2.8.2. Digital Input/Outputs (MFIO)

2.8.2.1. Digital Outputs (D-OUT)

[Warning]Warning

D-OUTs are NOT clean contacts. Pay attention to the circuit recommendations in the following sections.

Each one of the D-OUT[1..7] is an opto-isolated driver:

  • when activated (D-OUT[n]=1), it internally connects the corresponding pin to the "COM" pin

  • when deactivated (D-OUT[n]=0), its voltage level is floating, like an open circuit

It is necessary to implement an active circuit before connecting the D-OUTn to any actuator, i.e. an externally powered circuit that uses amplifiers and relays to drive lamps, motors, gate locks or other electric devices. The picture below shows the internal implementation of the D-OUT driver. +Vcc_OUT must be lower than 40VDC (in order not to damage the internal opto-isolator), while the current flowing from D-OUTn to COM must never be greater than 15 mA. Resistor Rc must be calculated in order to provide a max current of 15mA when the max voltage is applied. For example an Rc value of 2.7 KOhm is suitable for most applications.

D-OUT-driven circuit

[Warning]Warning

DO NOT INVERT THE POLARITY: voltage on D-OUTn must be always positive with respect to the voltage on COM! Do never allow more than 15 mA to flow from D-OUTn to COM! Do not apply a voltage greater than 40V to the resistor Rc!

2.8.2.2. Digital Inputs (D-IN)

[Warning]Warning

D-INs are NOT clean contacts.

Pay attention to the circuit recommendations in the following sections

Digital Inputs are opto-isolated too. They too must be driven using an externally-powered circuit as well as Digital Outputs.

Depending on how much current the circuit drives into the D-IN pin, the corresponding D-INn bit will return:

  • 0 when less than 10 uA flows from D-INn to COM

  • 1 when more than 1 mA flows from D-INn to COM

The picture below shows the internal implementation of the D-IN. Resistor Rd must be chosen considering the +Vcc voltage applied. The picture below shows the suggested Rd values at different +Vcc voltages. The current flowing from D-INn to COM must never be greater than 20 mA.

The maximum driving current supported by the photo diode is 20mA!
