User Guide
Improper handling of lithium batteries can result in an explosion of the batteries and/or
release of harmful substances.
Worn-out or defective batteries can compromise the function of this product.
Replace the RTC lithium battery before it is completely discharged. The lithium battery
must be replaced only with an identical battery. See the "Replacing the RTC backup
battery" section for instructions.
Do not throw lithium batteries into fire, do not solder on the cell body, do not recharge, do
not open, do not short-circuit, do not reverse polarity, do not heat above 100°C and protect
from direct sunlight, moisture and condensation.
Dispose of used batteries according to local regulations and the battery manufacturer's
instructions.

User Guide
Introduction
Iono Pi is an extremely versatile I/O module that combines several digital and analog input
lines, support for standard interfaces like 1-Wire and Wiegand and power relay outputs,
typical of modern PLCs, with the powerful quad-core ARM Cortex-A53 64-bit processor of
the Raspberry Pi 3.
Iono Pi adds other important features that are essential to use the Raspberry Pi 3 for
professional applications, like a robust power supply with wide voltage range (9÷28Vdc)
capable of up to 2.5A output current at 5V to the Raspberry Pi board, and an optional real
time clock with lithium back-up battery (Iono Pi RTC version).
Iono Pi can be used for an incredible range of applications, from data acquisition and
control, to home and building automation, as well as access control, hotel room control
solutions, environmental monitoring and many others. Software development is pure
Raspberry Pi, with the constantly growing list of standard and proprietary software
frameworks available on this platform.
Iono$Pi$can be employed both in industrial and residential environments, for professional
applications where extreme reliability, ruggedness and compliance with technical and
safety directives are required.
While also available as an add-on board, the fully assembled version is packaged in a
compact DIN standard case with omega-rail mounts, and certified to the relevant
standards, ready for use in professional installation.
The information contained in this manual covers all versions, except where explicitly stated
otherwise. The bare board is called “Iono Pi board”, while the assembled unit is simply
“Iono Pi”.

User Guide
Hardware Installation
Iono Pi board
The Iono Pi board is supplied with all connectors pre-installed. No soldering is required.
You should connect Iono Pi to Raspberry Pi aligning the GPIO connector. Use appropriate
turrets/spacers to firmly bolt the two boards together, ensuring that no conductive part of
one board touches any part of the other board.
Be particularly careful to ensure there is enough clearance between the Ethernet and USB
connectors and the bottom of Iono Pi’s circuit board.
The GPIO connector of the Iono Pi board must be perfectly aligned to the Raspberry Pi's
GPIO pins. Turning on the Raspberry Pi and/or the Iono Pi board with the GPIO not
correctly connected will damage both the Raspberry Pi and Iono Pi board.
Iono Pi
The Iono Pi module comes pre-assembled with a Raspberry Pi 3 Model B or B+ board, in
a plastic standard DIN-rail case.
There is no need to open the case, unless you have to change the position of the jumpers
that select the voltage level of the TTL/DI inputs (see below), or to replace the internal
battery.
The Micro SD card (not provided) can be inserted through a small opening on the side of
the case. Use a small pen or paper clip to gently push the card in its slot.
Replacing the RTC backup battery
Iono Pi has an optional hardware real time clock with a dedicated long-life non-
rechargeable back-up battery.
The real time clock optional board is shipped with a replaceable Lithium / Manganese
Dioxide (Li/MnO2) battery installed.
The battery is only used to power the RTC chip when the main power is not available
(when the Raspberry Pi is off). Depending on operating conditions it should last up to two
years if the Iono Pi board is not powered, more if the Iono Pi receives external power.
Improper handling of lithium batteries can result in an explosion of the batteries and/or
release of harmful substances.
