Signal Power Interface (SPI)
£0.00Overview:
- The Signal Power Interface (SPI) provides PedSafety’s Guardian line with power by converting
the 120V in the pedestrian signal head to a safe 12V. “Walk” and “Don’t Walk” information is
read by the SPI and sent to a Guardian unit. - The SPI can be paired with a PedSafety WiAPB (Wireless Accessible Pedestrian Button) to
provide power to the button for a 0-wire WiAAPS system. - For intersections running off 48V, the SPI 48V is available and converts the 48V in the signal
pedestrian head to 12V.
