DIABLO DSP-20-117, DUAL CHANNEL VEHICLE DETECTOR

• Directional Logic.
• Advanced technology with superior noise tolerance.
• Selectable fail-safe or fail-secure operation.
• Selectable Presence or Pulse operation.
• 4 selectable sensitivity settings and sensitivity boost allow for a wide range of uses.
• Loop monitoring provides a fault display when a loop failure is detected.
• Fault memory gives a unique display when a fault has occurred, but the system is currently functioning properly.
• Flicker display shows occupancy of the detection zone after a pulse output has been generated.

• Loop Inductance: 20 µH to 1500 µH (including lead-in inductance)
• Operating Temperature: -35 to 165°F (-37 to 74°C)
• Operating Voltages: Relay: 10.5 to 35 VDC, 9 to 28 VAC; solid-state: 7.5 to 35 VDC, 6 to 28 VAC
• Operating Current: Relay: 120 mA maximum, 25 mA typical; solid-state: 65 mA maximum, 25 mA typical
• Output Ratings: Relay: 1 A @ 125 V; solid state: 50 mA @ 30 V
• Pulse Output: 150 ms on period followed by a 150 ms off period before the next pulse can begin
• Response Time: 150 ms ±25 ms
• Housing Size: 2.36 in (H) x 1.75 in (W) x 4.09 in (D)

Two-loop directional detection, so the gate or arm responds only to traffic moving one way.

• Entry and exit lane direction sensing
• Wrong-way detection at parking lanes
• Barrier arm lanes
• Commercial gate entrances
• Parking garage ramps
