I/A Series Niagara: Schneider’s Niagara system, explained.
Schneider sells the same field controllers under two different servers. Here is what that means for your building — and why the choice matters more now that Niagara 5 is on the way.
We get some version of this question every month. “Wait — Schneider does Niagara too?”
It does. Most people know Schneider Electric for EcoStruxure Building Operation (EBO), its flagship building management platform. Fewer people know Schneider also sells a complete Niagara-based system under its own name. It is called I/A Series Niagara. (You may still see “TAC I/A Series” on older equipment and paperwork. The name has been around Schneider’s controls business for a long time.)
If you read our piece on what “Powered by Niagara” actually means, think of this as the Schneider chapter.
What is in the system.
The system has four layers, listed here from the top down.
- Niagara 4 Supervisor. This is the server, and it handles the enterprise-level work: trending and data logging, alarm routing with email notification and acknowledgement, master scheduling, dashboards, and archiving to external databases. Operators reach it from a standard web browser, and there is no cap on the number of users.
- JACE-8000 and JACE-9000. These are the supervisory controllers in the panel. A JACE integrates both IP and serial devices, which is why it is the workhorse on retrofits and legacy systems as well as new construction.
- SpaceLogic and EasyLogic field controllers. These are the controllers on the equipment itself. SpaceLogic controllers are native BACnet/IP, built for a full IP system. EasyLogic is the BACnet MS/TP version of the same family, for buildings that already have an MS/TP trunk worth keeping. Models cover air handlers, rooftop units, fan coils, heat pumps, plant equipment, and VAV boxes. The VAV models combine the controller, damper actuator, and airflow sensor in one package.
- Sensors and the commissioning app. SpaceLogic room and duct sensors cover temperature, humidity, CO2, VOC, pressure, flow, and current. Schneider’s Building Commissioning app handles device setup and I/O checkout from a phone, without waiting on the building network.
The part most people miss: same controllers as EBO.
Here’s the thing. The SpaceLogic and EasyLogic controllers in an I/A Series Niagara system are the same field hardware Schneider sells under EBO. The only difference is the server layer. EBO runs on Schneider’s own servers. I/A Series Niagara runs on a Niagara Supervisor and JACEs.
That changes how you should think about the decision. With most manufacturers, picking a platform means picking a hardware family. With Schneider, the controllers on your air handlers are the same either way. You are choosing the software that sits above them.
Why owners pick it.
- It is BACnet/IP from end to end. SpaceLogic controllers sit directly on the IP network, and SpaceLogic IP-IO expansion modules share their inputs and outputs with one or more controllers over BACnet. You get the speed and the diagnostics of IP all the way down to the VAV box.
- It is programmed in Niagara. SpaceLogic and EasyLogic controllers are programmed directly in Niagara Workbench, using script or the familiar wire-sheet blocks. There is no separate proprietary tool. Any Niagara-certified integrator can open the station and work on it.
- It also works with the MS/TP you already have. Not every building is ready to go all-IP. EasyLogic is built to expand and modernize an existing BACnet MS/TP network instead of replacing it. For a building with a healthy MS/TP trunk, that keeps the scope (and the budget) reasonable.
- It handles mixed buildings. The JACE was designed to integrate. Other manufacturers’ BACnet equipment and older serial devices come into the same Niagara station as the Schneider controllers.
- The security is current. Niagara 4 supports strong hashed passwords, TLS, certificate management, and BACnet Secure Connect. (If you have been following what happens when a BAS is left exposed, you know why that matters.)
I/A Series Niagara or EBO? How we call it.
Both are good systems. We install both. Here is the rough guidance we give owners and engineers.
If you are a mechanical engineer writing the controls spec, this is a good conversation to have during product selection, before Division 23 09 00 is locked. We help engineers with exactly that.
Niagara 5 is coming. Check your JACE.
Tridium is targeting general availability of Niagara 5 for December 2026. (Tridium’s dates are tentative and subject to change.) A few things are already clear from Tridium’s published Niagara 5 FAQ.
- The JACE-9000 will run Niagara 5. The JACE-8000 will not.
- Niagara 4.15 is the on-ramp. A station has to be on 4.15 before it can migrate to Niagara 5. Version 4.15 is the last Niagara 4 release, and Tridium plans to support it into 2028.
- Older Niagara AX systems take two steps. That includes older I/A Series installations. They go from AX to Niagara 4 first, then from Niagara 4 to Niagara 5.
- Mixed systems will keep working during the transition, as long as the Supervisor runs the newest version on site.
This is a planning item. If you have JACE-8000s or AX stations in your building, the next two years are your window to budget the change on your own schedule, instead of the day something fails. A Controls Baseline Report will tell you exactly what you have and what it will take.
Take the details with you.
Our two-page summary pulls the system, the EBO comparison, and the Niagara 5 timeline into one sheet you can pass along. Schneider’s own brochure has the product detail.
For the record.
We are a Tridium-certified Niagara integrator and a Schneider Electric EcoXpert partner, so we install I/A Series Niagara and EBO (and we will tell you honestly which one fits your building). We also work alongside mechanical engineers on controls design and specification.
If you have Niagara equipment you are trying to figure out — or a JACE-8000 you are now wondering about — email us. We will look at it. No sales call is required.
