Safety information Carefully and fully read this user guide before installation and retain it for future reference. Qualified personnel The product described in this manual must be operated only by personnel qualified for the specific task and installation environment, in accordance with all relevant documentation and safety instructions. -
Page 6: Safety Instructions
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). - Page 7 WARNING 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.

Page 8: Introduction
Introduction Iono MKR 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 MKR ships without any Arduino board, so you can use your preferred Arduino MKR board, as far as it is fully compatible with the Arduino MKR pinout and fits the Iono MKR case. -
Page 9: Features
Features The Iono MKR key features are: ✓ 12÷28Vdc power supply, with surge and reverse polarity protection, and 1.1A resettable fuse ✓ compatible with 3.3V operating voltage Arduino MKR boards. Currently the following boards are supported: Arduino MKR WiFi 1010, Arduino MKR1000 WiFi (with headers), Arduino MKR ZERO, Arduino MKR GSM 1400, Arduino MKR FOX 1200, Arduino MKR WAN 1300 ✓... -

Page 12: Di5 And Di6 Digital Inputs
DI5 and DI6 digital inputs An external potential free contact can be connected between terminals VSO and DIx (x=5, 6); otherwise, the DIx terminal can be connected to an external voltage signal (in the 9÷40V range) referred to the GND of the Iono MKR module. DI5 and DI6 are connected to the Arduino board through a protection network. -
Page 13: Analog Output
DI5-DI6 JUMPERS POSITION Analog output Iono MKR features a 0÷10V output (AO1) which can be controlled by the DAC0 pin of the Arduino board; the 0÷3.3V range of the DAC0 pin is converted 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 14 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. These resistors can be enabled installing jumpers J2 and J1 respectively.

Page 16: Hardware Installation
Hardware Installation For the initial set-up, the plastic DIN rail case must be removed to access the circuit boards and internal connectors. The case also needs to be opened to connect a USB cable to the programming port of the Arduino board, and if the factory configuration of the internal jumpers for the RS-485 termination resistors or digital input configuration must be changed (see below). -
Page 17: Arduino Mkr Board Installation
Arduino MKR board installation To install your own Arduino MKR board in Iono MKR, or replace a pre-installed board, no tools are required. The Arduino MKR board top side pin headers (female) connect to the pin headers (male) of the top Iono MKR board. The Arduino MKR board is installed upside down, with the micro USB programming near the relay outputs terminal block. -
Page 18: Iono Mkr Software Development
Iono MKR software development Since Iono MKR is just a super-sized I/O shield for a standard Arduino MKR board, 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 19: Optional Components
Optional components Real Time Clock module Iono MKR can be shipped with an optional, factory-installed hardware real time clock with a dedicated long-life non-rechargeable back-up battery. The battery is only used to power the RTC chip when the main power is not available. Depending on operating conditions it should last up to two years if the Iono MKR board is not powered, more if the Iono MKR receives external power. -

KEEP OUT OF REACH OF CHILDREN. Swallowing may lead to serious injury or death in as little as 2 hours due to chemical burns and potential perforation of the esophagus. Immediately see doctor. Replace the RTC lithium battery before it is completely discharged. Replace the battery every 5 years even if the battery is still working properly. -
