RC51 8 Relay Programmable Relay Controller - $139

RC51 Enclosure - $30

The Industrologic RC51 is a microcontroller based programmable relay controller designed to be a complete industrial controller assembly that is easy to program and connect to external signals. It includes a large bank of high current relays as well as digital input circuitry needed by many common control applications. The RC51 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.

• Based on the Atmel AT89C4051 microcontroller operating at 11.0592 MHZ
• Convenient screw terminal block connections for all relay and digital I/O connections
• Serial RS-232 port with true RS-232 interface and DB9F connector matching PC compatibles
• Eight 10 amp Form "C" relays with LED indicators for on/off status
• Four digital logic levels signals usable as inputs or outputs including one interrupt signal
• General purpose software readable pushbutton switch and software controllable LED
• 512 byte EEPROM for storage of small programs or configuration information
• On-board +5 volt power supply including screw terminal connection for external circuitry
• Pin-type power connector for easy connection to wall block power supplies
• Tiny Machine Basic programming language for the RC51 programmed into the microcontroller
• EEPROM based AT89C4051 can be reprogrammed using common Intel 8051/Atmel AT89Cxx51 software development tools and device programmer

The RC51 package is shipped complete with all items necessary to immediately begin application development:

• The RC51 circuit board
• A serial port cable for connection to a PC compatible computer
• A wall-block power supply
• Host computer software and programming examples
• Hardware and software reference manuals
