PLC Ardbox Analog 20 I/Os HF is based on an Arduino Leonardo board. 

It has 10 I/O (Analog 0-10VdC / Digital 5-24VdC).

The communications which provide are the following ones: USB, RS485 Half-Full Duplex (Modbus), I2C and SPI.

PLC Ardbox Analog HF has the following inputs/outputs:

Base
RIGHT Zone
Ardbox  Connector	Arduino Pin	Function
A0.6 A0.5 A0.4 A0.3 A0.2 A0.1 A0.0 Q0.9 Q0.8 Q0.7 Q0.6 Q0.5 Q0.4 Q0.3 Q0.2 Q0.1 Q0.0 (-) Com 24VCOM	3 5 6 9 10 11 13 0  1 7 3 5 6 9 10 11 13 – –	Analog Out Analog Out Analog Out Analog Out Analog Out Analog Out Analog Out PWM/digital Output PWM/digital Output PWM/digital Output PWM/digital Output PWM/digital Output PWM/digital Output PWM/digital Output PWM/digital Output PWM/digital Output PWM/digital Output Isolated GND Isolated Vdc Out

On the right zone there is a switch which configurate output configuration functions as a digital or analog mode(PWM).

On the left zone there is a switch where it can be set up some communication functions. 

In the front part there are all the LEDs to see the inputs/outputs that are working in that moment.
