5-24VDC SPI Signal Extension Receiver SA-R (White)

Description

The SA-R is a high-performance SPI signal extension receiver engineered to retrieve digital SPI control signals with precision and integrity at the far end of extended lighting control runs. Designed to work seamlessly within modern LED control systems, it operates on a voltage range from 5 to 24 VDC.

Key Features & Benefits

• Accurate Signal Reception
  Ensures reliable reconstruction of SPI (Serial Peripheral Interface) control signals—including data and clock lines—over long cable runs or in complex installations, preserving signal fidelity throughout.

• Wide Voltage Compatibility
  Compatible with voltages from 5 to 24 V DC, enabling flexible integration into diverse LED installations and power set-ups.

• Ideal Counterpart to the Transmitter
  When paired with the corresponding SA-T transmitter, the SA-R effectively completes the SPI signal extension chain, enabling consistent control across expansive layouts or segmented installations.

• Space-Efficient Integration
  With its compact form factor and minimalistic design, the SA-R neatly fits into space-restricted areas, simplifying placement and cabling.

• Modular, Scalable Design
  Built for scalability, multiple SA-R units can be used in tandem with transmitters to extend SPI control across large or modular lighting networks.

Typical Use Cases

• Large-Scale LED Installations
  Architectural façades, outdoor lights, and decorative displays where control signals must reliably reach distant or isolated LED segments.

• Multi-Zone & Segmented Lighting Systems
  Ideal for installations divided into zones that require synchronised SPI control across separate areas.

• Complex Lighting Projects
  Perfect for overcoming distance limitations or signal degradation by chaining extension receivers to maintain system integrity.

Technical Insight & Integration Tips

• Use in Tandem with SA-T Transmitter
  This receiver is intended to be placed at the far end of a long SPI control run, capturing and restoring the SPI (TTL DATA + CLOCK) signal delivered by the SA-T transmitter.

• Adaptable Voltage Use
  Whether your installation uses 5 V, 12 V, or 24 V, the SA-R accommodates the range without requiring additional power converters.

• Support for Chaining in Complex Layouts
  In installations that exceed a single signal span, multiple SA-T/SA-R pairs can be daisy-chained to maintain signal strength and synchronisation across all LED sections.

Summary

The Arc LED SA-R SPI Signal Extension Receiver is an essential component for maintaining signal quality and control fidelity in extended or complex SPI-based LED installations. Whether managing high-rise architectural lighting, expansive decorative displays, or multi-zone arrangements, the SA-R ensures that digital control signals arrive precisely and reliably. For best performance and reach, pair it with the SA-T transmitter, and consider chaining units as needed for scalable, robust lighting control.
