The Signal Power Interface (SPI) plays a crucial role in ensuring the reliable power and operation of PedSafety’s Guardian® product line, WiAAPS® product line, TLPI®, and Audible Beacon Device. It accomplishes this by efficiently converting the standard 120V power source or a 48V power source within the pedestrian signal head into a safe and manageable 12V supply. The SPI’s primary function is to retrieve and transmit the walk and don’t walk information to the connected product, thereby contributing to enhanced pedestrian safety.
The Input connections of our SPI (Signal Power Interface) present a robust and secure solution for pedestrian signal head wiring. These connections include 48 VDC or 89-134 VAC (depending on your SPI) fused and surge-protected inputs for walk, don’t walk, and AC neutral, ensuring reliable operation even in all conditions. On the output side, the SPI offers a straightforward connection to the corresponding terminal block with four wires, including power (+12VDC), – GND, walk, and don’t walk. SPI is designed for easy installation inside various types of pedestrian signal heads, providing a hassle-free setup. It boasts extensive transient protection and is encapsulated in UL94-V0-listed flame-retardant polyurethane, guaranteeing resilience.
