Overview
Relay 4 Board allows you to drive four separate relays directly with MCU digital outputs.
Screw terminals allow you clean and easy connectivity, without need for additional soldering
IDC10 Connector enables systems to be easily connected to peripheral modules.
Description
Relay 4 Board is a plug-n-play, cost effective solution for adding relays to your device. Single ULN2803 driver IC with 8 Darlington arrays drives each of the four available relays. Screw-terminals allow you clean and easy output relay connectivity, and standard IDC10 connector is used for connection with development system. Using this board with your MCU you can turn on 220V lightbulbs, DC motors, or any other device that draws up to 16A of current and up to 250V. This board allows your device to jump over the boudary of output digital signals into the world of higher voltages and currents.
Features
- ULN2803 circuit drives four 12V high quality relays
- Relays can operate with 250V, 16A AC currents. Relays must be powered with 12V power supply which should be provided via CN2 screw terminal.
- Seven screw-terminals allow you safe and clean relays connectivity
- Signal LEDs for each relay help you to easy determine current relay state
- IDC10 connector simplifies connection to development system and target MCU
Benefits
- Cost effective solution for turning your prototype into simple PLC system
- High quality components and compact design allows you quick integration with existing systems
- Ready-to-use examples save development time
- Flexible solution suitable for all MCU architectures
- Board is clearly marked, which makes it easier to connect with external electronics
Examples
Examples that come with this board will show you how to connect and use the board with PIC, dsPIC, 8051 and AVR microcontroller. Each example contains detailed description and comments of the program. All examples can be downloaded from this page as well.
