In today’s fast-paced industries, real-time data and smart connectivity are now an essential commodity rather than an option. Moxa's remote I/O solutions are an example of the shift in the industrial landscape as they provide proactive intelligence, industrial-strength reliability, and out-of-the-box deployment. Moxa has designed its remote I/O solutions to help industry accelerate insights derived from field data while ensuring a stable connection with real-time access to that data. With Moxa, organizations will transition their operations from reactive to predictive in real time.

In a brief video, you'll see how Moxa's remote I/Os operate in the field with you, providing you with integrated field monitoring and better decision-making capabilities in real time, wherever you need them, whenever you need them.

Why Moxa

Proactive Performance

Moxa’s remote I/O devices are designed with event-driven push communication and Click&Go Plus Logic to move beyond traditional polling-based systems. This intelligent design eases the load on the host system and improves response times, contributing to the integration of IT and OT systems.

Event-driven push technology

In a push-based communication model, remote I/Os will send data only upon a change in their state—greatly reducing network traffic. Unlike polling, which constantly polls devices for change (which uses up a lot of bandwidth), push communication really allows the host to use bandwidth and provides it time to do real-time analysis and high-level applications. Models like the ioLogik E1200 Series, ioLogik 2500 Series, and MX-AOPC UA Suite support Moxa’s unique push technology.

Intuitive Click & Go Plus logic

Click&Go Plus Logic adds intelligence at the edge so that users can set up smart logic rules right on the device with an easy-to-use graphical interface. If-then-else logic allows you to respond to field events in real-time, rather than awaiting host instructions. The outcome is faster decision-making, lower latency, and greater overall system resilience, evident in various models, including the ioLogik 2500 Series.

Easy to Use

Moxa designs simplify installation by providing front-access wiring, daisy-chained Ethernet, and adaptable Modbus configurations to reduce effort and complexity in integration.

Image
Front Access Wiring

Moxa Remote I/Os take the hassle out of setup. The front-access wiring design provides direct access to screw terminals for quicker installation and a more organized use of space compared to rear wiring systems. All of this, plus more than 50% space savings on your DIN rail, gives you the option to save space for a large layout in compact or space-constrained control panels. You can witness this in certain models, such as the ioLogik E1200 Series, ioLogik R1200 Series, ioLogik 2500 Series, and ioThinx 4510 Series.


Supported Models:
ioLogik E1200 Series, ioLogik R1200 Series, ioLogik 2500 Series, ioThinx 4510 Series

Image
Daisy-Chain Networking With Dual LAN Ports

With dual LAN ports built in, some models, including the ioLogik E1200 Series and ioThinx 4510 Series, enable devices to be connected in a daisy-chained fashion without external switches. This simplifies your network design, reduces wiring costs, and makes deployment or expansion easier.


Supported Models: ioLogik E1200 Series, ioThinx 4510 Series

Image
User-defined Modbus address

Moxa remote I/O allows you to modify Modbus addresses for use in current configurations, so you can easily integrate with existing systems. This degree of user-customization intends to reduce rework, enhance speed for facility deployment, and enable the hassle-free and efficient integration of existing equipment. Some of the models equipped with this feature are the ioLogik E1200 Series, ioLogik 2500 Series, and ioThinx 4510 Series.

Impeccable Reliability

Moxa remote I/O devices are built for industrial robustness. Moxa remote I/O devices have a wide temperature operating range, meaning they are designed for extreme conditions, with tolerances from extreme heating to freezing. And for environments that have massive amounts of noise, they have enhanced RS-485 stability on select models like ioLogik R1200 that increases noise immunity by 137% for secure communications.

Where Remote I/Os Make an Impact

Moxa remote I/Os provide robust, compact control of lighting, roadside, and field systems across all forms of smart transportation, from tunnels to terminals, with products designed to operate in harsh outdoor environments.

Data Center

Moxa remote I/Os are great for thermal monitoring, legacy equipment integration, and energy management, as they support Modbus and SNMP protocols to easily connect with IT systems even in limited space.

Manufacturing

In terms of real-time process monitoring and machine diagnostics, Moxa remote I/Os provide flexible I/O combinations, quick implementation, and easy connection with SCADA or MES systems to make digitalization possible.
