• 16 digital inputs
• Integrated web server to acquire the status of the digital inputs via browser
• Remotely congurable
• Connection by removable screw terminals

GENERAL DESCRIPTION
The SIO-MB16ND3 device is a Modbus TCP server with 16 digital input channels.
For the digital inputs, up to four 32-bit counters are available with measurement frequency of up to 300Hz.
The Ethernet interface allows reading and writing the values of the internal registers of the device in real time.
The built-in Web Server allows remote visualization, acquisition of the digital input states and access to the conguration parameters.
Signal LEDs for Ethernet activity, input state and power supply allow direct monitoring of the system.
Connections are made by removable screw terminals (inputs and power supply) and RJ45 plug (Ethernet).
The SIO-MB16ND3 is in compliance with Directive UL 61010-1 for the US market and with Directive CSA C22.2 No 61010-1 for the Canadian market.
The device has full electrical isolation between the lines, providing protection against the effects of ground loops existing in industrial applications.
It is housed in a tough self-extinguishing plastic enclosure which, thanks to its thin 22.5 mm prole, allows high-density mounting on EN-50022 standard DIN rail.
USER INSTRUCTIONS
Before installing the device, please read the “Installation Instructions” section.
To congure the device in INIT mode, refer to the User Guide. Connect the INIT terminal to the V- terminal (refer to the User Guide). Connect power supply,
Ethernet and digital inputs as shown in the “Wiring” section. The LED states indicate the working condition of the device; see the “Front Panel LEDs” table to
verify the device working state.
Instructions for conguration and calibration operations are contained in the User Guide.
To simplify handling or replacing of the device, it is possible to remove the wired terminals even with the device powered.

The device shall be mounted on DIN rail in a vertical and upright orientation.
For optimum operation and long life follow these instructions:
When the devices are installed side by side it is necessary to separate them by
the following minimum distances:
• 10 mm if UL certication is required.
• 5 mm if UL certication is not required.
Make sure that sufcient air ow is provided for the device. Avoid placing
raceways or other objects where they could obstruct the ventilation slits.
Avoid mounting the devices above appliances generating heat; ideally locate
them in the lower part of the panel.
Install the device in a place without vibrations.
Avoid routing conductors near power signal cables (motors, induction ovens,
inverters, etc.). Use shielded cable for connecting signals; ground shield at one
end only.
