Diablo Controls DSP-7 Micro Loop Detector
DSP-7, Vehicle Detector
This detector operates on any voltage from 10 to 30 volts AC or DC and draws about 35 milliamp of current with no vehicle on the loop.
This micro-sized detector will automatically adjust its sensitivity level when used on different sized loops.
The detector loop inductance should be between 20 and 2000 microhenries.
This series of Diablo Controls detectors are covered by United Stated parent.
Patent number US 7,132,959 "Non-Interfering Vehicle Detection."
Plug ang Play
Designed to be cross talk free between other loops
Automatically compensates for loop and lead-in sizes
Fail Safe Operation
Wide low-voltage operation
- LED Indicators: The green Power LED blinks once per second to indicate the detector is operating and powered.
The red Detect LED will turn on when a vehicle is over the loop detection area.
Loop or Wire Failures: In the case of a loop circuit failure, the green LED flashes slowly (twice per second) for an open loop circuit failure.
The green LED will flash fast (10 times per second) to indicate a shorted loop circuit.
Fail Safe vs Fail Secure: A fail safe detector will output "detect" when the loop circuit is failed. This is always useful on a safety loop.
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 glow 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 DSP-7 is a fail safe detector.
Note: Never use a fail secure detector on a safety loop.
Power: This detector is powered with 10 to 30 volts AC or DC. Approximately 35 mA current.
The relay contacts are rated at 1 amp maximum.
Connector: Removable 7-pin terminal block.
Pin assignments shown below (from left to right).
1: Relay Normally Closed (NC) - contact opens for detect
2: Relay Common
3: Relay Normally Open (NO) - contact closes for detect
4: Power common
5: Power in (10 to 30 Volts AC or +DC)
Size: Height: 1.52" Width: 2.9" Depth: 1.56”
