This low powered vehicle detector is perfect for solar powered applications!
Automatically adjusts its sensitivity level when used on different sized loops.
Covered by United States patent number US 7,132,959 “Non-Interfering Vehicle Detection”.
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.
Fail Safe vs Fail Secure Info: 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 flow to continue. A fail secure
detecor will never output “detect” when theloop circuit is failed. This
will keep the gate closed. This is useful in high-secure areas or
installations where containment is needed. The DSP-7 is a fail safe
detecor. 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 1 mA current. The relay contacts are rated at 1
Connector: Removable 7-pin terminal block.
Pin assignments (from left to right) are shown below:
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″
