RC5120 20 Relay Programmable Relay Controller
Add USB connectivity to your RC5120 for just $10 more with the USBCONV.
The Industrologic RC5120 programmable relay controller is a specialized single board computer that is easy to program and easy to connect to external signals. With its twenty 10 amp relays, logic level I/O signal, and serial port, it is ideal for many relay intensive industrial control applications.
The RC5120'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 easily used as an RS-232 serial data acquisition and control board!
Included with each RC5120 is a special version of Tiny Machine Basic (written specifically for the I/O on the RC5120), development software, a wall block power supply, and a serial port cable to connect to your PC. (Things you must purchase separately with everyone else's controller or single board computer.) An optional machined ABS plastic enclosure is also available.
