This Fusion 16-Channel SPST Solid-State Relay Expansion plugs into the Fusion FXR Relay Expansion Port to add more relays to your Fusion series dual interface relay controller. This controller includes 16 LED status lights and 2 heavy-duty screw-terminal connection points per relay. Configure the solid-state relays that best suite your application during checkout. This expansion may be powered by a 2.1mm 12VDC barrel connector or via screw terminals for direct wired power installations. On-board switcher regulator power supply runs cool and provides plenty of power for the logic of this design. FXR expansion input and output connectors allow it to mix anywhere on the chain of relay expansion boards. Mix different types of relays as your application requires.
Fusion Controllers know how to expand. Easily add Analog to Digital Converters, Contact Closure detectors, I²C devices, and a wide variety of sensors to meet your application objectives. The FXR Expansion Port allows you to also add expansion boards and control up to 256 relays.
Fusion Series Relay Controllers know how to connect to your application. With a simple point and click configuration, you can read a variety of sensors in just a few minutes. Fusion will automatically monitor your sensor in the background and make relay control decisions if a sensor is tripped or goes outside an acceptable range.
Fusion Series Controllers have 16 programmable I/O lines, which may be used for contact closure input, digital input, digital output, 8/10-Bit Analog to Digital Conversion, or I2C expansion. In most cases, these features may be mixed and matched as your application requires.
FXR Relay Expansion Controllers add a large variety of relay switching capabilities to an existing NCD Fusion series controller.
The FXR Expansion Port is used to add banks of external relays to a Fusion Controller. As we continue to develop new devices, a modular architecture will be implemented, offering the greatest amount of user flexibility.
FXR Expansion Boards have no on-board brains. They are entirely reliant on the brains of a “master” Fusion device. The FXR Expansion Modules have many possibilities:
FXR Expansion Controllers consist of a FXR Input and FXR Output Connector. Simply connect the FXR Output of your Fusion Controller to the FXR Input located on the relay expansion board. Chaining more relays is easy. Simply connect the FXR Output of your Fusion expansion board to the FXR Input of your next relay expansion. Mix and Match different relay types as your application requires.
We always include the 6″ expansion cables with your expansion board. We can provide longer cables if needed, but it’s important to keep the cabling as short as possible. Not all users will be able to expand to 256 total relays, as it all depends on the installation, the amount of electrical interference, and the overall cable length. For best compatibility, the total length of the Fusion controller and all of the expansions and cabling should not exceed 1 or 2 meters.

Solid state relays are ideal for agricultural switching applications, or remotely located switching. SSRs are frequently chosen to control pumps, valves, solenoids, lights, and other high-reliability applications. NCD solid-state relay controllers do not include solid-state relays, but you will have the option to choose the type of solid state relays you require when customizing your product. This controller is designed specifically to fit select Crydom solid-state relays, but may be compatible other solid-state relays made by other companies. Review Solid-State Relay Options
This video will guide you in determining which relay controller you need for your application as well as a general overview of the differences between Relay Options. If you’re new to our products or just need a refresher for a new application this is a great place to start.
Learn about Induction and how it comes into play with Relay Controllers. Induction suppression can make your Relay Control applications intermittent and unreliable. This video will show you what causes it, how to avoid it, and how to account for it in your application.
FXR and XR expansions are very similar, but are not directly compatible with each other. The FXR expansion port is an updated version of XR, which includes a right-angle connector to support our metal enclosures. The FXR cable is also capable of carrying I2C data. Because of the right-angle connector, the polarity of the cable is not compatible with XR expansions.
Fusion is capable of expanding to an absolute maximum of 256 Relays. In some cases, it may not be possible to control all 256 relays, particularly in applications where high noise levels may be involved. Experimentation may be required, as it is not possible for us to guarantee all users will be able to utilize all 256 relays in every application. Noise tends to accumulate when several expansions are connected together. For best results, the FXR expansion cables must be as short as possible. The typical total length of Fusion and all of its expansions and cabling should not exceed 1 or 2 meters.
Please examine the datasheet of each solid state relay carefully, as SSRs do not function exactly like mechanical switches. SSRs frequently have minimum load requirements, and some require external snubber circuitry for certain applications. SSRs do not typically work with volt meters in the same way as mechanical switches. SSRs must also be chosen for AC or DC applications, as they are not universally interchangeable. Some SSRs require forced air cooling, and may be damaged if not properly ventilated. Please consult the experts at Crydom.com if you are uncertain about your choice of SSR.
