The Ardbox Relay is a PLC based on Open Source Hardware including Arduino Leonardo board. It has a 16MHz crystal oscillator and a micro USB connection.
This PLC can be powered at 12 – 24Vdc
The Ardbox Relay has 32KB (4KB used for the bootloader). It also have 2.5KB of SRAM and 1KB of EEPROM (Wich can be read and written with the EEPROM library) all from the Arduino Leonardo.
Input and Output
It has 20 input/output signals,
- 10 Inputs, of which:
- 6 can be used as analog Input 0-10Vdc,(using Pins A0, A1, A2, A3, A4, A5). All 6 can also be used as Digital Inputs.
- 4 are Digital Input which can work as a Interrupt Input also. (using Pins D0, D1, D2, D3).
- 10 Outputs, of which:
- 8 are Relay Outputs (220Vac, 5A max). (Using Pins D4, D7, D8, D9, D10, D11, D12, D13).
- 2 are analog Output 0-10Vdc. (Using Pins D5, D6).
This PLC has diferent types of communication ports,
- USB from the Arduino Leonardo board assembled inside.
- RS485, It is needed the pin D4,D7,D10,D11 which the Input/output function don’t work if the RS485 runs.
- RS232, It is needed the pins D0, D1 which the Input/Output function don’t work if the RS232 runs.
- I2C, It is needed the SDA, and SCL pins which are pins D2, D3 from Arduino Leonardo. The corresponding IOs don’t work if I2C communication is running.
- SPI, which use pins MISO (D14), MOSI (D16), SCK (D15), SS (D17).
- NOTE: Pins MISO, MOSI can work as Serial TTL port with Rx, Tx function.
It is possible to program the PLC with all available software to program Arduino Leonardo boards. See Software menu for more information.
Using Arduino IDE you can use the original Industrial Shields library.
