Safety instructions
General safety instructions
Protect the unit against moisture, dirt and any kind of damage during transport, storage
and operation. Do not operate the unit outside the specified technical data.
Never open the housing. If not otherwise specified, install in closed housing (e.g.
distribution cabinet). Earth the unit at the terminals provided, if existing, for this purpose.
Do not obstruct cooling of the unit. Keep out of the reach of children.
Life threatening voltages are present within and around an open control cabinet.
When installing this product in a control cabinet or any other areas where dangerous
voltages are present, always switch off the power supply to the cabinet or equipment.
Risk of fire if not installed and operated properly.
Follow all applicable electrical safety standards, guidelines, specifications and regulations
for installation, wiring and operations of this product.
The Raspberry Pi board could generate a substantial amount of heat when the software
forces the CPU and/or GPU to operate at high load levels. Ensure that the product is
properly installed and ventilated to prevent overheat.
The connection of expansion devices to this product may damage the product and other
connected systems, and may violate safety rules and regulations regarding radio
interference and electromagnetic compatibility.
Use only appropriate tools when installing this product. Using excessive force with tools
may damage the product, alter its characteristics or degrade its safety.
Battery
Iono Pi RTC uses a small lithium non-rechargeable battery to power its internal real time
clock (RTC).
WARNING
WARNING
NOTICE

Iono Pi 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.

Iono Pi 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 ARM processors of the Raspberry Pi Model B
version 2, 3 and 4.
Iono Pi adds other important features that are essential to use the Raspberry Pi for
professional applications, like a robust power supply with wide voltage range (9÷28Vdc)
capable of up to 4.0A output current at 5V to the Raspberry Pi board, a real time clock with
lithium back-up battery and an embedded Microchip ATECC608A secure element chip.
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”.
