The DSP-100 vehicle detector has been specifically designed to handle most traffic applications and is very tolerant of noise and cross-talk conditions. Working on virtually any size loop, the DSP-100 tunes itself automatically and provides constant tracking to deal with environmental changes.  The DSP-100’s inherent noise filtering algorithms allow it to work reliably in almost any electrical situation.

The DSP-100 is available with a relay or solid-state output.  The “RT” and “ST” models have front-panel switches to select both extension and delay timing.  The operation of the timing functions can be modified by using the Delay Inhibit (also known as Phase Green) input.
