Diablo DSP-7 10-30 VAC/DC Loop Detector (Fail Safe)
The DSP-7 detector adds yet another new dimension of simplicity to
vehicle detectors. This detector has been specifically designed to handle parking, drive-through and access control applications and operates on any voltage from 10 to 30 Volts AC or DC. Loop Size - Works on any in-ground inductive loop from 20 to 1500 μH. Indicators - Separate Power/Fail and Detect LEDs. Detect Memory - Power interruptions of short duration are ignored. If power fails for approximately 1½ seconds or less the detector “remembers” a vehicle. Sensitivity - Automatic - compensates for large loops and long lead-ins. 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 “Fail Safe” detector should always be used on “safety” loops.Power - 10 to 30 Volts AC or DC, 25 mA max. Outputs - Both N.O. (closes for detect) and N.C. (opens for detect) outputs. (1 amp max.) Size - Height: 1.52" Width: 2.9" Depth: 1.56” Connector – Removable 7 position terminal block. Pin assignments are:1 - Output relay (N.C. - opens for detect)(1 amp max) Presence2 - Output relay common Presence3 - Output relay (N.O. - closes for detect)(1 amp max) Presence4 - Power common5 - Power in (10 to 30 Volts AC or +DC)6 - Loop input7 - Loop input Operating Temperature - -35°F to 165°F (-37°C to 74°C)
