What looks like a donut, but you can't eat it, yet it still gives energy?
Clearly, I’m not very good at riddles, so I’ll cut straight to the answer: a current transformer, or CT.

CTs are a critical part of any electrical load monitoring system, so let's take a look at how they work, the different types, how to size them, and lastly, two important aspects of installing them.

Join us in Houston for this year's ENTELEC Conference & Expo, May 9-11. Explore a complete edge solution for your project using Opto 22’s groov EPIC and RIO products with the efficient MQTT Transmission module from Opto tech partner Cirrus Link Solutions.

Watch the panel discussion from the 2022 Ignition Community Conference that brought together experts involved in the industry-changing State of Indiana Energy INsights project.

Dedicated readers of the OptoBlog (and we appreciate you!) might recall previous posts talking about our participation in a project that's changing the way manufacturers do business in Indiana. Introduced in a Cirrus Link Solutions webinar as well as outlined in a Control news article, the significance of this project can not be overstated.

Indiana is leading the way in advancing manufacturers to make Industry 4.0 quick, simple, and cost-effective. The state has launched a first-of-its-kind program to enable its manufacturing industries to become the Factories of the Future.

So it was no surprise when the project turned up as a panel discussion topic at this year's tenth annual Ignition Community Conference. Some industry names you might recognize came together for an important conversation.

Join Opto 22 and see groov EPIC in action at the one day ENTELEC Fall Seminar for the energy industry.

If your schedule allows you to be in the area of Odessa, Texas October 6th, you'll want to include the annual ENTELEC Fall Seminar in your plans. ENTELEC is a user association focusing on the convergence of telecom and IT including digitization, IIoT, automation, cyber security, AI, cloud and edge computing, specific to petroleum, natural gas, pipeline, and electric utility companies.

Their Fall Seminar is a one day conference designed to fit your schedule and priced to fit any budget. It's a well planned day offering new technology demos, industry training programs and networking opportunities, especially focused on the Energy and Oil & Gas industries.

A recent article featured in Control magazine outlines the project that brought together the state of Indiana and Amazon Web Services (AWS).

Indiana is leading the way in advancing manufacturers to make Industry 4.0 quick, simple, and cost-effective. The state has launched a first-of-its-kind program to enable its manufacturing industries to become the Factories of the Future.

This unique energy project brought together many key players including Energy Systems Network (ESN), Emerging Manufacturing Collaboration Center (EMC2), Amazon Web Services (AWS), OptoPartner Feyen Zylstra, and even Opto 22.

Better machine health, lower energy costs: see the financial and operational advantages in this new video.

Why isn't energy accounted for the same as other major business expenditures? It's time to change that. Opto 22's Director of Business Development, Arun Sinha, shows what you gain when you implement a plan to monitor and manage energy consumption and power usage.

Get some tips on using the groov RIO EMU with other Modbus TCP devices.

The Modbus protocol has been around since the late 1970’s. This is both amazing and cool. Amazing as some reading this have been using it since then (how time flies!). Cool because it's been around so long, and well established and widely used.

Opto 22 products have been supporting Modbus TCP since way-back-when. Out of the box, our devices are Modbus TCP slaves (now called "servers") and can be polled for data on specific register addresses. The groov RIO EMU (Energy Monitoring Unit), one of our newest products, is no different.

New website resources outline how to securely access and share your energy data.

Opto 22 gives you lots of options when it comes to helping you monitor your power and energy usage.  The groov RIO EMU (energy monitoring unit) is an edge I/O module meant for easy distributed power and energy monitoring of one 3-phase load. Check out our previous announcements for all the details.

However, for monitoring multiple loads located near each other, and for a complete system including real-time control, groov EPIC with power monitoring modules might be the better choice.

But, you might have more questions about which is the right solution for you, why and how do you get started monitoring your machine health or energy data? And how do you do it securely?

Check out our new website resources for some guidance on these important energy topics.

The world's leading association of energy operators is hosting its annual conference and expo this month in Houston.

Opto 22 is partnering once again with our Tech Partner Cirrus Link Solutions to exhibit and present at the 2022 ENTELEC Conference & Expo, April 26 - 28, 2022.  Cirrus Link President and CTO, Arlen Nipper, will be giving the keynote address on April 28th. You don't want to miss it!

Get insight on an exciting project that Opto 22 is involved in and hear from our Tech Partners about this groundbreaking Industry 4.0 and energy management endeavor.
