Features
WS2814 SPI DC 12 to 60v 4 Channel wallwasher and par light addressable decoder - Addressable Anything
This controller is designed to decode SPI (Serial Peripheral Interface) signals and provide
control over multiple output channels, likely for lighting applications such as LED strips or other
DC loads.
Key Features and Specifications:
● Type: SPI DECODER
● IC: WS2814
● Channels: 4 Channel
○ This indicates it can independently control four separate output channels.
● Input/Output Voltage: DC12~60V
○ This specifies the wide range of DC voltage that can be used to power the controller
and also the voltage that it can output to the connected loads. This flexibility allows
for integration into various power systems.
● Max Output of Current: 4 x 3A
○ This is a crucial specification indicating that each of the four channels can output a
maximum current of 3 Amperes. The total maximum current for the device would be
4 \times 3 \text{A} = 12 \text{A}, provided the power supply can deliver it. It's
important not to exceed the 3A limit per channel to prevent damage to the
controller.
Connections:
The controller features clear input and output terminals for both data and power.
Left Side (Data & Backup):
● Backup In: This likely refers to a backup data input, which can be useful for redundancy
in large lighting installations or for situations where the primary data line might be
interrupted.
● Data In: This is the primary input for the SPI data signal that the controller will interpret.
● Data Out: This provides a data passthrough or a buffered output of the input data signal.
This allows for daisy-chaining multiple decoders together, where the data signal from one
decoder feeds into the next.
● Backup Out: Similar to Backup In, this would be a passthrough for the backup data line,
allowing for redundancy in cascaded setups.
● GND (x2): These are ground connections, essential for completing the electrical circuits
for both data and power.
Right Side (Power & Channel Outputs):
● V+ (x2): These are the positive voltage input terminals for the controller and the loads.
The two terminals likely offer flexibility for wiring or to ensure sufficient power delivery.
● GND: Another ground connection for the power side.
● CH1, CH2, CH3, CH4: These are the four independent output channels. Each of these
channels will provide the controlled DC voltage (up to 60V) to the connected loads, with
individual current limits of 3A.
In summary, this SPI DECODER is a robust 4-channel controller capable of handling a wide DC
voltage range (12-60V) and delivering up to 3 Amperes per channel. It's designed for
applications requiring precise control over multiple DC loads via an SPI interface, with
provisions for data backup and daisy-chaining.
