board computer designed to be a complete industrial switch input controller assembly that is easy to program and connect to external signals. It includes not only a large bank of contact closure inputs, but a number of logic level input/output signals as well.

The board can be programmed as a standalone controller using its on-board Tiny Machine Basic programming language, or it can be used as an RS-232 serial data acquisition board.

The SI51-8K is based on the Atmel AT89C4051 microcontroller chip with EEPROM program memory, and can be reprogrammed using any number of software development tools and device programmers available for Atmel microcontrollers.

Communication with the SI51-8K is accomplished via a serial RS-232 port with true RS-232 interface and a DB9F connector that matches a PC compatible serial port pinout.

Convenient screw terminal block connections are used for all signals and power, which includes sixteen contact closure inputs and four logic levels signals usable as inputs or outputs.

One logic level signal is connected to a microcontroller interrupt signal to enable the board to capture short events or to count pulses.

The SI51-8K package is shipped complete with all items necessary to immediately begin application development, including a serial port cable for connection to a PC compatible computer, a wall block power supply, host computer software and programming examples, and hardware and software reference manuals.
