M-DUINO 19R I/O PINOUT

M-DUINO 19R I/O PINOUT

M-DUINO 19R I/OS PLC has a diferents types of Inputs and Outputs.

It has 19 input/output signals:

  • 6 Inputs, of which:
    • 4 can be used as Analog/Digital Input 0-10Vdc, 10bits,(using Pins A0, A1, A2, A3). 
    • 2 are Digital Input which can work as a Interrupt Input also. (using Pins 2 and 3).
  • 11 Outputs, of which:
    • 8 are Relay Output (Using Pins  22, 23, 24, 25, 37, 38, 39, 40).
    • 3 are Analog Output 0-10Vdc (Using Pins 4, 5, 6), 8bits. All of them can also work as Digital Output and PWM output.

IMPORTANT: To enable communication connections the switches must be set to “OFF”. Set to “ON” position to enable I/Os terminals. Communications and I/Os terminals on the chart can not work simultaneously. For example if Pin 3 is enabled (OFF), I0.6 will not be disabled. See more on Switch Configuration.
