M-DUINO 38AR I/OS PINOUT

M-DUINO 38AR I/OS PINOUT

M-DUINO 38AR I/OS PLC has different types of Inputs and Outputs.

It has 19 input/output signals:

  • 19 Inputs, of which:
    • 10 can be used as Analog Input 0-10Vdc, 10bits,(using Pins A0, A1, A2, A3, A4, A5, A6, A7, A8, A9). All of them can also be used as Digital Inputs.
    • 4 are Digital Input which can work as a Interrupt Input also. (using Pins 2, 3, 18, 19).
    • 5 are Digital Input (using Pins 22, 23, 24, 25, 26).
  • 19 Outputs, of which:
    • 5 are Digital Output (Using Pins 36, 37, 38, 39, 40).
    • 6 are Analog Output 0-10Vdc (Using Pins 4, 5, 6, 8, 10, 11), 8bits. All of them can also work as Digital Output and PWM output.
    • 8 are Relay Output 220Vac – 5A, (using Pins 27, 28, 29, 30, 42, 43, 44, 45).

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.
