Page 7: Introduction
Introduction Iono Arduino combines the ease of use of the Arduino platform with multiple input and output interfaces; the result is a rugged, safe, reliable and easy to connect module, suited for installation both in industrial and residential environments. Iono Arduino is available in three versions, all using the same shield board and case, but with different Arduino boards pre-installed. -
Page 8: Features
Features The Iono Arduino modules key features are: ✓ 12÷24Vdc power supply ✓ compatible with 5.0V and 3.3V operating voltage Arduino boards ✓ 4 multi-mode inputs: either to be used as digital or as 0÷10V or 0÷20mA analog signals ✓ 2 digital inputs for potential-free contacts ✓... -
Page 9: Usage And Connections
Usage and connections FIGURE 1 CONNECTION EXAMPLE Power supply Iono Arduino can be powered with DC voltage only: ✓ DC: nominal voltage in the range 12V to 24V (MIN=11, MAX=30Vdc) Respect the correct polarity shown in the schematic diagram (+ -). The power supply circuit implements reverse polarity protection using an auto resetting fuse and surge protection up to ±500V/2ohms 1.2/50μs. -
Page 10: Multi-Mode Inputs: Analog Mode
Multi-mode inputs: analog mode Iono Arduino features 4 multi-mode inputs (1, 2, 3, 4). Depending on terminal blocks wiring, digital (ON-OFF), analog 0÷10V or analog 0÷20mA signals can be applied. When using analog inputs, 0÷10V and 0÷20mA are converted to 0÷3.3V levels in order to be compatible with the Arduino platform input pins. -
Page 11: Analog Output
J1-J2 JUMPERS POSITION Analog output Iono Arduino features a 0÷10V output (AO1) which can be controlled by the PWM function of the Arduino platform; the 0÷100% duty cycle of PWM signal corresponds to a 0÷10V output voltage. This is a sink/source output (the current direction at this output can be both positive and negative). -
Page 12: Mapping
The RS-485 TX/RX switching is implemented automatically in the Iono’s micro-controller, based on speed and number of bits detection, and is completely transparent to the software controlling the UART on Arduino. The RS-485 line has 620 Ohm pull-up and pull-down resistors on lines A and B. The biasing resistors ensure that, during idle periods the data lines are kept at a stable voltage level and prevent false triggering of receiver input. -

• -: no rule - no control rule set for this relay. Press 5 to review the configuration and confirm to save it. When the new configuration is saved, Arduino will automatically reset and restart with the new configuration. The configuration is permanently stored in the Arduino’s EEPROM memory, and retained across restarts and power cycles. -
Page 19: Analog Inputs And Digital Counters
Reading addresses 101 to 106 returns the value of the input pins filtered with a de-bounce function. This filter has a 50 ms time constant, so that a value change is reported only after being stable for at least 50 milliseconds. Reading addresses 111 to 116 returns the instantaneous value of the input pins, with no de-bounce filter applied. - Page 20 incremented by one (and rolled back to 0 after reaching 65535) on the positive rise of their respective inputs, after the de-bounce filter.

Page 23: Iono Arduino Software Development
Iono Arduino Software Development Since Iono Arduino is just a super-sized I/O shield for a standard Arduino, you don’t need any specific library to work on it. Our libraries and examples, available with source code on GitHub, will provide you with some handy utilities to speed up your development, including functionalities to monitor the inputs (filtering out possible noise) and control the outputs, HTTP APIs, Modbus support and much more. - Page 24 FIGURE 5 USB ADAPTER CONNECTOR AND RESET BUTTON Insert the USB Serial Adapter as shown below, with the components side facing down. FIGURE 6 SERIAL ADAPTER CONNECTED TO THE ARDUINO BOARD Connect the adapter to a PC and perform the programming as usual. This operation does not require the Iono Arduino module to be connected to a power supply.
