Fusion Expansion DPDT Relay Controller 24-Channel

24-Channel DPDT Expansion Controller for Fusion Series Controllers

This Fusion 24-Channel DPDT 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 6 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 Expandability

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 Expansion Port

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.

Controlling FXR Expansion Banks

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:

• Adds up to 256 Relays to a Fusion Series Controllers

• Mix and Match Relay Types to Suite your Application Needs
• Choose Between Mechanical and Solid-State Relay Types
• Choose DPDT Relays for Signal Switching Applications
• Automate All 256 Relays for Automatic Control using Base Station

Linking FXR Expansion Boards Together

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.

1-Amp DPDT Signal Relay Option

This controller offers an optional 1-Amp small signal relay, allowing control of low-power telecommunications signals up to 12VDC at 1 Amp. Ideal for audio, telecommunications, and very low power switching applications. This relay has a low On resistance. The 1-Amp signal relay is of the DPDT variety, which is the same as two SPDT relays that switch simultaneously, but remain isolated from each other. This relay has 6 total user connections, two of each of the following: Common (C), Normally Open (NO), and Normally Closed (NC). 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 16 AWG wire.

3-Amp DPDT Signal Relay Option

This controller offers an optional 3-Amp small signal relay, allowing control of low-power telecommunications signals up to 12VDC at 3 Amps. Ideal for audio, telecommunications, and very low power switching applications. This relay has a low On resistance. The 3-Amp signal relay is of the DPDT variety, which is the same as two SPDT relays that switch simultaneously, but remain isolated from each other. This relay has 6 total user connections, two of each of the following: Common (C), Normally Open (NO), and Normally Closed (NC). 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 14 AWG wire.

5-Amp DPDT Signal Relay Option

This controller offers an optional 5-Amp signal relay, allowing control of  signals up to 12VDC at 5 Amps. Ideal for audio, telecommunications, and light-duty power switching applications. This relay has a low On resistance. The 5-Amp signal relay is of the DPDT variety, which is the same as two SPDT relays that switch simultaneously, but remain isolated from each other. This relay has 6 total user connections, two of each of the following: Common (C), Normally Open (NO), and Normally Closed (NC). 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 14 AWG wire.
