DSP-55 Diablo Vehicle Loop Detector

Diablo Vehicle Loop Detector, 10 to 30AC/DC Input

The DSP-55 detector is intended to be a full-featured single channel detector that can work with both inductive loops as well as the new Diablo Controls mini-loops. Many features have been included which are normally found only on more expensive models. The small package is powered by a high-performance 8-bit microcontroller that does not skimp on performance. The DSP-55 detector has a small footprint and was designed to retrofit into many existing locations that may require a detector upgrade. This allows maintenance personnel to carry only one detector to meet most, if not all, of their vehicle detection needs.

The detector uses a 10-pin Molex connector for its connections and has three solid-state (open-collector) outputs. The solid-state outputs allow for a smaller total package size, lower power consumption, and elimination of contact bounce.

The DSP-55 is a compact vehicle detector that will operate on any voltage from 8 to 35 volts DC. The low voltage range is ideal for solar applications. The DSP-55 can be connected to a standard inductive loop or one of Diablo Controls mini-loops. The Diablo Controls mini-loop is a small “pipe shaped” device approximately 4-1/2” by 1” and is designed to be buried in the ground to detect vehicles. Contact Diablo Controls for more information on the mini-loop. The DSP-55 can be used as either a safety loop or free exit loop detector. It should not be used as a safety loop if used with a mini-loop. It also has the flexibility to be either “fail-safe” or “fail-secure”. The DSP-55 has three solid-state FET outputs called A, B and -B outputs. The two B outputs are “normal” and “inverted”. These combinations of outputs allow for the DSP-55 to be easily interfaced to a wide variety of control boards. The DSP-55 has 10 selectable sensitivity settings and uses a 10-position DIP switch to configure the detector. This includes delay or extension timing functions and pulse on entry or pulse on exit features. This makes the DSP-55 very flexible and versatile for those installations that need a little more than a standard detector.
