DR51 Single Board Computer


The Industrologic DR51 is a specialized single board computer that is easy to program and easy to connect to external signals. Its two 10 amp relays, eight logic level I/O signals (with keypad connector), and serial port make it an ideal interface for many industrial control, access control, home automation, and PLC applications. It can even be used as a universal keypad encoder and key to RS-232 converter.

The DR51's on-board power supply and its screw terminal connections make the setup for many applications both quick and simple. Plus, its RS-232 interface and simple commands means that it can be used as an RS-232 slave board for reading numerous types of I/O signals and controlling relays.

Included with each DR51 is a special version of Tiny Machine Basic (written specifically for the I/O on the DR51, and includes keypad instructions), development software, a wall block power supply, and a serial port cable to connect to your PC. An optional machined ABS plastic enclosure is also available.
