This Fusion 32-Channel SPDT 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 32 LED status lights and 3 connection points per relay. 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.
This product may have been previously manufactured using a part number shown below:
This controller is available with a 10-Amp relay option, allowing control of higher-power loads up to an absolute maximum of 240VAC at 10 Amps. Ideal for general purpose switching applications, this relays is focused on power-switching, and should never be used for low-power signals due to a higher On resistance of up to 150 Ohms when relay contacts are new (contact resistance drops to less than 1 Ohm after break-in period). The 10-Amp relay is of the SPDT variety, which provides Common (C), Normally Open (NO), and Normally Closed (NC) connections. Common is connected to NC when the relay is off. Common disconnects from NC and connects to NO when the relay is activated. All connections are made via screw terminals, capable of accepting up to 12 AWG wire. Review Datasheet
This controller is available with a 5-Amp relay option, allowing control of higher-power loads up to an absolute maximum of 240VAC at 5 Amps. Ideal for general purpose switching applications, this relays is focused on power-switching, and should never be used for low-power signals due to a higher On resistance of up to 150 Ohms when relay contacts are new (contact resistance drops to less than 1 Ohm after break-in period). The 5-Amp relay is of the SPDT variety, which provides Common (C), Normally Open (NO), and Normally Closed (NC) connections. Common is connected to NC when the relay is off. Common disconnects from NC and connects to NO when the relay is activated. All connections are made via screw terminals, capable of accepting up to 12 AWG wire. Review Datasheet

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.
