Low Power Vehicle Detector

  • Designed for solar powered applications.
  • Designed to be used with Diablo Controls’ free exit probe.
  • Will not interfere with other loop detectors.
  • Plug and play. Switchless and self-adapting to most common installations. Connect it up and watch it work.
  • Small profile, perfect for many installations.
  • Fail-secure operation.
  • Wide low-voltage operation.

Green Power LED: This LED blinks once per second to indicate the detector is powered and operating. In the case of an open in the input circuit, this LED flashes slowly (twice per second). This LED will flash fast (10 times per second) to indicate a shorted input circuit.

Red Detect LED: This LED will turn on for 125 ms when a vehicle is detected.

A fail-safe detector will output “detect” when the loop circuit is failed. On the free exit loop this will keep the gate open until the situation is fixed. This is useful in applications where it is important to allow traffic flow to continue. A fail-secure detector will never output “detect” when the loop circuit is failed. This will keep the gate closed. This is useful in high-security areas or installations where containment is needed. The DML-9LP is a fail-secure detector. Note: Never use a fail-secure detector on a safety loop.

Removable 7-pin terminal block. Pin assignments are shown below (from left to right):

1 – Relay Normally Closed (NC) - contact opens for 125 ms on detect

2 – Relay Common

3 – Relay Normally Open (NO) - contact closes for 125 ms on detect

4 – Power Common

5 – Power In (10 to 30 volts AC or +DC)

6 – Mini-Loop
