Diablo DSP-7LP 10-30 VAC/DC Low Power Loop Detector (Fail Safe)
Diablo DSP-7LP 10-30 VAC/DC Low Power Loop Detector (Fail Safe)The DSP-7LP vehicle detector has been specifically designed for solar
powered gate applications specifically for “fail safe” operations, such
as on safety loops. This detector will operate on any voltage from 10 to 30 Volts AC or DC
and draws approximately 1 milliampere while waiting for a car. The
power LED winks continuously once per second to indicate the detector is
operating in the low power mode. The DSP-7LP detector has many of the
same features as our standard DSP-7 but beats all competition for
reliability, simplicity, and "no car" current consumption.Loop Size - Works on any in-ground inductive loop from 20 to 1200 μH.
Indicators - Separate Power and Detect LED’s. The
green Power LED will wink continuously once per second under normal
operation. The red Detect LED will turn on solid for a vehicle.
Sensitivity - Automatic - compensates for large loops and large lead-ins.
Output Ratings - Single output, 1 amp relay at 30 VDC
Resistive - The relay common, NO, and NC contacts are available.
Loop Failure - The green power indicator flashes
twice per second if the loop circuit is open and 10 times per second if
the loop circuit is shorted. This detector operates in the fail safe
mode and will output a “Detect”for either of these loop failure
conditions. This “Failsafe” detector should be used on “safety” loops.
Power - 10 to 30 Volts AC or DC. Approximately 1
mA (no car and all loop sizes) and less than 25 mA with a car on the
loop or while in a “Fail” condition
Size - Height: 1.52" Width: 2.9" Depth: 1.56"
Connector - Removable 7-pin terminal block. Pin assignments are shown below - from left to right: 1 - Relay (NC) (opens for detect) Presence2 - Relay Common Presence3 - Relay (NO) (closes for detect) Presence4 - Power Common5 - Power in (10 to 30 Volts AC or +DC)6 - Loop7 - Loop
